Hello, My friend is DJing at a club this weekend, and I've been asked to take pictures of the event. Unfortunately, the venue is going to be very, very dark, lit mainly by candles. I hope to get some good pictures of the attendees, but I'm torn about what setup to use to get the best results. Essentially I'll be right up next to the DJ and the attendees, so my stock Canon FD 50mm/1.8 lens should do well. However, checking lighting conditions with some sample metering around my room, it seems to be near impossible to get anything near the 1/125 or faster shutter speed I'll need for dancing people. Flash is prohibited, so the best I can think of now is Fuji Natura 1600, and I feel like if I don't push it to 3200, I wouldn't be able to get a fast enough shutter speed. This is going to get really grainy, isn't it? Also, I've heard that using a lens at its widest aperature will often provide a degradation in quality, so should I favor pushing the film and shooting at smaller aperature? If anyone has experience in similar conditions and could offer some advice/sample configurations, I'd be much obliged. Thank you!
