Response to Splotches on Infrared 5x4 film

Hi All,

Update (Problem solved)

I've just processed another pair of infrared negs of the same scene, this time without any problem.

The only two things I did were agitation and film holder. Agitation -- just took a bit more care this time, though I don't think I was being particularly sloppy the last time. I used an almost new Fidelity holder (used twice previously by myself), with plastic frame and plastic slide. I am of the opinion that it was indeed the pressure plate on my first holder that caused the problem, as I can just about make out imperfections when held obliquely to the light.

Thanks for the suggestions, all!
