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.

It is quite easy to touch the optics of a camera and leave fingerprints. The result is that your pictures do not turn out clear in certain areas. Or, the autofocus sensors (if your camera has them) can be fooled by the smudge you leave on them, and deliver blurred pictures. Regularly clean your optics with an appropriate cloth and solution (both obtained at any respectable camera store). Do not use tissue paper, your finger, spit or household cleaning solutions.

Most cameras with autofocus provide a two-step shutter release. Depressing the shutter lightly half-way locks the focus; depressing it fully takes the picture. This two-step shutter release allows you to select the part of the picture you want to be in focus (especially if it is not in the middle — usually the focus zone — of the screen), depress the shutter release half-way to lock the focus, and then reframe the picture. Your main subject, even if it is not now in the camera’s focus zone, will still come out in focus in the final picture. When depressing the shutter, do it gently, not with a jerk. Do not hammer it down with your index finger. Place your index finger on the shutter, and let it rest gently there until you are ready to take the picture. Then depress it gently half-way to lock the focus. Reframe, hold your breath, and then depress it fully, but still gently, to take the picture. This helps you maintain your composition and keep your horizon level.

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.

In order to take a panoramic picture, you must have a tripod. Set your camera on the tripod and make sure that it can swivel smoothly only left and right; you don’t want it to go tilt up and down. If this happens, your resulting picture will not look right. You’ll have to mentally note where the edges of your picture are, so that you can know where to overlap the next ones. Keeping the tripod planted in the same place, swivel the camera to one side, left or right, and take a second picture overlapping part of your first shot. Continue to do this until you have all the pictures you want. To put them all together, all you have to do is use a basic graphics or picture editing program to put them all in the right order, and you will have a panoramic picture!
