Please forgive what must seem an unbearably stupid question: The common wisdom is that, when enlarging, cold-light sources give softer results than condenser light sources, so that a negative that needs a #2 filter when printed with a condenser head onto VC paper will need a #3 filter with a cold-light diffusion head. Does this apply also to graded papers? I have negatives that I print with a cold light head that need a Grade 4 paper. If I print them with a condenser light source, can I get by with a Grade 3 paper? I'm assuming it doesn't work that way, but please, someone give it to me straight. Sanders.
