Photography is not just about pointing and pressing a button; it's a decision-making process. One of the best reasons for working photography into your activities and projects is that it helps people better understand the media images they're bombarded with every day. Photography is also just plain fun, and it's a wonderful foundation for community-based projects. If you introduce photography properly, it helps you look much more carefully at the world around you. When you buy a digital camera, you have to know how to take care of it to keep it in its best condition. In order to have the clearest photos possible, you must make sure to regularly clean your optic lens and keep from leaving fingerprints on it. If this happens, parts of your pictures will be blurry, and dirt can build up over time. Not all cleaning products are suitable for a camera lens, so make sure that you don't use tissue paper, any household cleaning solutions, and definitely not saliva. Instead, you should buy the proper products at a camera store, in order to keep your camera at its best. The autofocus of most cameras has a two-step shutter release. Pressing the button down half-way locks the focus of the picture, and pressing it down all the way takes the picture. Depressing the shutter only half-way allows you to select what part of the picture you would like to be clearly focused; after holding the button halfway down, you can move the picture so that the subject is where you want it to be and yet is still focused. Always press the button gently, not jerkingly, so as not to move the camera too much from the frame and composition. When you look at a picture where there are objects in the foreground and in the background, you may notice that, besides your main subject, some objects in front of your main subject and going all the way back to behind your main subject are also in focus. This "zone of sharpness" is called the depth of field. The depth of field is dependent on the aperture you are using, the focusing distance, and the size of the projected image. The depth of field decreases as you open up the lens, i.e. as you move to a larger aperture. It decreases as you move closer to your subject. And, at a fixed image size, the depth of field is the same irrespective of the focal length used. You would want to use a shallow depth of field to isolate your main subject from its surroundings, as in a portrait. You can accomplish that by moving in close, by zooming in (again, because it makes the background appear larger and more out of focus) and/or by using a large aperture. A great technique that helps photographers create eye-catching pictures is the rule of thirds. This is a composition technique, create a pleasing balance between the different obects in a photograph. In order to use the rule, divide your screen into six different parts: three horizontal sections, and three vertical. The focal points, where the eye is attracted when it first looks at a picture, are where the lines intersect. Placing the subjects of your pictures at or near the focal points can help create a balanced and attractive picture. Landscape photos are very popular and can be very nice-looking. The whole photograph will need to be in focus, unlike some pictures where only a certain part is in focus. In order to have the picture completely focused, you'll need to have a short focal length. This will create a larger depth of field, and everything will be focused. In order to creating a pleasing balance between land and sky, or water and sky, you can use the rule of thirds. Furthermore, if you want a sense of three dimensions, you can have a subject in the foreground. A tripod is a good investment in photography, especially if you want to take panoramic pictures. You'll have to set your tripod in a place where you can swivel the camera smoothly from left to right, and not up and down. You will have to figure out where you want your pictures to overlap, so that you don't have huge gaps in your resulting picture. Once you figure that out, you can swivel your camera in one direction, clockwise or counterclockwise, to take the pictures you want. Once you're done, all you have to do is put them together with a simple graphics program or photo-editing software.
