Finally, all the great photographers, with some technical aspects of photography, has burned rolls of film or memory cards to load your face! Two homes in particular, to address the exposure (in another article) and the depth of field (or DOF), the amateur photographer bitten by newcomer shook his head, wondering what harm they do.
When I started the role of informal education with the photographer at the beginning,E 'was interesting to note that the most common question asked: "How do I make the background blur and sharp on me? And, of course:" What do I do if I want to concentrate? "
E 'inevitable. If you want the photo to a higher level of quality, you have to understand what short and long term causes of manipulating the shadows, and especially the ways to express your vision. Let's get started ...
Firstly - a photo with a briefDepth of field, and what you must, with degrees of freedom of time? It's easy to focus on a photo with the theme, and everything blurred in front and behind him is a photo with a short DOF. A table with everything in the foreground, background, and specific guidance has a long DOF. With this advanced formula, I'm sure you can imagine what an average depth of field!
Why use a shorter DOF? When you reach this level of control exactly what you want in focus (usually calledas selective attention) of your photo will be a dynamic tool designed to create powerful photo! See this widely used in photo-journalism - as the photographer who focuses on a particular person in a crowd. The creative use of this tool certainly gives substance to the notion: A picture is worth a thousand words!
Often you will see the use of short DOF portraits glamor. A classic example is when you use the model to copesharper focus the lens, and another is unclear. He is capable of using any of the more unusual for a photographer to give him or his message.
What about a DOF long? The landscape photography is the best example of the depth of field long in use. Take pictures of landscapes seemingly endless Photography useless if only a small part of the "box" was. Given that virtually everything about you then run by Tack Sharp - arewants to shoot with a long DOF. You can use this with an incredible result in the greatest works of art photographers like Ansel Adams and Edward Weston. But even with pictures of spectacular scenes, there are times when you want creative ideas, priority will be to focus on the spectacular formations, a small delicate flower in nature. The development of these techniques, you are armed with this kind of versatility photography.
So now that you understand what is the depth of field,How do you do this? This is where we start to get a little technical, but it is important to understand. Since DOF varies according to the focal length is that you can use my examples are in connection with the use of a standard lens of 45 millimeters reflex - 70 millimeters range. DOF is necessary to be able to manipulate to set the opening (or openings) on the camera. Almost all SLR cameras that can even remotely do this by moving the modern wayAperture Priority - or AV mode.
Although I do not give a detailed explanation of openness in this article - is the easiest to understand: an F-stop opening and regulation that controls the amount of light is focused through the lens of film or digital sensor. The speed of ' shutter is also this, but for now stay with Aperture. The opening also controls the DOF of an image.
Typically aged SLR camera lenseshave the F-stop numbers on the lens. An old simple goal, the number of openings ring just as we 2,8-5,6 - 8 for the 11-16 May 22. These are the f-stop or aperture settings.
New cameras are electronic and the F-stops are usually at the bottom of the viewfinder to see. F lenses are generally more modern-stop settings are available, for example, 2,8-3,5 - 5,6-6,3 to 7,1-8 - and so on, perhaps all the way up to 32
To selectDOF for one particular shot, you must understand this concept is very simple to use: The low F-stop number - such as 2.8, the shorter the DOF will be. The greater the number of F-stop - 22, plus the depth of field. To further simplify - to take a photo with F22 or higher, while the point of the final image. Filming is set to open at 2.8 means that only what is specifically focused on too strong.
Take a moment torecord, because this concept is the basis nuts and bolts of creating an image of quality and not just taking a picture. The best exercise you can do to practice this technique is the line up to 3 properties - such as apples, for example. Placed on a table 2 'was walking by you in a corner just enough to the first, not lock the other two. Turn your camera over 3 'of the first, and focus on the apple in the middle. Shoot more shots - each inanother F-stop, starting with the least number of short DOF) and transition (to the nearest f-stop after each shot ... to the maximum F-stop.
If the target is an F-stop number, the lowest 2.8, you will see that perhaps the front of the Apple glance - everything from the other more clearly. Every time transformed into a larger number F-stop, you'll see more of center field. Over time we reach the highest F-stop settingvirtually everything that this image will be highly concentrated.
Most SLR cameras have a DOF preview button. If you use it while through the lens of the scene - you'll see what the final image will appear. The only problem is - the higher the number of F-stops, the greater the amount of light is left so that it can be very difficult to see why it's very dark. After practicing these techniques do not bother with the DOF preview button. Know,are reproduced as the image.
This is the secret of the depth of field in the near future, yes, there are particular aspects of DOF - namely the hyper-concentration and understanding of the course you get different results degrees of freedom with a focal length longer and short. But revolutionizing the understanding of these basic concepts DOF your picture and give you a little 'higher quality and photos.
