Thank you for all your work! The idea of seeing the monopolist (= FB) guarding all things holographic sends shivers down my spine. So how can we help? What about doing some fundraising? At some point I should probably post periodic backups to archive.org (aka "The Way-Back Machine"). That ...

Sounds interesting, thanks. As for AgX emulsion making I can still point to https://d-i-yscience.blogspot.com/2016/04/holograms-on-wine-glasses-and-glass.html And of course, there is Jon Hilty's beautiful homepage on Lippmann photography (jonhilty.com/lippmannhome). There is an excellent section on ...

Spectral resolutions looks good and the price seems to be OK.

Does anyone have copies they can share of these two elusive papers by Steve Benton? S.A. Benton, "Achromatic Images from White-Light Transmission Holograms," J. Opt. Soc. Am. 68, 1441A (November 1978). S.A. Benton, "Achromatic Holographic Stereograms," J. Opt. Soc. Amer., Vol. 7...

Does anyone use water to apply the film to the glass? Yes, you can do that. In contrast to hydrocarbon solvents etc. water will not interfere with the photopolymer layer.
