I've been using Ilford RC Pearl Finish Muti-Grade and i'm not getting a "look" I want. I see so many great prints that are so contrasty - very black blacks white whites, yet my prints have a "flatness" to them. They just seem so "greyish"/boringly dull. Is it the paper? Filter in the enlarger? Do I need to learn a new paper - fiber type, hogh contrast?
