OOPS! I'm guessing we've all done something like this before.. I did a quick portrait session over the weekend and in my rush forget to set my shutter speed down to 125. I keep the lens stored at 400 F~5.6, the least used settings, and didn't notice even though I set the aperatures correctly. I was using strobes for the shots and stopping down to f~22 2/3 or so as per my meter readings. Since most of the light is put out in a very short amount of time, did I really lose almost 2 stops on the shots? The film used was TMax 400- should I push it and if so, by how much? If I can get some idea of a starting point, I'll probably develop a sheet or two to see and then do the rest based on the results. Any input is welcome!
