more tips on Photography

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.

One has to be very careful when handling a camera, otherwise you can leave fingerprints on the opics of it. The problem with fingerprints on the optics is that your pictures won’t turn out as clear in some parts as they could. In order for peak performance, and clear pictures, make sure you clean your camera all over reguarly with the right cloth and solution. Not all cleaning products work on the optics, such as tissue paper, fingers, saliva, or household cleaning solutions. Only use what you can get at a camera store.

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.

One aspect of taking a pleasing photograph is depth of field. When you look at a picture, you will notice that all the area surrounding the focused subject is also focused. This area is called depth of field. In order to change the way the depth of field in a picture is seen, focused, and lit, you must change the width of your lens. The wider the lens is, the smaller the depth of field will be. To decrease the depth of field you can also move closer to your subject. To increase it, you can use a smaller lens or move further away from your subject.

Landscapes are the opposite end of portraits in the sense that you mostly want all the picture to be in focus. To achieve this effect, use as small a f/stop as your camera allows, say f/16. The smaller the f/stop, the greater the depth of field achieved, and objects near and far will be in focus (again, with consumer digital cameras and the short focal lengths of their lenses, good depth of field is achieved even with ‘large’ f/stop). You could use the Law of Thirds to capture 1/3 land and 2/3 sky, or the other way round, 2/3 land and 1/3 sky. You would surely want to use a wide-angle lens setting. Adding a foreground object might help achieve a sense of three dimensionality. If water is involved, a slow shutter speed will give the impression of flowing water. If the sea is involved, a polarizing filter will cut glare and give the ‘transparent’ water effect.

The panoramic picture is a new and exciting mode that is becoming more prevalent in digital cameras. Start by setting your camera on the tripod and ensure that it can only swivel left and right and not up and down. Take your first shot. Note the edges of the picture carefully and identify where you want to overlap the next picture. Choose an object where the overlap will be less apparent. Then, without moving the tripod to another spot, swivel the camera, say clockwise, and take your second shot making sure you have overlapped a part of your first shot. Continue to swivel and take shots until you have captured everything you wanted to. Then use the software provided with your camera to “stitch” the shots together to form your panoramic picture. If done properly, panoramic pictures (landscapes and group pictures) can be very impressive. Note that best alignment results are obtained from cameras with the tripod socket smack under the lens.
