When I need to control DoF (events such as weddings), I shoot Av, and tweak the ISO to suit to keep the shutter speed the right ball park as is needed. When I need to control shutter speed (such as sports), Tv. Same thing, keep an eye on aperture and tweak the ISO when needed. I also freely use exposure compensation to suit.
+1, but I will say that Av is much more effective on recent bodies where you can specify a minimum shutter speed, else with a wide angle lens the camera will pick a shutter speed that usually too slow when people are the subject(s).
to be fair, I thought I'd just stir it up a little. what works works.
Well then, allow me to reciprocate. Lots of *cough* experienced photographers use manual because that was a better approach, in those days of yore. What happens with an older camera when you set M mode and Auto ISO? ISO is fixed at 400 - pretty useless. But with our modern conveniences, like a functional Auto ISO in M mode, the ability to specificy a minimum shutter in Av mode, the ability to limit the range for Auto ISO, etc., the automatic modes are much easier to use. Get with the times!
Personally, I shoot Av most of the time, Tv occasionally, M mainly for birds in flight and when shooting with studio flash, and almost always Auto ISO - the full customization of the 1D X allows me to restirct the automatically selected parameters to the range I need for the subject(s) I'm shooting. I like not having to think about the exposure, which the 1D X consistently nails if I want it to, and EC takes care of times when I want something different. But on the much less customizable EOS M, I use M mode with Auto ISO exclusively.
Point is, use the settings you need to get the shots you want. And don't worry about what settings others use...
