I'm getting an opportunity to shoot at an upcoming motorcycle show in Seattle. I will be there before the show starts so I have plenty of time for each shot and no one will be getting in my way. Does anyone have any tips for getting great shots? I'm especially curious which filter(s) you'd recommend, polarized? The flashes I use will be limited most likely to the built in filter on my D50 but I can purchase any filters I need. I have two nikon lenses, a 28-80 and a 70-300 to work with. Thanks!
