My problem is that I don't use flash that often but when I do I seem to blow the faces off of the people that i am photographing.
Example, I want to use the flash just as a fill flash, I just blow the faces out and end up with a very over exposed image.
I have the canon 580 flash (new one) on the canon 5D, i had the flash set at at -1 compensation and the camera was on manual.
Can someone please try and put me on the right track for settings as I have to take some photos tonight at my wifes birthday dinner
