Dog looks well exposed to me!

AV, this is an interesting comment - I've always found that high ISO shots need a considerably higher adjustment of contrast to get to the acceptable ballpark, and they usually look washed-out with little dynamic range out of camera. What is it that makes you feel higher ISO shots are MORE contrasty?
