I've been reading for the last 3 hours on the concept of NightVision DBI (develop by inspection). There are a number of posts on APUG and also on the AZO forums about it and I'm almost convinced. Here's a short summary of my findings: It seems that most people agree to purchase a monocular style Night vision unit. One specifically mentioned often is the ATN Viper which goes for $240 on ebay. Also in my findings, most people seem to turn off the IR projection LED to prevent fogging and reflection issues and purchase an external IR LED bank with 50 to 140 LEDs. I've also read that most of these LEDs are about 850nm. This leads me to my question: I came across a few people that complained about fogging at 850nm. Specifically with fuji acros film. One guy did a 30 second exposure test on unexposed film (which seems mindblowing considering development times can reach 8+ minutes). Can anyone elaborate on experiences with fogging. Specifically those using the clear tray IR lightbox technique? I shoot Delta 100 and Tri-X 320. I was thinking of purchasing 950nm LEDs which apparently put out no visible red light. If anyone is interested HERE is a link to a thread where guy who made an IR lightbox to develop with a clear tray on top of it. Sorry for the long post, in short I want to hear experiences, especially tips on preventing fogging.
