O List (with apologies if it's a dumb question) -- Here's a hypothetical situation: I want to shoot some waterfalls and other moving water using ISO 50 transparency film, and want to slow the shutter speed to get a nice blur on the water. Conventional wisdom says an ND filter (assume a 2-stop) is how this is done.
So does one meter the scene before or after the ND is in place, i.e., adjust exposure for the desired medium tone, put the filter in place, and then slow the shutter by 2 stops? Or simply meter through the filter and use the desired shutter speed (1/4 to 1/2 sec?) as a baseline for adjustment? Any hints or tips would be appreciated. Thanks in advance, Stephen Moore
