Digital Slr Cameras Basics
So you just bought a shiny new camera huh SLR? And a lens or two to go with it? That's great. Now all you have to do is learn to use it. I'm assuming here that you bought an SLR camera because you want to do a little more than happy if you hold family events and holidays. So for those photo again as nothing more than that, this article aims to give you a little background on the basics of exposure to help you on your way.
Shutter speed
There are two elements to create an exhibition "correct". These are the opening and shutter speed, we look first. When you press the shutter of your camera to take a picture, opens a set of indicators, such as opening a window. How long it open, depends on how you set the shutter speed. Shutter speeds can range from a fast 1 (ie / 8000 second), that very slow (30 seconds), or even infinity if your camera has a bulb setting. These are extreme shutter speeds and often not used, except by people who shoot fast-moving subjects or in very low light. For most of us tend to be somewhere in the middle. As a general rule, The higher the speed shutter, your picture will be clearer. For most people, all at 1 / 60 second or more is acceptable when a hand holding a camera. Minor if you have a particularly steady hand. If you need shutter speeds slower, you need to use a tripod or rest your camera on a firm surface. These slow speeds can be particularly useful for creating blurred. For example the water that flows into a waterfall.
Aperture
Ever wondered how photographers get their themes that really stand out by blurring the background? The secret (which really is not no secret) is to adjust the opening. The opening changes the depth of field in your photo. Depth of field is how the image is in focus. For example, if you have a depth of field of 4 meters, any something within that distance of the subject you are focusing also be in focus. There is so much variety with this control, it is with the shutter speed. You can choose to set a narrow aperture (depth of field of long-term) when you want the entire picture in focus, for example, a landscape, large scan, or a larger aperture for portraits.
Ok, so you have your shutter speed the discussions of the opening. Now we just have to put them together. Any camera SLR has a built-in light meter. This little gadget measures the amount of light you need to create a correct exposure. It is usually in the form of a small bar with a very high (+) and a very low (-) sign at each end. It is simply a matter of balancing one against the other so that the meter is centered. Since you did that you can press the button! That's all there is to it.
ISO
Another choice that will affect your exposure is ISO you use. With film cameras, this means the film speed you use. If you use a 100 speed film, ISO is 100. Digital cameras also have an ISO speed adjustable. It is only in the form of making a connection instead of loading a different movie. The general rule is to use the lowest ISO you can get away with. High ISO film or digital settings can result in noisy (grainy) photos. They, however, allow you more freedom in their exhibits you can shoot with less light available. Experiment with your particular camera, see what you can get away with. Remember that the quality required to be different for everyone. If you just want to make small prints to put in an album or just store the digital photos on your computer, then you will not the same quality, if you want to make large prints to hang on the wall.
So there is some food for thought for those beginning in photography and trying to do more than just point and shoot. Now it's time to get out there and shoot. Experiment with different settings. Try new things. The technical side Photography you can read anywhere. The first creative, well, that's up to you.
