RE: [APML] Pre-Flash Tech Pan

Mike,
    I can tell you that tech pan does *not* work with a cold camera, in case
you were thinking of trying it. Never tried pre-flashing or H2O2 but my gut
feeling on the pre-flashing is not good. Good luck!

Subject: [APML] Pre-Flash Tech Pan



Hello!  Since commercial Hypered 4x5 Tech Pan is not available, I'll be
using TMax to experiment with my large format camera.  However, I'd like to
give Tech Pan a try, but I am not ready to start gas hypering my own.

 

    I've read about both pre-flashing the film and using H2O2 fume
hypersensitization techniques.  Does anyone have any experience with either
of these with Tech Pan?  Thank you and best regards.

 

Mike
