So yesterday i went to a grad ceremony for my brother,
I brought my 75-300 IS lense i sat righth above the grads. this was indoors. The lighting was terrible i couldnt get a good shot for nothing. even zoomed all the way trying to use the light from the stage to get a good shot and nothing, so is there anything i can do in this position or is it one of those thangs that cant be changed.
thanks

Did you have a focusing problem? Because with 20D you can crank up the ISO for low lighting conditions, and with 75-300 I think that you have f/5.6 when fully stretched, so it would give you 1/60 shutter even with the low light, which should be good enough if you have IS turned on and somewhat steady hand.
If focusing was your issue, that could not be helped with the af assist light (far away from the object), you could have tried manual focus, or finding a light bulb or something else at an approximate distance and locking your focus on it before taking a shot.
Just trying to help...

Yea i put it on auto to see what the camera suggested it was 1/60. So i went back up to P. focusing wasnt really an issue so it probbably was teh AF beams i was pretty far away with low light. when the lith on the stage acutally hit there front i was able to get a decent pic but still to dark.
im extremely new at this still trying to learn as much as i can
thanks for you help

That's a notoriously slow lens...especially on the long end and in low light. You have to use a faster shutter than you'd like (1/90 or higher) and have a steady hand for sure. I learned that lesson the hard way, too!
Like someone pointed out, you can use a faster shutter and bump the ISO to 200 or 400..on the 20D it should still be VERY clear.
P.S. your camera doesn't know you're using a slow lens. So when it says 1/60 you have to compensate by switching to Manual mode and increasing the ISO.

iso 1600, Av set at -2.0, aperature wide open? that should be the optimum settings i would thing. i wouldn't put it at 300 unless your lens has constant aperature. i woiuld go 75 with the widest aperature, use the settings i stated above and then be prepared to crop and adjust brightness/contrast later on

First, if you are in a dark room, you need to increase the ISO, maybe 1600 or 3200 so that shutter speeds are increased prevent camera shake. If you have a 75-300mm lens then a decent rule of thumb is to use shutter speeds at least 1/70 sec at 70mm and 1/300 at 300mm. Since you have the IS, you can have about two stops slower shutter speed. However, these shutter speeds might be slow that if a person is moving, you will get blurs from moving subject and not from camera shake. If you had gotten closer and used a shorter lens like the 18-55 at 18mm, then you would be able to use 1/20 sec shutter speeds to prevent camera shake.
Another way to compensate for decrease lighting is to use wider aperature, but your camera's wides aperature is about f4-5.6, which is not considered very wide (e.g. f2.8, f1.8).
Next time, I'd recommend using high ISO to increase your shutter speeds, and then in P mode, you can turn the dial to set an appropriate shutter speed to prevent camera shake.

Troy,
I was in a similar situation, but used my 70-200 IS 2.8, so as someone commented, being able to open aperture makes a huge difference. That said, all these were taken at ISO1600 with the 20D, handheld.
