I'm making my annual trip to the upcoming world cup track cycling competition and am looking for some new ideas. I've got the technique off pat for panned shots but it's all a bit samey. Thought about taking my Canon G12 and Vivitar 285HV along to try some high sync speed flash. Gear otherwise 5D, 40D, 15mm fisheye and a range of (true) focal lengths of 19-200. The Vivitar and 580EX flashes and a pair of slaved 430EZs. Any suggestions to create something artier?
