I got bored. Then I found some coloured paper I bought a while ago for a project. Then I started playing with a few sheets, my Canon G7 X and my Rotalight Neo to see what would happen.
These are just the quick test images I was playing with. If I get around to it, I’ll set up a better camera on a tripod, construct some patterns a little more carefully and … probably still use the Neo, because it actually does a pretty good job in a confined space!
