Someone was asking me about shooting their engagement party and I've never done a gig b4 ..... it will be about an hour from my house and will be around 4 hours. I figured 300 isn't asking too much. For 300 ill take up to 16 gigs of photos and supply him with an edited version of all photos including original raw files and unedited jpeg copies. I think two 8 gig cards is enough for the event and I only have one battery so I assume I should pick up another. What do u think?
