Just as the title says, how do I accurately calibrate\determine the accuracy of a light meter.
I have a Weston Master II and I know I can set the zero point from the back, but how will I know that the number of foot candles it reports is accurate?
I can compare it to other cameras, but when I do that on the Rebel 2000 I get the same result and a different on the AE-1. So, I don't think that is a good answer.
