Beautiful, how did you do this?
Thank you, Anthony.
What you are seeing in the image are: a brown (not white) chicken egg, a piece of kitchen paper of the towel-like texture and a clear glass bottle.
I happened to find that the brown egg looks strongly saturated red under the 365nm UV flashlight with the Baader U filter. So, I put it on the kitchen paper and added a bottle to make the image more like the traditional still life oil paint. The image was shot in total darkness, and the only light source was the UV flashlight with the filter. There was very faint visible light leak which cast the shadow of the egg. The kitchen towel fluoresced in faint blue. During the process, I just raised the exposure a bit and trimmed the frame. So, there was no significant manipulation.
The camera is Sigma fp and the lens is CRT Nikkor 55/1.2 shot at f2.0.
