Ok I am going to strip down to my bare ignorance in public here so no tittering I am blushing already. I am about to take delivery of a Canon Speedlite 430EX MkII and a SB-E1 bracket. Now I know that this flash, through some clever jiggery pokery, will allow me to choose my camera setting and the flash will be set automatically to compensate for any shortfall in lighting....within limits. What I am unsure about is if I want to bounce the flash...how do I determine my camera settings since I will not get the same level of light from the bounce?
