Look out behind you!!!
Now I'm not just saying to look out for the obvious, your buddies doing the peace sign over your head, but what's in back ground can really take away from what you want people to see and hear. you could be taking about the cure for cancer with all heart felt sincerity. but if there's a picture of a girl in a bikini behind you, guess what people are going to notice. Make sure there's nothing behind you that could distract your audience. Or better yet put some thing in the back ground to reinforce what your saying. also be aware of contrast, if your sitting in front of a window on a sunny day your going to be completely in the dark. The best bet is do a test run and take a good look at the pictue.
See you later
