These were taken with a 28mm f/2.8 lens on a Nikormat with a #12 yellow filter.

Hi!

I used a pro/commercial lab for my EIR with no problem. However, I do not know
if it was becasue of the type of machine they have, or if they mounted by
hand. So if you have choices in your area, you may want to call around.

My experience with EIR is to meter at 250 or 320 (if your camera permits) and
bracket about a third, one-half, or one stop around that, depending on how
uncertain I feel about conditions. I found that shots at 200 were often a
little overexposed, while 250 or 320 were right on. But this is in southern
California which appears to receive a fair amount of IR, especially in the
deserts.  Even thought the film is expensive, it probably pays later to do a
test roll of typical conditions in the area where you plan to shoot,
bracketing from 100 to 400 in third or half stops.  Then use whichever setting
seems best for your camera and subject.
