Terry, What I did for my aperture was open it wide, and back it off 2 stops. What is an aperture that you recommend? Also, I assume that contrast filters should be used with a test print. Is that correct? I'll develop the prints for 3 minuets next time around.
Thomas, this is my print calculator. You expose the print calc for 60 seconds. http://www.bhphotovideo.com/c/produc...tor_Scale.html
Yes, I did compare the two dry. The test print is how I wanted it to be whereas the final print is darker.
