reversal films you will use. These standard transparencies will be used to
arrive at standard filter packs for various paper emulsions. To make your
first or test print:
a. Set up the enlarger with the required UV and IR cutoff filters.
b. Place a clean, dust-free transparency removed from its mount into
the enlarger with the transparency's emulsion toward the lens.
transparency to eliminate any stray light from escaping around its edges.
c. Remove all color balancing filters from the enlarger light beam to
give a filter pack designation of 0 cyan, 0 magenta, and 0 yellow.
d. Adjust the enlarger for an 8 x 10 print of a 35mm slide. Set the
lens at f/5.6 and make a series of exposures at 10, 20, and 40 seconds.
e. Process and dry the test print.
f. View the test print and estimate the filter pack and exposure
adjustments required and make another test print at the selected filter
pack, exposure time, and f/stop. Process and dry this test print. Continue
this test printing until you are satisfied with the results.
g. When you are satisfied that the color balance and density are
correct, record the exposure and filter pack information as your "printing
standard" for the type of transparency used as the standard transparency.
Assuming the printing conditions, size of enlargement, and paper emulsion
number remain constant, all other transparencies which are similar to the
standard transparency should produce equally good prints.
h. Use the printing standard you determine for your first standard
transparency to help you arrive at a printing standard for your other
standard transparencies. There is no need to go back to 0, 0, 0 filtration.
Instead, use your first printing standard as the starting point for other
The same viewing conditions which were discussed for
viewing test prints from color negatives are suitable for evaluating
reversal color prints.
However, when comparing a reversal color print to
the transparency from which it was made, the transmission and reflection
