Hi all

I have a Canon EOS 10D and recently purchased a speedlite 550EX flash with it. When I use it on AV the camera seems to expose for the ambient lighting..i

When using the 550ex can some one advise what settings I should use on the camera in order to ensure I have sharp and crisp images.

the 550ex is an TTL flash and will adjust its flash output to mach your settings. I generally shoot in manual mode with my expsure set to 1/60s to 1/125s and then let the flash adjust to fill the area. I also shoot with the slowest and widest setting I can afford so that I can get as much ambiant light in.
