Rio de Janeiro - Carnival photography
I shot the carnival a few years ago and was very pleased with the experience. If you get a seat in the stadium, you'll be doing snapshots more than anything else. I managed to get into the area where the performers prepare their costumes and floats and captured some terrific photos. I was careful not to bring a full kit of gear but my camera and a good flash (and small bag to carry it). While it limits the type of photo you can take, it makes it much easier to get around and focus on the shots you can take.
