Think of a camera's sensor as a very special kind of film. If you shoot in shade, bright sunlight, mountain top with snow, etc., your film shows the scene differently than you see it. So, just as you used a gray card with film, you can use a white balancing card (an accurate gray card really) with your sensor. >From all that I have read and experienced (both with 35mm sensor and MF digital back), it is much better to shoot a gray card of the scene and change the white balancing in the camera rather than adjusting post shoot. This works best, of course, if your shooting a series of images in the same light situation. The reason I think this is true is I just shot a scene recently using a 10-stop ND filter. Without adjusting for white balance in the camera, the file (raw) came out extremely blue. Shooting a WhiBal card and adjusting the camera to that gray at the time of shooting gave "perfect" colors. Trying to adjust in LR to the WhiBal card gave color quality somewhere in between. IMO of course?
