Ok, so there's this guy who wants me to take a pictures of him and his wife for a Christmas card. I was hesitant at first because I have no experience doing this but figured it's worth a shot. So, what I'm looking for here is some advice because I know close to nothing about this. Lighting is probably important, I only have these small lights that came with a lightbox kit, I'll bring them along and see what I can do. I'll try to get even lighting, and expose for their faces? I imaging I'll be going to their house, just try to find a nice place to sit them down/pose and go from there. I'll be shooting with a Rebel XT, and have the choice between a Tamron 28-75 f2.8 and a canon 50m 1.8. Any recs which is better to use? Thanks guys.
