Photography
Behind the Lens
As a means of visual communication and expression, photography has
distinct aesthetic capabilities. In order to understand them, one must
first understand the characteristics of the process itself. One of the
most important characteristics is immediacy. Usually, but not
necessarily, the image that is recorded is formed by a lens in a camera.
Upon exposure to the light forming the image, the sensitive material
undergoes changes in its structure, a latent (but reversed) image
usually called a negative is formed, and the image becomes visible by
development and permanent by fixing with sodium thiosulfate, called
“hypo.” With modern materials, the processing may take place immediately
or may be delayed for weeks or months.
