Using a gray card is a good idea. But honestly, chimping works decently too. Throw a 1/4 CTO on your flash, take a shot, then look at the results on the LCD (it's better to use a laptop, but the LCD will work in a pinch). If the light hitting your subject is noticeably cooler than the ambient, then try a 1/2 CTO, and so on. Soon enough you'll be able to guess what you need (and be right most of the time).


Peety's way is certainly more technically accurate and will work fine. If I had the patience, I'd probably do it that way too. :-)
