DESCRIBE THE TYPES OF COPY FILMS
1.
Film controls picture quality. To produce high quality pictures, you must select the proper film
for the job. In selecting the proper film consider color sensitivity, film speed, and contrast. We will
discuss only black and white film in this section.
2.
Film type and color sensitivity.
a. The many different varieties of film can be reduced to five basic types by their color
sensitivity. The types are nonchromatic, orthochromatic, panchromatic B, panchromatic C, and infrared.
The color sensitivity of each of these types, and of the human eye is shown in Figure 2-1.
