I shoot trains at night, using big flash set ups. Keep in mind everything is black when I am there. Let's say I took a shot as the train goes by, and then look at the LCD and see the exposure wasn't quite right or the lighting uneven. Can I simply make adjustments and ask the train to back up and run past me again? No, it has to be perfect the first time. In that regard, it doesn't matter so much if I shoot with my Nikon D7100 or my Rolleiflex.
