M mode exposure

hi

i have a 20d camera, i am trying set the exposure compensation amount i have been playing around for 35 mins now and cant figure it out . it says in the bible press shutter half way the turn the dial while pressing shutter button i am doing this but the camera changes the F numbers what the hell am i doing wrong??? if i set the speed at 60 and f11 how do i set the exposure level ?
cheers

Exposure compensation doesn't exist in M mode. Actually, the concept is meaningless in M. You've already set your exposure at 1/60 and f/11 - if that's not a good exposure, change one of them or change ISO. That's all you can do.

My 30D manual, in the "exposure compensation" section, starts out with:
"1 - Turn the mode dial to any creative zone except <M>"

-js

yes you are right my mistake not reading carefully what an idiot , sorry guys

no question is stupid. That is what the forum is for, so people will help you out.

i'de suggest starting out in Av mode or Tv mode and playing from there. Av personally, since you really need to get aperture down, shutter speed just compliments ISO in making the right aperture setting work under the lighting conditions, at least at first. when in Av, it'll work exactly like the manual says
