Yesterday I was trying out various things to get the bounce flash working, mostly compensations. Nothing helped. I happened to try bounce flash with the built-in diffuser covering the flash, and it worked like a dream. Very natural looking exposures. My theory is that the bounce was zoomed in too much to hit the subject.
