    Sheet Film Development By Inspection With Night Vision Technology

    I have completed building my kit to develop 8x10 sheet film using night vision technology.

    Parts:
    1 - Viper Nightvision monocular or similar (ebay $240 US when I got mine)
    2 - 1 LED Infrared lightbank which is out of range of your films spectral sensitivity (ebay $20 or so)
    3 - 12v powersupply for the LED IR light bank ($10)
    4 - Piece of diffusion material (I used part of an old light box)
    5 - A clear glass tray to hold the film and chem
    6 - Cardboard box around 12 inches high (i found it gave more even illumination to have some distance from the IR light array)

    [COLOR=Red]*warning* do not look into the Infrared LED light bank with the naked eye, I was told eventhough you can not see any light it can still damage the eye, so be careful*[/COLOR]

    The end result...

    With the Infrared Light table and monocular, you have the ability to view your negative on a lightbox as it develops, and without fogging the film. My first test was just using a pre-dev'd neg to prove the concept, and the lightbox was bright, and I could see all detail on the neg clearly. I'll be having a real session with the setup the first week of january and will post back. I have attached a few pics..

    There`s an interesting thread on the AZO Forum about this very IR DBI procedure. You may want to check it out. A lot of people use the head set monocular or binocular systems. I may well go for either or as my DBI with green safelight is yielding mixed results. IR certainly works well for many people. Good luck with your intersting set up.

    What a great idea. You'll work in complete darkness adn yet be able to see perfectly fine. Let us know how it works?.. it sounds like a worth while investment in night vision gear.
    Anyone can make a Digital print, but only a photographer can make a photograph.

    Many modern videocameras have a "night" position which is actually an infrared sensor. Could this be used too? Many people already posess a videocamera.

    there would still be light coming from the video display. How would you solve that?

    Sean, I developed another 6 negs last night with mine and it was great. I then loaded 34 sheets of film and the NV made it SO easy and stopped me from making a mistake or two also.

    I'm doing mine with the built-in IR emitter and had no troubles at all.
    Let's see what I've got in the magic trash can for Mateo!
