Some camera mfgs say to balance to white, some say gray.
Does it matter?
Why or why not?
It probably depends on the camera. It's important that no channel
be clipped in the image it build the white balance from, and that's
probably easier to do on a white card than a gray. Depending on the
workflow for custom whitebalance in that camera.

I am curious why so much emphases is placed on in camera white point
correction. It just seems so trivial to adjust the white point that I
set my camera to auto and don't worry about it. I use Picturewindow
Pro as my image editor of choice. It takes two or three seconds to
correct any hue or color cast problems. If something in the image
isn't white just make it so and every thing else falls in place. For
PS users there is a plug in available for PC an Mac at:

Here i the URL for an example I used in another discussion:
http://www.pbase.com/dave6134/image/72302629/original
The warm image was with ambient light from a sixty watt bulb (about
3000K) behind an off white shade. The cool image is an attempt to
approximate light from noon daylight from a north window (about
6000K). The white point could have been moved to any degree Kelvin
between the two or beyond.
Am I missing something here with this white correction thing?
