This weekend, I will be attending a reptile expo in Daytona. I have decided on taking my camera with my 18-55mm. This place will be extremely crowded, so no tripod and flash is frowned upon. There will be several species of animals there that I don't get to see everyday and I want to be able to take some decent photos. The lighting will be ok, mostly large halogen bulbs. Does anyone have any tips? This is supposedly the last year it will be in Daytona, so I don't want to miss any shots.
