bouncing flash inside large venues – adding TTL flash to ambient light
One of the ideas that has been mentioned here previously, is when using on-camera flash indoors, to approach it with a studio mind-set where possible. Instead of bouncing flash upwards towards the ceiling, or even simply behind you, the idea is to think “where would I have placed my softbox if this were a studio?”
Then it is simply a matter of pointing the on-camera flash in that direction, and flagging any spill light from the flashgun. I most often use a piece of black foam to flag my on-camera speedlight.
The image at the top is from the bride & groom’s portrait session in a museum. And this is what the ambient light looked at those settings:
(which were 1/125 @ f3.5 @ 1000 ISO for all three these images)
The difference is due to bouncing on-camera flash to my right and 45′ upwards into this area:
(and I used that black foam half-snoot to flag the spill from the flash.)
A little bit of flash will go a long way at the right aperture and ISO combination.
