Both images were printed at the same time, on the same piece of Epson Premium Glossy Photo Paper.
The bottom print was stored in a ziplock bag, in a dark
closet. The one on top was exposed in my "ozone chamber" for 7 days. You can clearly see the orange shift
in the gray scale, but other colors are affected, too. Look at the blue squares, in particular.
The images were scanned in one pass. The scanner is a Microtek E6. All automatic adjustment settings
were disabled. Note that my scanner doesn't seem to handle orange/brown colors very well. The effect is
actually much more noticeable to the naked eye than it is on the scanned image.
