I'm going to be second-shooting a wedding this coming weekend, and I'm curious as to the best method for group shots (e.g. Bridal Party formals, etc). (I have 2 strobes, triggers, stands, and umbrellas) Should I bounce off the umbrellas @ 45 degrees, or would using a bare flash work better? It will be midday, under harsh sun, so the need will be for fill light and softening shadows. Thanks for your input!
