I posed this question in the wedding forum as part of a more general discussion, but it really belongs here. I'm trying to minimize the gear I have to bring and setup in multiple places. I'm the primary shooter at this wedding. Ceremony and group/family shots will be outside (weather permitting). The reception will move inside (same location). I will definitely need to setup a couple of strobes inside for better lighting. But this question has to do with the outdoor group shots. I'll setup somewhere with a scenic backdrop, where the sun makes a nice hair and accent light. I'll be shooting mid to late afternoon and expect there to be decent ambient light. So I'll just need something to fill shadows, but I'll be shooting groups of 2-3 to much larger groups. Easiest thing, if it would work and provide enough power, would be to use my 580EX off-camera for fill. I could leave the strobes setup inside, and ETTL would help with changing lighting conditions outside. However, I suspect it won't provide enough power for larger groups, and I'm not sure which modifier to use with it (I can use any Elinchrom modifier with the Kacey Elinchrom adapter). If a strobe is called for outside, I can certainly do that. Just means lugging more stuff and moving it. If I use a 600RX for this, which modifier would work best in an outdoor setting to cover various size groups? Thanks.
