Regardless of the many variables encountered in exposure and
processing, the Cameraman's 12-Step Guide helps produce line
negatives of consistent quality, density and line fidelity. After
development it tells upon inspection whether line negatives are up
to a given standard, and if not, how much correction should be made.
Screening the guide with halftones lets the user evaluate highlight,
mid-tone, and shadow dots from discreet values of gray, and
indicates what adjustments to make to get the detail desired. Two
crosshatch patterns (50 and 250-line) serve as a check for accurate
focus and resolution. |

The Cameraman's 12-Step Guide is designed primarily for copy camera
use. Like other Stouffer Reflection Step Tablets, it can also be
used for scanning, densitometry, and other quality control
applications. The list below contains the most commonly used step
tablets.
