This is the second of the two shots I mentioned yesterday, the one I prefer. What I didn't mention yesterday is that neither of these shots are masked; i.e. I used a single Curve to adjust the contrast across the image as a whole. Normally, to achieve a sky as dramatic as either of these, I would use separate Curves – one for the foreground and one for the sky. On this occasion though the foreground was very well lit and the sky – heavy with rain – was comparatively dark.

As always, I'd be interested to hear what you think.
