YEAY good advice and it makes sense. I will be taking my 580 EX out and practice a lot. I wonder if I'd look silly at the public park, taking photos of a blow up doll. The weather man says Friday is our last of sun, then the clouds and even some showers will roll in. That might be good for lighting though.

Thanks for this David, I think if I can get comfortable with the flash it will be easier to know the best way to use it in each lighting situation.
