swankenstein:I don't know much about digital cameras and from what I've been hearing, I have to ask: Why is a digital shutter so different from a film shutter? With film, you have to sync the shutter speed with the strobe, but in digital you don't have to? And is the flash duration so long with a digital strobe that you can use a higher shutter speed to cut out some of the flash? By the way, for a diffuser, I've used white plastic grocery bags held on with a rubber band. They do make the light a bit warmer, but I've realised it's hard to find a "homemade" diffuser that doesn't shift the colour abit. It's usually too small of a difference to notice though.
Either do a white balance adjustment or correct in photo shop - with photo shop being easier.
