Originally posted by IgorZ I shot Rollei infrared and Aerochrome, and although I have yet to scan Aerochrome, it looks like I didn't mess up too much. So the metering seems doable... But you do need planning for sure. I remember reading a review of Aerochrome and the guy said not to take photos on overcast days. I shot the whole roll (120) in about 40 minutes. There were clouds, but lots of blue sky as well. It seems that when I was taking one of the photos there was no blue sky in the frame, and that sky doesn't look nice at all. Aerochrome is certainly the most expensive film I have shot ($60 CAD). I will wait for the scans to decide if I ever decide to splurge so much on one roll of film again.
yikes, that a lot! Fortunately, Kodak's datasheet on HIE gives some suggested ISOs for different filter types. I think the filter I'm going to end up with is an 89B, which is not pure IR, as it lets a little red through. Kodak suggests metering at ISO 50 for an 89B or ISO 25 for a 87 and ISO 10 for a 87C. Nonetheless, nothing or almost nothing will be visible through the viewfinder (if I'm shooting an SLR.) So a tripod will be necessary: mount the camera, frame the shot, focus, adjust focus with the infrared focusing mark on the lens, meter, set shutter/aperture, attach filter, take the picture (or bracket my shots).
The other odd thing is the warning to load and unload film from the camera in a darkroom. (there is someone on ebay selling a roll of HIE in an old metal film canister. The canister clearly states to open in a darkroom, but of course the seller took the film out for the photo...)
