The seach function is disabled, so I don't know if this has been asked & answered before. Probably not, because I must be the only who doesn't know this stuff :)
To avoid blownout photos, I use the manual setting as it allows me to underexpose. What I do not seem to have control over in this mode, is the DOF. I'd like to control the aperture, but don't see how to do it when on manual and have the exposure comp set.

You should be able to adjust F#, shutterspeed in manual independently. EV compensation should be accessible in every mode.

i dont think it can be done in full manual mode (i just line the exposure up to the -1 or -2 line)
To do it in Av, Tv or P i know that you can hold down the AE lock button and use the QCD |

I've been doing the same in Manual, but thank you! for the way to control the EV in other modes :)

As long as the switch is set to the mark above ON and you have it set for taking shots on M mode for manual, You should have full control over everything.
I have 20D :-) I always shoot in Manual.

Control of depth of field is through your aperture. You can use aperture priority and exposure compensation to deliberately under expose which is a bit quicker then through manual mode. You cannot use exposure compensation in manual mode.
Now as far as I'm aware if the 20D is like most other Canon cameras, it has a "Depth of Field" mode which I find very handy. This is an auto mode but you can use it to set up focus/aperture and then switch to manual mode to take your photo. It is a slow process but will work fine when your dealing with a subject that is stationary.
First set your camera to Depth of Field mode and take an exposure reading. The way this mode works from model to model varies so read up on how to use it first.
Once you are satisfied that all elements in your image are within the focus range, switch off the autofocus on your lens and do not reset or adjust the focus or move from your position. Take note of what aperture the Depth of Field mode has set the camera at.
Switch over to manual mode and set your aperture to the setting the Depth of Field mode indicated and adjust your shutter speed until you get a correct exposure. Then take the shot.
I find this works very well and you have more control. I find using the depth of field mode to take the shot isn't always very accurate in rendering a good exposure.

In M (manual) mode you can adjust the DoF by adjusting the aperture. For more DoF set the aperture to a higher âfâ number â or f stop - (i.e. f22, f32) by using the thumb wheel on the back of the camera. For less depth of field set the aperture to a smaller âfâ number. To under expose the shot set the shutter speed such that the cameraâs meter indicates -1 (for one shot under exposure) or -2 (for two stops) or where ever you feel is adequate. I say to adjust the shutter speed in this case because it sounds like the DoF is your primary concern next to under exposing the shot to prevent blowing out the highlights.
Hope this helps,
