Alright, I'm going to be doing my first real low-light shoot at a high school homecoming dance. I'm going to be using my 1D2 and 70-200 f/2.8 IS for the most part. I'm going to be shooting the dj, who is my girlfriend's brother. I'm not sure if I'll be able to use my 580EX II, but I want to be prepared for the worst.
I know some of the basics like use a relatively large aperture, use a tripod if able, but besides that...I'm drawing a blank.
I've never shot in low-light, so what advice can you give?
My 1D2 isn't the greatest with noise, so what can I do to keep the ISO relatively low?
What mode would you suggest shooting in?
I'm thinking about getting a Canon 15mm fisheye to add some effect, yes or no?
But just in case, say that I can use my flash...any advice there?
