I am still relatively new to this home processing game, having been processing for only 6 months or so. Everything I have done has pretty much been by the book. I have been using Ilford products, both with film and with developers.
If I wanted to introduce a bit more contrast with my negs, what would be the best approach? Should I be trying to do it in camera with different filters (I have been using a red quite a bit, but need to get some others)?
If I wanted to do it at the developing stage, what would be the best approach? If I were to increase development times, should I increase by 10% or 50% (to use some broad figures). At the moment, I am using ID-11 and Delta400
