Convestro said “no no don’t use water “?
Because of these bubbles …

Re: Crystallization problems w/ Dip-n-shoot or G307
From what I remember, I had to drop the amount of amdi in the sensitizing bath and also added a bit of soap. I was shooting in green back then so wanted as much dichromate in the film as possible. If your using blue light should work w out crystals , dilute your sensitizing bath a bit..

Hold on here! as the prior made copies come out quite consistent as pictured first, I was present during recording and allowed less than 10 minutes settle time on the one that went rainbow .. plus I can see under laser movement between the two plates . I’ll try and get a movie of it …I think will ex...
Re: Venus
Ok so you see the results, but now the puzzle! In my efforts to fall into a “production mode” Making proximity copies , pushed the settle time and shot this one (motion between H1+H2). What’s happening here to cause this rainbow replay (in reflection),and is mysteriously missing the Blue 488nm it wa...
