Using my 430ex at a fashion show?

Hi, my brother is an aspiring model(?sp) and is to be in a fashion show on Friday. My gear that I will be taking is my XTi, 50 1.4, and my 430ex. Any advice on getting good pics. I don't think I will be able to use a tripod so I'm worried about camera shake. Any advice would be appreciated.

I'm no expert but here is my 2cents.
- Unless he's standing still use AI Servo to keep him in focus.
- Check with the host of the show to see if a flash can be used. As monopod may be allowed.
- Keep the 18-55 on hand, you may find that static 50mm focal length limiting if the models walk to you and away. Getting a full length shot with 50 needs some distance between you and the subject.
- Custom white balance if you can. Save you post processing time.
-TAKE TEST SHOTS, even if it's shots of people setting up the walkway. It will give you a moving subject in most likely the same lighting as the show.

Good luck and post pics when ur done.

Location location location. Set up near an area where the model will be stopping, turning, posing, etc. When the subject stops moving, your sharpest shots will occur.
