Originally posted by alinla The problem with reducing the ambient with an ND filter is you are also reducing the power of the SB28. So in bright daylight (roughly 1/125 @ f16) that SB28 is gonna have a hard time lighting the subject effectively in any situation other than very close proximity. And don't even think of using a light modifier because it'll suck all your light away.
Good point. I've been thinking about this and completely overlooked that in my first thoughts. But, when you read the info by David on Strobist, he shoots at 1/4 to half power in many of the shots when he's overpowering the sun. Even with a ND filter and the flash on 3/4 to full power, you have the same relative light ratios, right? It just lets you do it with the slower sync speed.
Also, I'd like to hear how you get a faster off camera sync speed. I can only get 1/160th.
