I'm a newbie and want to get faster shutter speeds when using my 430 ex speedlite on my canon rebel XT. So far "P" is the only one that seems to not take into account ambient light, and has a constant shutter of 60. (Of course the background is dark and the pics look washed out). As I understand "Av" "Tv" and "M" all take into account ambient light, which makes the picture look good, but slows the shutter WAY down. The other things I've tried are: 1) adjusting ISO WAY up which makes more noise and, 2) adjusting the custom function #3 which forces "Av" to have a shutter speed at 200. But this doesn't seem to yield very good results - colors look washed out again like in P.
Is there a way to get a 125 shutter speed without taking into account ambient lighting or do I have to live with slow shutter speeds?
