Canon Rebel XS. Upgrading next February to the 7D. I have to have absolutely horribly overcast conditions to get decent waterfall shots. Have to get a set of filters soon. All I have is UV filters on both my lenses for protection mostly. Some of the waterfall shots come out okay anyway, but I almost always have to play around with them in lightroom to cut the exposure. Check out my gallery, there's a few in there.
