Hope this is the most appropriate forum for this question. I've got next-to-no experience of flash photography but I've been given an SB900 so I might as well give it a whirl and have some fun. I've been hanging on to see if Thom Hogan's Nikon Flash Guide would be updated but no sign and I know he doesn't set timescales. So my question is, if it's not the Hogan resource, what is my best learning resource for developing my understanding of flash and specifically the SB900?
Thanks
