Hi....I'm sorry it's been a while since I've been here or contributed too much, but I am in dire need of some opinions. I think my last post spoke to me shooting a horse show on Sept 12 in an arena in incredibly bad lighting. I spoke to my camera store briefly today and the SB900 was recommended to me. After that I was looking at Quantum packages as well as Norman 200 Watt system - which to me look like they can be pricey & complicated. But neither here nor there...I have two Speedlights already one SB600 and an SB800 but was told by one professional in the horse photography business not to shoot them (she didn't tell me why, this was over email) but when I talked to my photo shop I told the guy there exactly what I was going to be shooting and he recommended the SB900. I don't mind spending the money for the 900 but I'm really reluctant to step up to one of the professional set ups because I simply don't like shooting with a flash...not to mention I don't know how to effectively use it. Any suggestions regarding the SB900 - keeping in mind I will be in the center of the ring which measures approximately 200' x 80' and I will be shooting the horses as they come by me which will be anywhere from 20 - 45 feet away from me. The lighting is florescent with some natural light coming in from the top windows. It's just bad all the way around. Will the SB900 be enough? Anyone? Thank you...I'm getting to be a trainwreck that I am going to take lousy photos from light perspective - the horse part seems easy to me...the light is going to make or break me. Thank you for taking the time to read my plea...lol.
