Both images were printed at the same time, on the same piece of Ilford Glossy Paper.
The right print was stored in a ziplock bag, in a dark closet. The other was exposed in my
"ozone chamber" for 14 days. Although it doesn't show here, the grayscale of the ozone exposed print is
very, very slightly warmer than the control sample.
The print on the left got bent and creased during handling. That's the reason for the funny white
mark in the image.
Both images were scanned in one pass. The scanner is a Microtek E6. All automatic adjustment settings
were disabled.
