Thanks Doobsy! Well what I did was set the camera manually to expose the sand close to the 5th stop or close to the right. Then, I set the flash to 0 EV on high speed ettl. If you want to catch rapid shots in succession, then a flash battery pack will help. Anyway what this did was allow me to take high speed photos with alot of shadow detail. The photos actually look very flat out of the camera, because in theory I only captured only 2 or 3 stops of light. I then simply dragged down the black point of the photo to give better contrast. After you drag the black point down, the skin tones are kind of go too wonky dark because of the technicalities of camera limitations. But because the technique produces alot of digital information, you are able to make a bump in the curve to make a natural appearance. The same kind of considerations work well in snow too, where the background reflects alot of light. It's just a trick I learned to use when normal exposure methods don't work
