Guy,
Don't be silly. Figure your own printing time.
The following works for any materials,
processing, and situation.
+ Develop an unexposed piece of film as typical.
+ Make a print, test strip. (expose various
times with that negative)
+ Determine the exposure that gives "maximum"
black.
+ You have found the printing time for those
materials, development, and processing. You may
wish to deviate from this "typical" exposure,
but this will be the best starting point.
Note: Use the printing method and materials that
are typical, because results will vary for
differing methods and materials.
Note: The "maximum" black is not the maximum
density possible with the materials. An
exposure in which it is thought that there is a
distinction between "maximum" black and maximum
black is close to the proper exposure.
CAUTION: Do not use anyone's suggested times.
Determine your own.
