All 3 images were printed at the same time, on the same piece of Ilford Glossy Film beta paper.
The middle print was stored in a ziplock bag, in a dark closet. One of the others was exposed in my
"ozone chamber" for 14 days, the other in the "UV" test. I can't tell them apart. You can see a little
bit of the magenta cast in the gray scale.
The images were scanned in one pass. The scanner is a Microtek E6. All automatic adjustment settings
were disabled.
