A while ago I placed a 0 contrast filter behind the pinhole of my 11x14 pinhole camera, in which I use 11x14 Ilford MGIV RC paper for negative material.
It SEEMS to me that the tonal range of the negative improved. However, I am not at all sure of this. I know I could run some test and find out, but was wondering if anybody had a definitive answer.
