Response to KONICA Infrared Film

from Brian C. Miller (brian.c.miller@gte.net)
Well, I have finished developing my test rolls of Macophot IR. I haven't printed it or even looked at it through a loupe. I did develop it in Xtol 1+3, 68F.

This film has an antihalation layer, and it works marvelously. While this film is more spectrally sensitive than Ilford, it has far less bloom when overexposed. +3 stops over exposed did not produce any bloom detectable to my eye.

Initial impressions:

The recommended exposure and development will get you in the ball park, no problem. I shot this film with four sets of filters: B+W 090 (Kodak 25), 091 (Kodak 29), 092 (Kodak 70), Tiffen orange (21?), and no filter. Each filter was shot in a series of seven brackets: N, +/-1, +/-2, and +/-3. The +1 bracket looked like a slightly better negative than the N. The +3 bracket held deep shadows, but printing the negative would require much more work.

My developing steps: prewash, developer, stop bath, fixer, hypo clear, wash, LFN wash. The antihalation layer comes out with a wonderful blue-green color, and the hypo clear and subsequent wash also remove some more blueish dye.

Overall so far, I think this is good film. It's kind of slow, but the speed is in the ball park with Ilford.
