Playing With Shutter Speed
If you have just got your first Digital SLR camera, you might have realised that there are many settings to chose from. Each is uniquely designed to produce different outcomes and different styles of photo.
If you are looking up special effect photos on your laptop, or you are on a phone network which provides internet services such as O2 or Three, then you may have seen some stunning photos which play around with the shutter speed. These include flowing water which is cleverly made to look smooth across the rocks, or the headlights of a car which seem to have been dragged across the photo. These are easy to achieve, providing you know which settings to use.
Smooth Water Effect – If you want to take a picture which shows smooth and wispy water, then you want to set your camera to shutter speed priority. A short and fast shutter speed does not let much light in, it is primarily used for bright settings or action-shot photos. A slow setting however, absorbs much more light, this is mainly used in darker situations, or for special effects. If it is a bright day and you wish to take a photo of a small river or a waterfall, firstly lower your ISO setting to 100 or as low as it can go. With a tripod, balance your camera in position and select Shutter Priority. Set the speed to minus 2 to begin with – this will hold the lens open for 2 seconds, giving a slight motion effect to the water. On the other hand, for a wispy and silky water effect, lower the speed to approximately minus 10 seconds.
Slow Shutter Night Photos – If you want a photo where the colorful headlights of cars are dragged across the image, then these photos must be done when it is very dark. Find a busy road and perch yourself on a nearby pavement. Fix your camera to the tripod and point your lens at the busiest point in the road. This time, turn up your ISO to about 400-500. To capture a small light-drag, set the shutter speed to minus 2 or 4. However, for a long light beam, set it slightly longer.
How to Shoot Farm Scenes with Modern Digital Camera?
For many of us, travel to a farm can be few and far between. As someone who is very fond of long walks in the English countryside I often find myself coming through farmland that offers a wealth of photographic opportunities. So with a lot of issues to cover, here are some tips on how to maximize your next trip to the farm for farming! Going to the farm to take photos is not necessarily an option for a photographer typical location, but due to the nature of a farm, you may find commitment to a wide variety of photographic subjects – landscapes, animals, architecture, neglect, food , and produce.
No need for special equipment to get great shots, but due to the diversity of matter, rather than the camera has, the easier it will be. You may have more control, and adjusts the settings according to their subject. There are some things you must consider before making your trip to the farm. First, that farm? There may be a local farm on or beside a path that you already know that you may want to visit. This is more or less until the investigation! Whether you’ve been before or not, it is always best to ask farmers for permission beforehand. You want to avoid trespassing and photographs in the lands of another without his consent. Most owners are happy to help, but not just turn up uninvited!
Your best bet is to look online and in local newspapers for school agriculture farm and open, which invites the public to come and see the animals, especially during the lambing season. This can be a hassle-free way to get up close to animals without any restrictions. With this in mind, you also want to consider carefully the time of year you visit. The farm life is almost entirely dictated by the seasons, so that the activity, animals and the issue of exploitation vary greatly from month to month. Think about whether you want to find a newborn animals, such as birth season is early spring, or had imagined taking pictures of the fully developed crop, which will be at its peak in mid-summer. Obviously there are tight deadlines for this activity, but I’m sure the farmer is happy to inform you of what is happening in a specific time of year. With regard to seasons, time course into account, many of the shots outside.
Working with animals is never easy, especially animals that are fully trained. When the farm, be patient – as opposed to a cat or dog, these animals are not likely to take direction from you, so you have to work with them and their movements and reactions. You must get a good angle, and when you have the shot in the viewfinder that will have to take their chance, as before you know it, the animal turned and it’s too late! Consider carefully what you want to focus. If you’re focusing on the animal’s face, which works well to focus on the eye, but when going for a more complete shot, you may want to focus on detailed skin or coat. Finally, remember to keep your distance, not imposed on the area of the animals, the easiest thing to do is keep the right side of the fence and use the zoom!
I recommend going to hand for most of the shots as this will give you much more flexibility when it comes to getting a good angle shot, when animals and people. You may have to go down to the level of the subject, and the hand holding the camera ensures that it remains easily manageable. If you have more of a documentary photographer, who also worth asking the farmer or farm workers if they can shoot in a work environment in a journalistic context. As with any taking pictures of landscapes, a number of guidelines to help give your shot more impact. Try to find a point of view carefully, and use the rule of thirds to distinguish which is the focal point of that shot. It could, for example, a building, tree or a river. Make sure you have a subject in the foreground, even if it’s just a rock, as this adds a sense of depth. Think of the lines within the shot, whether horizontal or vertical, and the observation that the lines meet and cross. It is also important to think about light and see if this element is likely to change to improve or worsen your shot.
Be patient, especially if you are in the direction of the afternoon when the low light of the sun can really bring to life a shot. Try to have a great depth of field, something like f16 would be ideal, so the whole shot is in focus. If you can, take a tripod and shutter release with you to stabilize the camera.
If you are looking to take pictures of landscapes, it is well worth considering what will be growing crops at certain times of year and if you want to incorporate into your photography. You can work with pretty standard field crops such as wheat and barley, but remember that depending on where you are in the world, there are a lot of fruits, vegetables and flowers, even breeding can make a big issue .
When working with crops, be careful when you walk and drive in order not to disturb any plants, but try it up close for detailed shots and shots capture a larger scale.
It is also worth asking if the farmer has some freshly harvested produce, or go to a local farmers market to get some pictures of fruits and vegetables on the screen. Architecture on a farm can vary decomposition abandoned huts, cute creepers covered rural farming, barns to industrial production line. You never know what you are getting, so be prepared.
Older buildings tend to have more character and features to work with and it’s great to try to highlight those to show the age of the buildings. With the new industrial structures like, may be worth trying to grasp an idea with strong clinical bolder strokes of composition, especially if there is really any features to work. In my years of looking around the farms, never cease to be amazed by the variety of things that are to photography, so make sure you have some time to explore in case there is something of interest waiting around the back an old barn. Items such as old machinery, animal housing, stocks of lumber, tools and securities we can all make for interesting shots. Be careful if you are in old buildings as a digging machine age tends to be very dangerous and we do not want to lose a finger!
Not only will come up with some big shots, who can have a greater appreciation of life on the farm and all the hard work that is dedicated to creating products that find their way into the dish of the day!
How to Photograph Flowing Waters?
First, have a think about the context in which you want to photograph moving water. There are a variety of options to choose from and you can download what is most convenient geographically. If you want something dramatic and full of energy, then go to a waterfall, if you want something predictable and easy to work, try a video. If you want something large scale, high head to the coast, and if you want something interesting and creative, and finds a river. Each has its own challenges, but many of the basics are the same, which will come later.
picture of water movement
Before you start going into all the technical details, it is important to remember the foundation of any landscape style shooting. Your photos will look stunning water only by water – you need to ensure that all elements of injection, such as the composition have thought so. This is a good place, considering how the water is moving and if you want to be in front of him or at an angle. Remember the rule of thirds, take into account the lines into the outlet, where the eye was in the box and think if you have a reference point and a point of interest in the foreground to add depth.
Now it’s time to think about the trick, the adjustment of digital camera settings so you can capture the movement. For starters, make sure you have a fixed camera, it would be very difficult to try to capture motion blur with a handheld digital camera, so grab the tripod and ideally use a timer or timer to avoid camera movement. In the camera, select priority to shutter speed. It is not known how long the exposure needs to be, depends on the speed of water and light available, so you’ll have to experiment a little. To compensate for the amount of light entering through the long shutter speed, it is best to select a low opening, something around f16 or more, you can also reduce the ISO.
It may also be useful to use a neutral density filter, which restrict the amount of light entering the lens and allow longer shutter speed.
picture of water movement
It is important to remember that water is not only found in large scale, there is a huge amount captured on a smaller scale, like drops, drips and splashes. You can read all about the making of the perfect drop of water here.
While in larger scale situations, motion capture is opening up the shutter speed to blur motion, when shooting small-scale movement of water is all frozen on the action, so you’ll have a very short shutter speed and probably a good idea to use the burst mode of the camera to capture the action. Try to observe how water reacts with the particular physical movement, this will help you appreciate how photographs.
picture of water movement. So I hope those were some tips on capturing water in motion and you’re ready to go do it. When large-scale natural environments, give yourself plenty of time. You probably will not get it right the first time, but experiment with the settings and be rewarded greatly. Remember that water is everywhere – not necessarily have to make a special trip to look, there are great shots to take the splashing from puddles and raindrops.
How to Use Focal Points in Digital Photography
The next time you take your digital camera out and line up shot of a pause before pressing the shutter button and ask yourself:
“What is the focal point in this picture?”
Some other ways to ask the same question might include – What is the central point of interest? What will draw the attention of viewers in this picture? What makes this image stand out from others? What is my topic? The reason for a focal point that is important is that when we look at an image of the eye usually needs a “resting place” or something of interest to really hold. Without it, you’ll find people just look at their photos and then move to the next.
Once you have identified a point of interest or focal point, then you must ask how we can improve.
6 Techniques for improving the Focal Point in a picture
A focal point can be almost anything, from a person, a building, a mountain, a flower, etc. Obviamente, the most interesting focal point for the better – but there are other things you can do to improve your power, including:
- * Position – Place it in a prominent position – you may want to start with the rule of thirds for some ideas.
- * Focus – Learn how to use depth of field to blur other issues in front of or behind its focal point.
- * Blur – If you really want to get complicated you might want to play with shutter speeds slower if the focus is and things move around.
- * Size – what the focal point of great size is not the only way to be important – but it can certainly help.
- * Color – use of contrasting colors can also be a way to establish the point of interest in addition to its surroundings.
- * Shape – similar shapes and contrasting textures can make a subject stand out – especially the recurring patterns around a theme.
Note that a combination of above items can work well together. Finally – do not confuse the viewer with too many competing focal points that can overwhelm the main focal point. Secondary variables of interest may be useful to guide the eye, but just too strong disorder and confusion.
Digital Camera: Nikon’s Digital SLRs
Nikon is a camera brand, most choice definite for producing SLR camera. As with
the blare of digital cameras all afresh the world, Nikon allied the
bandwagon by producing As they brand best, accordingly the new era of the
Nikon digital camera was natural – digital SLR.
One of the most choice in DSLR, the Nikon digital camera called Nikon D70 is 6-mega pixel Nikon digital camera. Coated after polycarbonate afresh its stainless steel chassis, this Nikon digital camera is furnished after a 50mm AF Nikkor lens that can add after an 18-70mm kit lens and constant be portable sufficient to be approved around. It has a 200-1600 ISO active alacrity range, Almighty for taking film together in the blush and anesthetized the sun. and why won’t it be?! With its three frames per extra constant assassination charge and its 1/8000 extra shutter speed, taking film is as cushy as clicking aside and having fun. this Nikon digital camera is supported after a Flash card.Another SLR as of Nikon is the Nikon Coolpix 8800. An 8-mega pixel Nikon digital camera, the Coolpix 8800 has a centralize body. Furnished after a 1.8 inch flip-out and swivel LCD, this babe is assuredly earliest charge SLR. This Nikon digital camera complexion an canvas stabilizer ecosystem to abridge camera shakes distinctively on long shots as this device can dart up to 10x (optical zoom) and can attend to up to 3cm in macro average after its 35-350mm lens. Key wheel are absolutely user-friendly, after modes such as sensitivity, canvas size/quality and white account – create baldly after the average dial. The canvas output aspect is the center announce of this Nikon digital camera, after Almighty delegate rendition, blush constancy and saturation. a comparatively bravura aspect of the 8800 is the constant assassination modes, anywhere users can prefer 1.2 or 2.3 frames per second. A bit big to bear around, the 8800 is accurate for assassination act and sports shots. The 8800 cogs after a Compact Flash certificate for storing up your images. Another digital SLR as of Nikon is the Nikon D50. A 6.1 bumper pixel Nikon digital camera, this device has 7 Catholic modes to assassinate as of using its AF-S DX Zoom Nikkor 18-55mm lens. These modes are Auto, Portrait, Landscape, Close Up, Sports, Night Portrait and Child. To see the images that you took, this Nikon digital camera is furnished after a 2.0 inch LCD screen. How breakneck can this camera shoot? It has 2.5 frames per extra and after continuous assassination of up to 137 frames per second. This Nikon digital camera is not too bad, doubly for apprentice photographers. This package too includes a software for affecting up, suppression and apportionment your pictures. The software constant enables you to blaze your images to VCD or DVD format. One of the earliest aim and assassinate Nikon digital cameras is the Nikon Coolpix 4800. A four bumper pixel Nikon digital camera, the old academy aimed 4800 is fortified after a 1.8 inch LCD cloak for viewing your pictures. The 4800 is an 8.3x dart Nikon digital camera after 6-50mm Nikkor Ed lens that zooms agilely and has constant car focusing (a aspect anywhere your lens is forever difficult to carry your film sharp). It too allows users to shoot, album and playback abrupt movie clips after its aid and choice scene modes – definition that includes delivery outlines for portraits (for tweaking purposes), airing and allergy settings. These complexion are absolutely accommodating doubly for apprentice photographers that absence to try their hands at photography. Along after that, it comes after a 13.5MB SD certificate and the Li-on arsenal pack. ??? Remember to audit out Nikon’s website at nikon to see the latest Nikon digital cameras.
Get Rid Of Old Film Printing Habits
Digital photography is very different than old analog film photography. One big difference is the ability to view the photos in many new ways in addition to using photo prints.
More than a few photographers and amateur consumers are so used to printing film photos and watching photos printed on photo paper that they take their old habits and apply them to the digital photography era. With digital photos, however, there is no reason to always print your digital photos. Digital photography allows many other usages rather than just prints.
Digital photo printing output is very similar to the old film development process. The output of printing analog film photos or digital photos is the same – a piece of special paper with the photo printed on it. The usage of the printed photos is also the same. They can, for example, be put in a photo album or hung on a wall. Although sometimes printing digital photos is a good and useful thing to do, many times it is just a result of old habits, and by doing so users miss a great opportunity to explore photography in new ways.
For example, photo sharing is much easier and faster using new electronic tools rather than old photo prints. Even today you can find users that share photos with family by printing them in the local photo printing shop and then mailing them using regular mail service to their relatives. This process is slow, expensive, and wasteful in material. With digital photos there is a much more convenient way to share photos with family and friends. As opposed to mailing photo prints in the mail, this method is totally free, is instantaneous, and does not waste any real tangible materials.
The method is simple. Upload the photos you would like to share from your digital camera to your personal computer. After doing that, simply email the photos to your friends and family. Sometimes the number of photos is too large and the total size of the files to email is too large for most email services to send. If this is the case, you can use one of many free online services that allow you to create private photo albums and share them with your friends and family. Simply create an account with one of those services and upload your photos. You can also enjoy other feature they provide like automatic red eye reduction photo rotation and other effects.
But the magic of sharing photos does not stop here. With digital photos and the Internet you can also share digital photos with the general public. Using one of the many sharing photo services you can create public accessible albums. You can even create your own photo blog. For each photo you upload you can write a few words explaining the photo and have viewers that want to write some comments and thoughts about the photo.
So next time you are printing digital photos, think twice about why are you doing it. If you are aware of your other digital options and in real need for photo prints then go ahead and print. Make sure that you are not printing digital photos out of habit and not out of real need.

Who Can Sell Photos Online
Now this is an interesting question I get from photographers who believe that this online digital photography business is only valid for US citizens.
First and foremost I want to say that this is not true; however, I need to add that the typical consumers of stock photography are from the US due to the large amount of Internet users as well as the high demand from advertisers and marketers for images of objects, animals, scenes and a variety of other items that are not found inside the USA.
Google Images is a perfect place to view the variety of subjects that are being photographed and sold via the Internet. However, while you may be seeing the variety, you certainly need to pay attention to the quality as most of the photos found here would not typically be accepted by a Stock Photography site simply because the quality is unacceptable. By visiting stock photography sites and comparing you will see what I mean by quality, also pay particular attention to which sizes are available to upload, this is important to know prior to submitting your image as you will want to make sure you have proper sizes. An important thing to note, try to not resize images as you will be losing quality each time you do.
While looking at the differences between Google Images versus stock photography sites you may notice the distinction between poor quality versus high quality is not that large of a leap yet you want to correct any mistake prior to submitting your image for sale so you don’t risk rejection right off the bat.
You ideally want to submit photos that have not been edited with photo editing programs such as Photoshop. While these programs are great for resizing and cropping you will lose quality each time you open and work with the photo. The goal, therefore, is to take the perfect photo without the need for any editing.
The best thing about this opportunity is that it can be done by anyone, anywhere. All that is required is an Internet connection, a digital camera, a computer and an Internet connection. Combine quality with an interesting subject matter and soon you will be able to sit back and watch your bank account increase.

A Basic Intro To Macro Digital Photography
We constantly discover that seeing things from a fresh perspective is intriguing. When looking at different angles and a different focus, you can often see new things, even when looking at objects that are familiar to you. This may be why people are so drawn to digital macro photography. Beyond functionality, digital macro photography is cherished as an art. This is indisputable. Not everyone can take an ordinary object and turn it into a symbol of life itself. Art is, after all, about capturing the aspects of the world. Art is a representation of the artist’s vision and perspective of the world.
We can all share our view of the world through looking at art, such as digital macro photography. It is important for you to realize that digital macro photography can be quite complicated. A lot of factors should be considered in order to produce great photographs.
Some of the general factors that you should consider are:
1) Skills – you need to determine if you in fact have the talents necessary for digital macro photography. Will people who look at your photographs notice and appreciate the eye for beauty you have? That is not the only thing that you need to be a photographer.
If you are going to handhold the camera, you should remain as motionless as possible. When you take digital macro photographs, even if you move your hand slightly this can mess up your photo. Steady hands are a must.
In order to use a camera properly, you need to learn the skills necessary for taking quality photos. Learning to adjust the camera will allow you to take the picture exactly how you want them. Using the computer to edit a macro paragraph is more work than necessary. Some have a natural ability in this area. However, education is important to keep your skills current. Keep in mind that digital macro photography is essentially about viewing and demonstrating things from a different perspective. Because of this, you must live with the fact that other people may view your work with a different eye than you. Being able to accept criticism is a good trait to have if you are creating artistic works of macro photography.
2) You also need the proper equipment in order to express your talent. When you are looking to achieve that special macro effect, using the right lenses and filters will make things much easier for you. This article will not broach the subject of lens and filter selection, but ideally you should search for tools created specifically for digital macro photography. The reason is that this kind of equipment helps to elicit your ideal abilities. It is necessary to have the appropriate equipment, since digital macro photography requires a lot of effort to be perfect. You can make the pictures the way you want them if you have the right digital macro photography tools and software.
3) Subject–depending on how you look at it, anything can be interesting. Keep in mind that some subjects will hold your interest more than others. When you choose some objects as subjects of digital macro photography, you will be amazed at the amount of knowledge that you can acquire. Excellent topics of digital macro photography show a whole lot more than what you see with your natural eye. For that reason, it is necessary to select your subjects carefully.
Understanding Photography – How Digital Camera Works
In this tutorial, you will begin to learn the basics of digital photography – the criteria by which you can begin reading and using more advanced exercises, and manipulating the camera’s manual settings. Here, exposure as to cover the camera works, shutter, focus, exposure, depth of field, and ISO.
Like all specialized field, photography is a lot of jargon. This tutorial introduces terminology of the camera, if necessary, but I consciously avoid most of the tutorial easier if the word should convey the same meaning. We want to learn here are the concepts of photography and words play a newly introduced, which are not yet aware of gets in the way of it.
Finally, these concepts apply to photography in the broadest sense. Whatever type of device used, the most basic principles of photography apply.
1. Making the exposure
What is the “exposure”? This word can be one of the more confused you will encounter. It is used in many different contexts and has a slightly different meaning in each. Comply with this wider sense, exposure, in a word, the image taking (or whatever you have taken.)
When you press the camera button, which is literally “expose” the light. All images are captured light. No light, no picture. Again, is reduced to its most basic level, we see the things we see reflected light on things.
rock
The light reflected in her eyes is the way you look – and how the camera sees.
Think for a moment. Take something simple like a stone. If you hold in your hand, go outside and watch in broad daylight and you see a cliff. Take it indoors under artificial light and you will always see a cliff. Take in a darkened room where there is no light at all. You can feel the rock, you know, it’s still there, but you can not see because there is no light. Throughout what you were looking for were not even rock, but the light reflected from the rock.
When we take a photo, we’re really doing is to record the light reflected in all this camera is pointed at. That exposure.
2. Recording what the camera sees
The next step in our journey to understanding how cameras work to learn, to be precise, the camera records what is exposed. Most popular today are digital cameras. These are highly specialized chip inside them which is extremely sensitive to light. Interest to keep this tutorial easy to follow, I’m going to call it a “film”.
The chip is the “film” of digital camera used to take pictures. The film is familiar to most people because, before the digital cinema is what you use to record our programs. In this case, the film was, literally, a thin plastic film that are coated in chemicals sensitive to light. Before the film, photographers used glass plates that had often to meet with the chemicals themselves. Kodak, Fuji and Agfa were not in the business yet!
Chamber, its most basic, is simply a box light resistant. It is an opening that is covered with a dark curtain is called the trigger. Directly in front of the gate, if you put the lens. We say both the shutter and the lens even more.
When you press the button on your camera to take a picture of what happens is that the shutter opens and exposes “film” to light. Just a very short time. Less than a fraction of a second. The film is so sensitive to light than the very short exposure is all it takes to see and record what was in front of the camera when the shutter is open.
Back to the good old days of movies, then you need to promote the film. This was usually done either by a lever on the camera, a rear wheel or a motor-drive mechanism built into the camera. He was shooting the film on a track to reveal a new game.
If you never have shot all the films of a film box, just know that is about 1 / 2 “(24 cm) high by about 3 feet (1 meter) long. Each time you press the button and open the door, only a very small segment of the film (about 3 / 4 “or 36cm) is exposed to light. The rest have been carefully protected. In the days of very old glass plates, the photographer had to actually remove plaque from the unit and store in an airtight container to the birth until he or she could develop. If you want another image, had to insert a new glass plate.
In the digital age, saving the chip inside your camera image is recorded on the camera’s buffer in memory. After the chip stores its information to the buffer memory device, it emerges and is ready to take another photo. buffer of the device’s internal memory can usually keep all the image information 09:55. Meanwhile, another process still takes all the information in the buffer of the device internal memory and writes on the card. (Most digital cameras use some type of removable memory cards. CF and SD cards are more popular today, but there were about a dozen different types over the years.)
This writing of the paper is a relatively slow process. Therefore, the camera uses internal memory buffer, so that it can be ready for the next shot more quickly than expected to write everything off the card.
3. How does the trigger
Understand exactly how the components is not necessary to take good photographs, a discussion that follows, because it can help others understand the basics of photography.
shutter
Shutter.
First, let us define some concepts.
Setting: This is another word that has a couple of different meanings. For example, an exhibition (an image) can also be called a frame.
For purposes of our discussion on how the blinds work, opening the frame in the camera body, the closure lid. When the shutter is open, the light passes through the frame display image.
Curtain: What often generically called “Shutter” is actually a collection of parts. More importantly, there are actually two different shades that make the whole shutter assembly. For our purposes, we should be able to refer to each of the shutter curtains individually.
The first (“A curtain”) is attached to the top of the frame. It extends to cover the structure and contracts up to expose. The second (“B curtain”) is set at the bottom of the frame. It extends upward to cover the structure and contracts downward to expose.
Suppose A is now extended scenes, covering the structure. Cortina B is under contract, leaving the curtain to do the job of blocking the passageway.
When you press the button the camera takes the picture, the following sequence of events occurs:
* A curtain of contracts on the rise, exposing the frame.
* Curtain B expands upwards, culminating with an exhibition frame.
Intermediate to these two events is the shutter speed. The next time you press the shutter button, the curtain of agreements downward B after the curtain extends downward. Continue alternating in this way of life of the camera. There is an old film cameras with no engine to drive the curtains are not a substitute. Rather, the “tune” the shutter winder, your return after exposure, but all the other principles described here are still valid.
A slow shutter speed (ie, 1/15th second), the movements of the two curtains can be separate events. For almost the entire duration of the exhibition, the story is left completely free. A fast shutter speeds (half is 000 seconds), two curtains can be moved at the same time with only a slit between moving up (or down) through the frame.
Assuming that there was only one curtain. (Take A. curtain) curtain will fall up to after the time set by the shutter speed, extends down to end the show.
The top would be the last light exposure and the first tank. For a relatively long (c.-à-1/4ème second), the difference in exposure time between the top and bottom of the frame as a percentage of total exposure time would be negligible and will hardly notice a difference. A shutter speeds (ie 1.1 seconds 000th), the difference in the percentage of the total exposure time is much larger. It ends with an image that gradually darker from bottom to top.
Having two shades also accelerates much faster shutter speeds. Think about the mechanisms involved in an object moving very fast in one direction, stop, then turn around and move very quickly in the opposite direction, while allowing you to maintain precise control over speed. Even if this could be done, the mechanical stress would lead to faster wear and tear more.
4. Bring to Focus
In its most basic form of all, we’ve covered all what is technically necessary for the photo: a light sensitive medium (film or digital camera chip), a light-tight box (the camera body ), an opening to allow light to reach the film (in part) and a means to control the light entering the film (the shutter). If you were to make a pinhole camera, these are all the parts you need. Everything else is just a photograph “best” faster, more convenient and flexible.
The next part we will add to this basic configuration is the goal. The camera lens can be permanently fixed or be allowed to change lenses.
What purpose do is take all the light in front of the camera and focus.
Projector
A projector has a fixed point of focus.
Think of a slide projector to the former or old film projector. If you take a strip or a portion of the film strip and took his place between light lamp and wall lamp would not project any kind of meaningful picture on the wall. At best, you will see patches of colored light wave. With the projector, using a lens to focus and concentrate the light over a smaller area instead of letting spread in all directions.
The lens in the front of the camera is exactly the same, but in the opposite direction. Instead of focusing the light that would otherwise randomly distributed on the outside, it takes the light which has already spread randomly around and focuses on “movies.” (Incidentally, the eye is a target too. Has exactly the same type of structure and the same basic features that any camera lens.)
Watch how to make a lens and then discuss the mechanics of development. (Let’s skip the opening for the present and speak in their own section.)
spec
Lenses focus light onto the film.
Although the goal is very simple consisting of at least two “elements.” An element is a piece of glass. (I say glass, but could be plastic or other exotic materials.) Each element has at least one curved surface. Look closely at a pair of glasses. You will notice that not only flat plate glass window. Usually, the front of each lens is curved outward, away from the user and is curved back toward the center of the lens and the extent of the company.
In a camera lens, the elements can have a flat surface and a curved surface, which may have two curved surfaces in the same direction (like glasses), or may have two curved surfaces in opposite directions, either both the exterior interior, or both.
If there is only a piece of glass, the light would change, but there is no way to concentrate. Returning to our example of holding a slide or a section of the film strip between a lamp and the wall, if you insert a lens or eyepiece in the equation, you will notice a change in reflected light the wall, but still do not reflect a clear image.
Adding another piece of glass, also at least one curved surface that allows you to focus. Focusing is achieved by moving
the two pieces of glass closer or farther away. (You can also move as a whole, closer or farther from the film.)
When light passes through each glass element, a curved surface (s) “complicated” the beams of light. Most lenses have more glass elements and two together you can bend the light many times more complicated. Sometimes two or more items can be bonded. These groups are called. (Just to keep things confusing, the only element all by itself is also called a group.) So, if you look at the specifications of the lenses, you can see something like “13 elements in 7 groups.” Now you have no idea what that means.
The ultimate goal of all this bending and focusing light rays to form a crisp, clear picture on the film.

5. Fine-tuning Light
With a goal in front of the camera, you can choose between having a sharp image, or one that is fuzzy, but there is really no in between. To modify the effects you can get and expand your creative possibilities, we need to add more.
opening
Aperture.
The opening is a blade assembly opaque to light in a circle inside the lens. The circle is a bit like opening a hole in the center of a donut. (As usual, the word “open” refers to two different things. The same set is called open, or sometimes the diaphragm, but the hole is also called the aperture. When people say concern in opening the hole and not all the parts that make up the hole.) The size of the aperture opening can be adjusted in precise steps to control how much light is allowed to pass through the target and a movie.
While the cameras are not a way to control directly, with all but the simplest cameras employ openings.
The aperture size is not directly measured in units. For example, you’ve never heard someone say “My opening is 10 mm. Instead, they expressed relative to the focal length or zoom lens. It also follows a logarithmic scale, which makes the concept even more difficult for non-rocket scientists to follow. For example, if the opening is 10 mm in diameter and when using a 100 mm lens, which means that its opening was f10. This means that the diameter of the opening is 1/10th of your lens. The same 10 mm aperture in a lens of 50 mm f5 because the diameter is only 1/5th the focal length. (The “f” in this sentence is short for “coordination.” ) Confusing? Sure. But there is a reason. We’re there!
The typical configuration of opening: f1.4, f2, f2.8, f4, f5.6, f8, f11, f16, f22. Each stop is an all – in increments of photography exhibition called “stops” – and each represents half of light passing through the lens of the stop before and after stopping twice. Some objectives can be opened wider than f1.4 or close smaller than f22, but are not common.
Moreover, its objective can not even complete range above. In front of the lens, you should find a mark as “17mm f5.6″ or possibly “17 mm 1:5,6. The f5.6 in our example represents the largest opening available at this goal. So in this example, you can use one of the parameters of f5.6 to f22. The actual numbers of their target and can vary if you use a zoom, has two sets of numbers. The first relates to the shorter focal range zoom and the second relates to the longer range.
So why the gaps are measured, as they are? Understand that you need to know what the gap is actually doing.
* The primary function is to regulate the gap in the amount of light can pass through the lens and get the movie. Since the blades forming the orifice is in the dark, the light passes through the lens of their own through the hole created by the mechanism. One of the things that all the bending of light rays of light is not necessary to go through the hole. In this way, when you close the hole, you do not see a bright center and darker edge.
* A side effect, and most importantly as far as photographers are concerned, is that changing the aperture size changes the way the scene is in focus.
It will take some explanation, so let’s give it its own section.
6. Depth of Field
For example, go back to film or slide projector, a slide (or film) and a flat screen on which images are currently designed to be flat. the lenses are no openings because of the amount of light they put out is a constant and known quantity, and two flat surfaces to enable customers to focus on one point (slide / film surface) to point B (figure).
Depth of field
Depth of field.
The real world is three dimensional. The lens can focus all the light, he looks on a flat surface, but the light is coming from all non-planar surfaces. Technically, a goal can achieve perfect focus on a single plane at a time. As things get away from this plan, either closer or farther from the camera, they released more and more interest. To some extent, because the degree of being out of focus blur is so small that it can not even be detected with the naked eye. What you end up with a series where everything seems to be developed, although technically speaking, a point is currently in perfect focus. This series is known as “depth of field.”
Interest to try to cover all the jargon is likely to come across your photo studios, is another term for the districts of confusion. “Think of a pencil tip. When the pen is sharp is just a very fine point. Suppose that at some point, an important mid-level should be the full sharpness of this pen section. When you use the stylus, it is very tick slowly. line in a multi-rounder, bigger and bigger. The change is not sudden, so many of these intermediate stages of the field could look quite as sharp as when the pen point was perfect. We want to say that they belong to a depth of field. At some point pen tip should be larger and more boring. You can clearly see that it is not as sharp as when the score was perfect. At that time, the circle of confusion is broken, and the brain no longer be confused with the pencil tip ever so slightly sharp a completely opaque.
You know that the pencil is boring, or in this metaphor, you acknowledge that parts of your image is not developed.
How it all belongs to the opening is that when you close the opening of even smaller apertures, depth of field increases. It is of much greater significance in the scene seems to be developed. This can be useful, for example, if you try to photograph a large field of flowers, ranging from a few arm lengths within walking distance of the horizon and you want everything to be developed.

This image of portrait type to leave the background out of focus.
Understanding this phenomenon will help you know that the opposite must be true that you open your open to proposals for more and larger depth of field becomes smaller. This is often used in portraiture, where photographers often as the person you are photographing in focus but the background very blurred and out of focus.
I promised because the values of the gap are hard to understand, to observe that a logarithmic scale, rather than allowing the direct measurement of openness. Now we have moved a bit ‘over the hole and how it works, and covers a few things and focusing lenses, we briefly put together. The reason is that the same diameter of your images will look different when using lenses of different lengths. 10 mm membrane is a very wide 12mm lens, only a modest 80mm and 300mm lens is small. Effect, both in terms of how much light could get through, and the depth of field, it would not be the same from one objective to another.
It would be like saying that a meter, a unit of Singapore, a unit totally different in Norway and a second unit is still in Australia. Without normalization, from a unit to become useless. So instead, the measure is expressed as a percentage of the focal length of the lens. This provides the necessary amount of standardization so that the effect on your photos (at least with regard to openness is concerned) is the same regardless of your lens.
degrees of the scale may seem a bit ‘random, but they are calculated in accordance with the halving and doubling is common to any other action photography. In this case, halve or double its opening, and thus the amount of light allowed to pass.
7. Brightness control over the exposure time
Photographers can be so caught up in the side effect of opening – the depth of field – they forget the primary purpose is to serve to regulate the amount of light can pass through the lens.
We have already discussed that all photography is to collect and store the light. Incidentally, the camera captures all the light is cumulative. Mostly photographic film or digital sensor needs to be exposed to light only a small fraction of a second to capture and store image. When the light is low, you may need to leave the shutter open longer to let more light in
Ferris Wheel
Playing with exposure during the night.
As long as the shutter is opened, your camera collect light. If it happens that your image contains a moving subject and object speed of movement is faster than the shutter speed you use, it will be recorded as a blur in the image. With this knowledge can be very useful.
Sometimes you want your object deliberately blurred or completely frozen. Knowledge about the relationship between shutter speed and the speed of subject movement will help you choose the best solutions. You have no quarter, 000 of a second of freeze all mobiles at a walking pace of 1/125th of a second can do the job.
The conventional wisdom is that fast-moving subjects demand still faster shutter speeds. It may be useful to study the effect of different
taking a picture. Want to stop the action? To transmit a bit of action? Or let the business produces an effect?
Control the shutter speed can be useful or necessary to freeze (or deliberately vague) a moving object. For example, in moving water, a fast shutter speed freezes individual droplets. A very long (slow) shutter speed will produce an exuberant, the effect of cotton candy. There are a wide range of speeds between these two extremes.
8. Photosensitivity
So far we have talked about two ways in which to handle light cameras used for an exhibition: the opening and shutter speed. There are two ways in which the light control cameras. One of the two ways is to add more light. This is usually done using the flash. Flash is a broad topic, which is reserved for its own tutorial. For now, just know that this is one of the tools at their disposal.
The other method is commonly known as ISO. ISO is actually an acronym for the International Organization for Standardization. This is the group that helps set standards for everything from electrical output formats and tires steel hardness and softness of cotton. They also set standards for sensitivity to light.
From a photographic point of view, the ISO is actually a reference to the “sensitivity of the film.” Let’s step back and think of a movie a while. You can walk into any store that still sells the movie and you will find a number of different varieties. You can see the “speed 100″ film, 200 speed, “the movie,” 400 speed “of the film and so on. Alternatively, they can be marketed as ISO100, ISO200, ISO400 and so on. (Note that we’re back in the halving and doubling of values that is the norm in all photographic measurements.)
on cinema in general ranges from ISO 50, ISO 800. Digital cameras typically range between 100 ISO-ISO 400, although some may go as low as ISO50 and is becoming more common to go as high as 6400. In extreme cases, special films can vary from simple ISO number the number of taper ISO 30, 000 +.
The scale is the same for both film and digital. Here’s a quick summary of some large value can be seen:
* ISO 25 is very insensitive, requiring a very bright light.
ISO50 * is twice as sensitive, but still requires a very bright light.
* ISO100 is standard for consumer film and digital photographs. It is mainly used in direct sunlight or the same brightness level.
* ISO200 is the next major increase in size. E ‘announced as “an all-around” cinema. Outdoors, it can be used around dusk and dawn.
* ISO400 is the next full stop. It can take pictures in relatively low light, especially indoors or in twilight hours.
* ISO 800 is for night shots with limited light.
* ISO1600 is for use in dark environments.
* ISO3200 and subsequently for use in very dark environments.
As a general rule, more sensitive to the media (to a higher ISO) images to produce more grain. In some cases the grain can become extreme, also affect image quality. Although often not necessary, it is sometimes used to improve certain “feel”.
There is also an inverse relationship between saturation and ISO sensitivity. ISO100 has little or no grain will be very bright, vivid colors. ISO400 will generally have a moderate grain, but may be sensitive and neutral colors. ISO1600 will often be “extreme” amounts of grain and very mild – almost monochrome – color.
9. Wrapping it all up
Here, we’ve covered the basics of a camera and how the cameras can exert great control of light that makes your pictures. Together, these methods can be used in endless combination to achieve almost any effect you can think of. Each of these side effects that may or may not be desirable for the photo you want to take. Controlling the amount of light arrives, changing the aperture will increase or decrease depth of field. Control how light is the time allowed by adjusting the shutter speed will increase or decrease the motion blur. Controlling the amount of light needed by the evolution of the ISO can affect granulation and color saturation.
No one expects that a mere reading of this article at a time so all of a sudden is an expert on this stuff. You may have read on a couple of times. We recommend that you return periodically to update the concept of memory. The aim is here to help you build a base that allows us to study in other guides, and can be followed, when some of these unfamiliar concepts to come up with.
Good luck and good pictures!
Making Photos on the Beach for the first time
Even if you are not lucky enough to spend a couple of days on the beach during summer vacation, you’ll want to soak up the sunshine at least on a lake or river.
It has long trek to the beach seems somehow incomplete without a camera. Nowadays, this device is just as necessary as sunglasses or a swimsuit. And all because a bright sunny day, constantly folded interesting moments to be captured. And the picture quality is high. This is explained by the fact that the matrix of the camera gets enough light. Bright sunlight reflected from sand, water, evenly distributed across the frame. Therefore, you have the opportunity to take pictures from different angles. Here, you will not have to squint at the blinding light of the sun, because if necessary you can simply change the direction of shooting. Try not to focus all our attention only on friends and nature. Look, for example, what makes your dog. I am confident that these frames you do not do at home.
Do not forget to grab a frame gorgeous fluffy clouds. When shooting against a bright blue sky, you will at least guarantee an excellent background. Half the battle is done! Successfully pick up the subject, and enjoy the beautiful photographs.
