That is a beautiful camera he's using that on. ;)

I try to avoid using flash as much as humanly possible, I prefer the noise of 1600-2000 over the pseudo-colors created by flash. In the events that I do use the flash, I've been more or less satisfied by the diffusion filter that came with it. I'll have to try the paper filter though, interesting results. Now quite as pretty as the gary fong though. Thanks for the link.
