Originally posted by Hey Elwood I haven't had much luck getting the correct exposures with my k20d and it gets frustrating when I try to take pictures out of Auto mode and get either over exposed or under exposed shots.
Personally, I've found Auto mode to be quite a useful teacher. Take a photo in fully automatic mode then look at what the camera decided to do. If you think any of the settings should be different, try your preferred settings and see how the image changes. Review and compare. After a while, you'll learn how to anticipate the camera--and later to improve upon the camera. That said, I know nothing about flash photography, so maybe this doesn't apply.
Sometimes, though, there's no substitute for automation. Things change too quickly for the photographer to think them through. There's no shame in using automatic features.
Specific feedback: you were shooting at f/2.8, while your friend was shooting with an f/3.5-5.6 lens. His larger DOF probably helped him achieve "better" focus. I'm not sure yours were out of focus more than that the DOF was too thin.
Hope you're enjoying your camera more now. Cheers!
