I agreed to be a second shooter for my brother-in-law at wedding he's shooting in a month. I know, it's pretty short notice. Keep in mind, we live in little Canadian hick towns, this isn't a big deal here Before you look at my gear list and pounce on me like a hungry lion for taking on a wedding, be aware that I am a second shooter. There's no pressure; I'm there for the experience and to catch some shots that he might be too busy to get. I'm putting together a list of things I should have. MUST HAVE: 3rd spare battery (already have two) ORDERED Diffuser for SB-600 ORDERED Two or three 4GB SD cards (I currently have three 1GB cards) WOULD LIKE TO HAVE: Lowepro Nova 190 AW or 200 AW shoulder bag Off-camera flash (Alienbees Cybersyncs) Anything else? I've also been looking to upgrade my main gear recently with a D90 and some fast zooms. While this gives me a good excuse, I don't have the money for it right now, so I'm not going to concern myself with it.
