I have some really old papers that I use for contact sheets and after finishing those, I decided to print some prints (well larger contacts, really, as i used my multiple Neg carrier and special easel to make 3 neg enlargements on a strip of 11x14 paper cut into thirds. Anyway, I had the anti fog in the developer already and noticed that even at grade 4 my blacks were weak. Was this caused by the benzo you think? Just curious - its expired, but not terribly old ilford mgiv rc paper. Thanks.
