First of all, keep in mind that paper negatives are NOT film negatives. Paper negatives produce a different "look" in
photographs. Photographs produced with paper negatives appear higher in contrast, more compressed in tonal range,
and less sharp than photographs produced with film negatives. Double-weight multicontrast rc paper works fine. I rate
the paper at ISO 8 and develop in Dektol 1:2 at 68 degrees for 1-1.5 minutes. To control contrast, you can pre-flash the
photographic paper used for the negative. Google "Ilford and pre-flashing paper" for details on the process.
