Re: First Light with Integraf Kit
Yeah, I'd love to take a weekend to visit the guys in Miami, but Florida still has over 100 people dying a day from COVID19 and our Governor is essentially lifting all restrictions and opening the state up. So no field trips for the foreseeable future, I'm afraid. I think I'm going to finish out the...

Re: First Light with Integraf Kit
The card did the trick. The dry erase works well to block the edge for the replay.
And good call, jrburns47, I bought some chemicals off of Phogorapher's Formulary and made up some new developer.

Re: First Light with Integraf Kit
Thanks. I've been trying tommyNaN's suggestion of using dry erase on the edge. That makes it a little better, but doesn't seem to be enough. I think I'll try electrical tape next time.

Removing Emulsion from PFG-01 Plates
Is there an easy way to remove emulsion from the plates? I'd like to resuse the glass from old or failed holograms and reuse them for other purposes.

Re: First Light with Integraf Kit
Excellent idea. It turns out that 6 pack boxes for cans are very close to that--roughly 12 x 13 x 20 cm. I just happened to have one of those around... weird! https://imgur.com/I2XLkuq.jpg I used clear acrylic paint to cover the inside with left-over wrappers from the plates. https://imgur.com/Cv7tK...

Re: First Light with Integraf Kit
https://i.imgur.com/ufcLllQ.png Exposure test. 1s and 2s didn't appear to hit the threshold. They also didn't get very dark in the developer. I did some very rough estimates (no power meter) and determined my power density was something like 10-20 uW/cm^2 which would put optimum exposure around 4-8...

Re: First Light with Integraf Kit
Nice. You guys rock. Thanks for the excellent information. From the wiki on CWC2: Follow with a ... 'Chrome bleach for change of replay wavelength in the reflection mode. Does "Chrome bleach" mean bleach with potassium dichromate? If so, it sounds like that's what happened. However, lookin...
