From my understanding, changing WB does nothing in hardware, rather it shifts colors based on what you tell the camera/software what WB to use. For example, with tungsten light, it will shift down the red, and shift up the blue to balance neutrals. The math is over my head, but there is a

I'm certainly no expert on the subject, but it seems to me that putting filters in front of the lens of a camera with a digital sensor in it is a bit silly especially for BW purposes. Your sensor is already filtering the light through three filters to achieve a red channel, a blue channel, and a

If you have infinite precision and/or infinite range on your sensor, you would be right. But if you're trying to get a usable amount of information from each of the channels you want to have reasonably similar range on each one; you don't want one channel squashed down into just four bits of
