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.
