WHILE USING THE 420 EX FLASH ON THE 20D, IT ALWAYS SEEMS TO BE 1 TO 1.5 F STOPS UNDER EXPOSED. NO MATTER WHAT AUTO FOCUSING I USE OR LIGHT METERING. I CAN CORRECT IT BY ADJUSTING THE COMPENSATION, IS THIS NORMAL FOR THE 20D. i DIDNT SEEM TO HAVE THIS PROBLEM WITH THE 10D.

Mine comes out about 2/3 of a stop under exposed in auto settings but comes out fine if I'm shooting manually. Go figure...

I use a 420EX flash with an EOS 300D. My images are usually around a stop underexposed if I let the camera run the show, but this is generally because I never, ever point the flash *at* what I'm shooting. Bouncy, bouncy, bouncy! The thing is metering as if I had the flash pointed at the subject, hence the underexposure. I really need to learn to use the FEL function, but since I have FEC, I tend to just jack it up a stop in FEC or EV, or else just shoot in full manual. Really the only time I ever shoot in auto mode is when I'm shooting casual family stuff like holiday gatherings, or when I'm doing urban casual/outdoor stuff and don't want to interrupt the flow fooling with exposure settings.

The other thing to watch out for is that the preview, pretty much no matter what brightness you set it to, will look brighter than that actual image. The histogram is your friend, it never lies!

You could check the canon user manuals ( http://www.manualshark.org/b/canon-3/ ) or the canon d20 manual directly ( http://www.manualshark.org/p/canon-3/canon-eos-20d-305/ )

DUH. I found out why I was sometime geting dark areas in my photographs. I wasn't attaching my lens shade correctlly on my 28-70 L lens. If not in the lock possion, the lens shade is wide on the sides and blocks out part of your image.
