I am having a hard time firguring out should I get a diffuser or bounce card for my shoe mounted SB-600 flash. I made A Better Bounce Card from abetterbouncecard.com and I am not getting great results. Well actually I like the results when I move the bounce card to the front of the flash then it diffuses the light really well but I feel that I am wasting a lot of my light going out the back. So I'm looking for some recommendations, I don't want to really spend more than 30, under 20 dollars would be better. I want to use it for portrait work inside and outside fill flash. Actually that brings me to another question, I read something once that said don't put any thing on your flash when using it for fill flash, but wouldn't you still want to diffuse the light? I know I see a lot of wedding photographers using the omni bounce, but I'm really wondering how well that works? Thanks.
