Brushing up on whatever portait info I can find on the web, but it won't hurt to ask here.
Tomorrow I am shooting a group of prom students. It will be daylight, outdoors. My eq is the digital rebel xt, the efs 17-55mm, I have in my hands a circular polarizer as my only filter option. Will have to locate my tripod.
Any tips on shooting portraits? Tech specs and artistic ideas.
