4x5 IR, Filters...

[klycea@xxxxxxxxxxxxxxxxx (Adam-HALPID Klyce)]

     Hello all,
     
     I have and sometimes use 4x5 IR sheet film with a few different 
     cameras and have never had ambient light leaks due to the material the 
     bellows are made of. Of course, with any photo- sensitive material, 
     cracks and pin holes are going to fog or streak the the film.
     
     Some other cautionary notes do, however, apply:
     
     1, Try to only handle the film with gloves. I can not tell you how 
     many times I have pulled a developed and fixed sheet out into the 
     light with great anticipation; only to find a finger- print the size 
     of a building (at least on the negative;-)).
     
     2, Pull the dark slide evenly and slowly. Many people have reported 
     tiny streaks across their negatives and I, for one, believe that this 
     could be caused by static electricity generated by pulling the dark 
     slide too fast. (this might
     be alleviated  by simply cleaning the film holder carefully with a 
     charged brush - static-master uses polonium and I love the way it 
     pulls dust off of things.)
     
     That's all I have to say about that, for now....
     
     Jan?! I would really appreciate it if you would e-mail me that filter 
     list. Thank you for everything.
     
     -Adam.
