I tend to shoot, so far, my IR shots with the R72 fillter, at somewere around F 4 and shutter of 1/30 or 1/20.
This gives me a histo with mostly midrange pixels, say from 50/60 to 180 plus or minus. If i try and get a good mountain histo 0 to 240 or as close as possible, the shot looks horribly over exposed. This would be in the F4 and 1/4 second range. What should i be looking for here. I seem to have ~some~ decent results with method 1, and my GFM photo was using these values. Is it because the filter is cutting out a large amount of the visible lihght that i'm getting the mid range mountain as aposed to the overall mountain histo. Is the midrange histo giving me the proper exposure, even though it looks wrong as in normal colour shots.
