First try with Rheinberg illumination

#1 Post by smollerthings » Mon Sep 20, 2021 1:33 pm

With my favorite stentor as a model.
I really love the colors but I think my iphone is having a bit of trouble with noise in this relatively dark environment. And youtube is way over-compressing the video.

Looks great. Is this printed on transparency or are you using some kind of photographic gel? Or perhaps plastic discs?

Thanks guys.

It is a inkjet transparency paper on which I painted with some blue paint I had. Not great because the blue paint cracks at some spot et let in a lot of light. Seems ok now that I have more layers on.

What are other methods? I have a laser color printer, would that be better?

Best is if you can construct it out if something transparent that doesn't diffuse the light (at least the center bit) like a photography gel or colored plastic. Printed Rheinberg patches tend to diffuse the light, causing mixing of the two colors that reduces the effect and also reduces (I suppose) the effective numerical aperture of the system (which reduces resolution).
