Hello. I've been creating paper negatives in a homemade camera. (It's a box fitted with a simple optic; it's not a pinhole camera.) The negatives are very contrasty. I use Ilford multigrade paper. I'm wondering, do you think if I place an 00 filter (or similar) in front of the lens, that I'll get less contrast? Will I have to expose the paper longer? I'm willing to do some strip tests, but I'm almost out of paper, so I'm trying do as much research as I can up front. Thanks.
