I calibrate my EM-10 and paper as follows:
- Use a grayscale in the negative holder (6x6) then measure the
Em10 setting for 2 or 3 stops. Then print a test with the Kodak
Wedge and determine exposure for zone 1, 5 and 8
After that since I had made a table of +- stops I can determine
the times required to generate any gray tone for the paper.
