Digital Cameras & images...

D

igital images are formed from tiny dots of color. The dots, usu-

ally many millions per image, are so small and close together they

blend into the smooth continuous tones we’re so familiar with

from film. These images are captured directly with digital cameras,

or by scanning a transparency, negative, or print. The end result is an image

in a universally recognized format that can be easily manipulated, distrib-

uted, and used. This digital format for images, and the development of the In-

ternet in particular, have opened exciting new vistas for photography which

we’ll explore in this text. To begin, we first look at digital cameras and digital

images. This chapter lays the foundation for your understanding of digital

photography.
