I'm doing comp card photos for a friend's relative (12) tomorrow afternoon as a favor (i.e. pro bono, i.e. free). I've been in e-mail & phone contact with the mom. Sorry this is not a specific question, but I'm worried that I'm missing some tips or advice that I may regret after the shoot, so I'm trying to see if anyone has general or specific advice on this. I will be shooting at their house. I haven't seen it yet, but from what I've heard there is plenty of nice scenery. I set the time for 4 p.m. for (hopefully) good natural lighting. I plan on bringing the 85mm and Bogen tripod for the headshot. I have a large white piece of foamcore to use as a reflector with window light but what about a backdrop? Also, one idea for a comp card photo was the young lady riding her bike. I haven't really done panning in a long time. What shutter speed should I be using? Thanks in advance. Sorry for the long post.
