I have just developed the loveliest negatives, using Pyro for the first time. No streaks or unevenness whatsoever! However, the color of the negatives puzzles me--they are an olive green (APX 100 and HP4). Is this normal? Also, I used Kodak Rapid Fix without part B hardener, but read that Photographers Formulary TF-4 is better. Why is this so?(posted 9146 days ago)
