Chavez Film God Posts: 2153 From: Martinez, CA USA Registered: Aug 2003 posted 04-29-2018 09:40 AM                       Whatever it is and I don't know, I've seen prints where it took years to show up, almost like rust popping up on a seemingly perfect chrome bumper. It seems to come from within.  |  IP: Logged Randy Stankey Film God Posts: 6539 From: Erie, Pennsylvania Registered: Jun 99 posted 04-29-2018 10:31 AM                     My guess is "processing spatter" like Gordon says but also combined with poor washing. I see effects like this, occasionally, when I make photo prints in my darkroom and don't wash them long enough to get all the residual chemicals out. I have a really nice photo of some Civil War reenactors posing for a faux-historical group photo. I had a Civil War historian look the image over to find any historical inaccuracies and he said it was "clean" except for a couple of very minor things. I entered the photo in a local contest and won first place. After that, I put the photo in storage and I didn't look at it for a couple-few years. Last week, I got that photo out to look at it and I noticed brown spots! Damn! I THOUGHT that I washed the print clean enough! Turns out that I DID wash the print well enough when I developed it but I also sepia toned the print using a sodium sulfide (rotten egg) process. Even though I washed the print for over an hour after developing, I only washed it for 30 minutes after toning was completed. I thought that would be enough to get all the residuals out but...I guess not. Since it's supposed to be a faux-historical photo, I guess the spots add to the theme but, dammit! I wanted that photo to last! Anyhow... The spots on that piece of film Brad showed reminded me of the spots on the photo I made.  |  IP: Logged
