I am interested in your ideas concernig calibration of a spot meter. When I firs t started in large format, I assembled the best equipment I could aford, and par t of that was a spot meter from Adorama. I believe it is manufactured by Capitol , and seems to function well. I have only used the meter in my SLR previous to t his. I never calibrated my SLRs meter, and it seems to work well just as it is c alibrated by the manufacturer. In my reading about large format, I am encounteri ng much about calibrating meters, and indeed, this seems to be the thing to do i f one is going to follow the zone system. I attempt to follow a kind of modified zone syestem for color transparency film. I have had good succes with this in 3 5mm, but now want to be able to refine my exposers, as to not wast film. I would like to hear how you have tested and calibrated your meters. I have compared my meter based on the "sunny 16" rule, and found (to my delite and suprise) that i t was spot on, (if you will excuse the pun). I have found that in compareing it to my in-camera meter, it varies a good deal. But, of course my in-camera meter is a center weighted and not a spot meter.
Thanks, Bill
