I like this, I've often tried to capture a really dark foreboding sky but never seem to be able to show just how dark it was. This shot looks like it does.
We were Popup camping in Western Colorado...this fellow in the next site was "Hammock camping"...which I understand is all the rage on the East Coast, this year.
I believe the droplets of water were added via Infranview, which has a few editing features, built in.
This image was never loaded into Photoshop :-)
