If you don’t like the look of harsh lighting caused by your external camera flash, you may want
to check out these two items. I bought the Gary Fong lightsphere a couple of years ago, and find it really works. I see wedding photographers use this thing, and it looks like a Tupperware bowl stuck on the end of your flash, but it’s quite handy and and does a good job of diffusing the harsh light from a flash unit. The Rogue Flashbender is very different from the lightsphere, and can double as a snoot for directing light to a smaller area, without much light-spill.
