    I just received a used Minit Mask (A/N glass, raised center for 35mm). It doesn't seem to form any contrast mask image or exhibit any density change, even after clearing it numerous times with a heat gun and popping it with multiple flash bursts.

    Anyone have any tricks for reactivating these, or do they just go kaput after so many years? Thanks in advance...

    Photochromic materials are typically changed by exposure to UV and will stabilize over time, meaning they will stop changing. The more often you use them, the faster they stabilize.

    Chris - you keep surprising me, with your research, Bob Pace was a great master of photo comp, not the best but good, I can see now where you are going with your questions on masking on the other site.

    Are you going to end up at Ryerson next year?, I did not see you this fall, where are you taking all this info gathering?
    You cannot be doing this all at work , are you planning to make some prints? If you go to Ryerson, I can give you some access to my darkroom for practical testing, I am not sure the school has the equipment that you will need to work with from all the info cramming you are doing in your head.

    Hey Bob,

    That's exceptionally generous of you. Yeah, sorry I didn't make it out to you and your offer of darkroom space is actually an amazing boon. If I do go there, I will definitely take you up on that. I'm still figuring all that out... some big decisions.

    The internet allows research at lightning fast speeds, and immediate posting of queries, questions, etc. You might be surprised how little time it takes me. I just keeping following the rabbit hole... :wink:
