So, the camera turns down the exposure because it thinks the image is over-exposed. However, this leaves the snow looking the colour of concrete. So, turn the EV value up a stop, and it will increase the exposure, making the picture brighter and the snow look white - exactly the way it's meant to.

Would this still happen if I did a custom white balance using the snow as my WHITE and an EV0? Many cameras has a scene mode for SNOW, I assume that one of the things it does it is exactly what you just described, correct?
