So like the title says, I'll be shooting this event for Transowlorld MX. I'm totally stoked. It's at the Santa Monica Pier and it starts around 7 and Ronnie Renner will start jumping at 8ish. Now, Here's my question. I'll get all the PJ type shots early and I'm not too worried about that. I'm bringing my tripod to get some long exposure shots and whatever else. I'm wanting to shoot a sequence shot like this: So, this is where I get confused. Will I be able to luck out, and have enough ambient light to pull off a semi fast shutter speed to do the sequence? or will I have to bust out my 580EXII ? If I'll have to use my flash, is there a way I can have it continuously fire for 12-15 shots? I'll be using this setup: 1DIIN 70-200 2.8L IS 17-40L 580EXII Any help would be great. Thanks.
