I will be purchasing a flash diffuser for a canon 430ex speedlight asap. I was just wondering which one works the best? I am really going for a non flash look. I guess that's what these are for, right?! I've been looking at the one's on ebay and there are a few different designs...some are like a mini light box you put over your flash...some are small white and plastic...looks like it just slips over the flash and there is also one that you blow up(yeah, with air!) I've never seen that kind. but then again this is the first time I have searched for one of these. So any info would be great. Thanks!
