I think it works both ways for me, in good and bad ways. Sometimes I get 'a great shot' after I click the shutter, but when I develop and scan and look at it, it's no good.
But then, sometimes as I take a shot I see someone start to change their expression or position (I take a lot of photos of people on stages in dimly lit rooms, they're performing and moving, and shutter speed are low) just as I press the trigger, and think it's wasted. Then when I get home and look at the result, i'm pleasantly surprised and it's the best shot on the roll.
Surely more skill on my part would negate both of those, but I'd rather lose some good shots to have the pleasant surprises than to just have more decent with no surprises.
