JUDGING NEGATIVE EXPOSURE

You can check the exposure level with a suitable electronic densitometer equipped with a filter such as a KODAK WRATTEN Gelatin Filter No. 92 or the red filter for Status M densitometry. Depending on the subject and the light source used for exposure, a normally exposed and processed color negative measured through the red filter should have the approximate densities listed below.

Area MeasuredDensity Reading
The KODAK Gray Card (gray side), receiving the same illumination as the subject
0.75 to 0.95
The lightest step (darkest in negative) of a KODAK Paper Gray Scale receiving the same illumination as the subject
1.10 to 1.30
The highest diffuse density on a normally lighted forehead
--light complexion
--dark complexion
1.00 to 1.30
0.85 to 1.20

Because of the extreme range in skin color, use these red density values for a normally lighted forehead only as a guide. For best results, use a KODAK Gray Card (gray side).
