SHORT GUIDE TO PHOTOGRAPHY

A SHORT GUIDE TO PHOTOGRAPHY

Photography can be a rewarding pursuit. It is a broad and disciplined field that can take

years to master. But the pleasure in making photographs and the joy of capturing a

magical moment cannot be compared. The guide is an introduction to some basic

photographic principles.

The lens aperture controls not only

exposure, but also depth of field; the

area between the closest object in

focus and the furthest object in focus.

The larger the aperture value, the

greater the depth of field. The smaller

the aperture value, the shallower the

depth of field. The required shutter

speed for the exposure increases with

the aperture value. Usually landscape

photographs use a large depth of field

(large aperture value) to keep the

foreground and background in focus,

and portraits use a shallow depth of

field (small aperture value) to separate

the subject from the background.

Depth of field also changes with focal

length. The smaller the focal length,

the greater the depth of field; the

longer the focal length, the shallower

the depth of field.
