Apologies if this is a too much of a newbie-style question, but I'm worried.
I developed two rolls of Agfa APX 400 in Rodinal (1+50). I used a Zonalpro stop bath and fixer, then washed the film using the Ilford method (5, 10, and 20 agitations with fresh water). When I pulled the film out of the reels and hung them up to dry, they looked stunning! The darks were dark and the lights were light - a lot of contrast! I squeegeed it and let it hang in my shower all day to dry and took it down at night. By then, it seemed like the contrast had died - like the silver had faded!
I'm not sure if it's just a figment of my imagination. I did test the fixer with an Arista Hypo check before fixing, and it passed that test. My question is, am I seeing things, or is this a real effect that I'm seeing on my film? If so, is it just due to the film drying? If it's a problem in my development process, how do I prevent it in the future?
Note: unfortunately, some of the scans from this film are not available, since I just moved and am having to wait to get the Internet hooked up. Hopefully I can show an example soon.
