The reflective meter is tricked by the overabundance of white, when it's trying to match to an 18% grey. If you don't have exposure compensation, you can go into manual mode and bump the exposure that way. Hope that helps. =) Hehe, this answer is a bit late, however, if you use the exposure compensation on your camera, you can bump the exposure +1 stops and that should fix your underexposure problem.

One or two stops might not be enough, or I might have to actually stop down a few notches. For example, Newfoundland is filled with the reflections of light on water, the glare of snowy days, dreary and mournful fog, and various white critters. If there's no adequate reference item in the environs for the TTL reflective meter to hit, then it complicates matters somewhat. At the very least, I have to get a grey card, but much more preferable (though also much more expensive) would be a decent incident light meter.
