I've often seen photographers shooting OUTDOORS with a piece of white
card stuck to the top of their flash, and the flash angled up a bit.
Am I correct in assuming that they are using fill flash? Is this a
good quick-fix technique? What's the best angle for the flash?
Wasting batteries. I don't know why people are afraid to use flash (direct) when using fill flash (outdoors). If you use it correctly with the right FEC....the light is/can be very pleasing. No 'harsh deer caught in head light look'. Use AV mode and dial down your FEC -2/3 up to -2 if necessary. Watch your shutter speed (depending on your ambient light). If too fast, dial down your ISO and if necessary switch your ext flash to Hi-sync.
By using a card-board/card outdoors....you are wasting a lot of light unnecessarily.
But I can occasionally see the advantage in using a card/a betterbounce card/joe demb flip-it in an outdoor setting. This situation is usually at dusk or night outdoor setting. Av mode is almost too difficult to use in this scenario. So switch to M mode and in this situation...by all means...you don't want the full blown light from your direct flash to light up your subject, so bouncing some light to your subject with a card may be useful.
I have a 430 EX and 30D. Do I shoot in AV mode to emulate this? Any
need to adjust exposure compensation on the flash?
As above.
Also, any tips on doing the same thing INDOORS (assuming I don't have
a nice ceiling to bounce off). I've read that I should:
- set an aperture for desired DOF,
- a shutter speed between 1/60-1/250th,
- set + 1/3 to 2/3 flash exposure compensation,
- shoot 400 ISO to allow for faster flash recycling
Bounce, bounce, bounce. The only time you can't bounce is when the room has BLACK walls and ceiling. Shoot RAW and bounce off anything you can. Correct the WB in post processing. Ceilings are not the only thing you can bounce off. Take advantage of white walls.
Use:
M mode.
Shutter speed based on your ambient lighting....1/10 to 1/125
Aperture would be relative (but in extreme situation...may need to still shoot relatively wide) pending on ambient light.
For boucing...yes, FEC +1/3-2/3. But I have read that iwth the 40d...one does not need to compensate?!
And yes about the ISO.

These are just guides....with flash photography...you could create whatever light you want to get the desired effect (the beauty of flash photography).
