Re: Which chemistry for "HOLOFILM 250 PAR" from Applied Holographics PLC ?

I did use it with a He-Ne, shooting some transmission holograms. I developed it with an Ilford liquid concentrate, Phenisol, which is their version of Kodak D-19. So I don't think you should have any problems.

Re: Beginner noob to the core

Sure, if you have a pulsed laser! Check out:http://edweslystudio.com/HoloArt/21stCP ... ulsed.html

An alternate route is via holographic stereograms, which I am sure the experts here will explain to you.
