Epson Backlit Film is hard to scan without a transparency adapter, but I think this shows the degree
of shift pretty accurately. The center image is the control print. The top one is the result of
the ozone test, the bottom one the UV test. The grayscale in the top print is slightly warmer than the other.
It's especially noticeable in step 3, I think.
The images were scanned in one pass. The scanner is a Microtek E6. All automatic adjustment settings
were disabled.
