Latent image fading
Posted: Mon Mar 30, 2020 10:36 am
Does anyone here have any data (or can point to any research) about latent image fading?
I read somewhere on the internet (APUG, perhaps, can't remember) that latent images on film/paper fade over time if you wait to process them. I convinced myself that I saw latent image fading in my larger format paper negatives, so I always process them the same day I expose them. Then a month or so ago, I tried a test for latent image fading on Arista Ortho Litho and didn't see any fading, even after the film sat for two weeks. Admittedly, I had some chemistry problems on the litho test, so any change would have to be pretty severe for me to notice.
Does latent image fading really exist? Or, is it like much technical photographic information on the internet, completely taken out of context and/or wrong?
Also, hope you're all getting some good darkroom time with most of us being asked to stay at home to avoid COVID-19.
