Modern cameras are amazing instruments. They've taken a lot of the guess work out of image making and produce a decent image without too much mucking around afterward. I have found that every photo benefits from some adjustments after the fact. Most of my old images were taken in JPEG only format so I'm limited as to what I can do with them. In this case I darkened the sky a bit and also the snow in the lower right. A simple levels adjustment to heighten the contrast and voila!
