A great place to find out how to shot certain photos is in the camera forums, like Nikon or Canon - I'm sure they'd even have specific advice on your particular camera or someone there willing to help .. BTW.. those sun protectors peoples use in the cars across the dashboard make great reflectors.. to dull down the shine, spray with hair spray.
I found this on DD's flickr page - a short piece on indoor flash with a link to more good info -
..
"Two major sources of info for me were the Planet Neil blog (http://www.planetneil.com/tangents/) and a series of articles at P.O.T.N., a Canon forum (http://photography-on-the.net/forum/...d.php?t=138907). Neil is a professional photographer who does beautiful work and uses flash, including on camera flash, a lot. He also has a Flickr group where you can ask questions; I think the link must be on his blog. Oh, and he shoots both Nikon and Canon, which is helpful. I cannot say how much of the info on the Canon forum is truly Canon specific--my guess would be that a lot will apply to Nikon and other brands as well--but you're on your own there!"
