I have never had a digital camera where changing the white balance DID'NT
make an enormous difference in the output! Whether it made the intended
difference is another story, lots of experimentation required. Your digital
strobe MAY make a difference, but with any other flash or strobe above
water, white balance changes have a very visible impact.

The laws of light do not, but your results most certainly do, if you are
using a light-gathering lens, or even just a red filter. BTDT

Not at all. You just have to buy the digital SLR from the company that makes
Velvia, instead of dicking around with a digital camera from a company that
has never made film ;-)
