I shot a family portrait session this last weekend, and they wanted to do it indoors in their basement by their fireplace (wouldn't have been my choice, but whatever...) The whole family was a family of blinkers. I think out of the approximately 100 photos, maybe 10 have all poeple with eyes open. I use the on camera flash to trigger my SB-600 in a soft box, and SB-700 bounced off a large reflector. I think that it must be the pre-flash causing their eyes to start blinking, so by the time the shutter fires their eyes are already closed. Any suggestions to fix this in the future, so I can avoid all of the painful post-work of cutting and pasting eyes?
