#2. "RE: TTL-BL and Tilt Flash Head w/ White Card" In response to In response to 0 Fri 12-Apr-13 06:29 PM by mkbee1
Afaik,you are correct. I use my SB 600 regularly with a large bounce card made from a cut-off window blind, or a pocket bouncer, which loses about 1-1 1/2 stops of light, but the BL feature seems to work fine.
Using the built-in bounce card automatically switches the zoom head angle on my 600 to 14 degrees, which also lowers the ultimate range of the flash.
My favorite use is to deploy the built-in card about 1 inch, just before it flops to cover the flash head, which lets those raging photons bounce against the ceiling, but provides a bit of fill for the shadows caused by the bounce.
I don't regularly use the compensation...how does that work for you?
