Learning Event 1:
DESCRIBE THE BASIC STEPS IN MAKING A PHOTOGRAPHY
1. Photography
is the record of images produced on sensitized material by a
form of radiant
energy - light rays, infrared rays, and x-rays. Light is
the most common
form of radiant energy. A discussion of light is used in
this chapter to
introduce and describe the basic photographic process.
2. There are three basic
steps
in
making
a
photograph:
EXPOSURE,
PROCESSING, and PRINTING.
a. EXPOSURE: Exposure occurs when the camera shutter is tripped,
permitting reflected light from the subject to enter and thereby exposing
the film. A latent (invisible) image of the subject has now been exposed
onto the film's light sensitive coating, the emulsion (fig 1-1).
