Alright so I've just been asked to shoot an former co-workers wedding because they seemed to like my photos when I worked at the local newspaper with them and I'm pretty nervous cause i've never shot one before. What different kind of photos should I take like group shots and whatnot? The wedding is next saturday so any tips would really help. Oh, and don't really have a light setup, just a couple of $20 Vivis that I mount to tripods via sync cords. So yeah, I'd just appreciate some tips!
