i've been asked to shoot "emergency headshots" for a friends friend. emergency as in we need to shoot them this or next week. i told her i'd do it, but i'm not sure if we should shoot indoors (i have a studio) or if an outdoor location would be better. can anyone give me tips on how to take a great headshot? she is auditioning for an off-broadway show. i do shoot mostly portraits, but headshots are new for me to shoot, so any help at all is appreciated. thanks!
