Am I doing this right? 1) I set up the Sekonic flash meter some distance away. 2) I set the flash (metz 45, sunpack, and the new nikons I have) to auto 3) Pop the flash and read the meter. Probelm is the actual settings are not matching the meter measurement--usually between a stop or 2 slow. I assume this is a function of the thyristor reading the sum of the reflected light and much will depend on the overall reflectivity of the scene. I just want to get a feel for how accurate this mode will be without burning through a few rolls of film on the RB. Is my test functional and realistic?
