Hey all, I've done quite a bit of work with Kodak HIE before, and I've sort of got it all down pat with a #25 Red filter. However I just bought a Hoya RM-72 which cuts of at 720nm (IR) rather than in the middle of the red spectrum so that I may try my luck with a digital camera. Anyway I guess you can see where this is going. I could use the IR filter with the HIE. I've had great success with with the #25 Red when I set the Kodak HIE to ISO260 and bracketing up and down 1 stop, but I wouldn't know where to start now with the new RM-72 filter. Does anyone here have a good starting ISO to pick for the RM-72 filter? Also the camera I'm using is a Nikon FE with a rather ancient centre weighted metre. Is this sensitive to IR light or will I need to meter first and then lock the camera on manual, screw on the filter and go? I ask this because the meter display isn't backlit on the FE. Once the IR filter goes on I won't be able to see the camera meter anymore. Any tips so I'm not all the way back at square one?
