Hey guys. I was looking at several professional portraits, and I couldn't help but realizing the awesome lighting job they do. I know they have some umbrellas tilted probably at 45 degrees on the four corners of the object, but can someone either teach me some cool techniques other than that, or link me to a place that can (in case you don't want to type that much). Also regarding bounce diffusers like sto-fen, what're they good for? Is it primarily to reduce the lighting exposed on the subject so it doesn't "ruin the mood"?. Do bounce diffusers serve more of a purpose than that? Thanks! Also, I want to get into some cool lighting tricks, but I don't have any professional setups. Is there any other alternative I can do with just a 430ex?
