tomorrow will be my first attempt at shooting in a reception type atmosphere...no formal shots or anything, just a general reception. I want to use this as a learning experience and really to get my feet wet in mass people shooting environments... tips? pointers? methods? I'm especially interested in hearing from those of you in wedding photography. I'm taking a light look into turning it into a side business. I get approached fairly frequently and turn everything down, but it's becoming more and more obvious that this camera gear needs to start earning it's keep. thanks!
