Photography can be a rewarding pursuit. This guide is an introduction to some basic photographic

principles.

The zoom lens does not only affect how large the subject is in the picture, but it also influences the

depth of field and perspective. Depth of field is the area between the closest object in focus and the

furthest object in focus. As the lens zooms in (telephoto position) to the subject, the depth of field

becomes shallower, separating the subject from the background. Many portraits are taken with

telephoto lenses. Zooming the lens out to the wide-angle position makes both the foreground and

background appear sharper. Usually

landscape photographs take advantage

of the large depth of field of wide-angle

lenses.

Wide-angle lenses also create a strong

perspective which gives a sense of depth in

the image. Telephoto lenses compress the

space between the subject and background

and create a weak perspective.
