While experimenting with RAW exposure I tried for a dramatic effect in this cloud shot. I probably overdid it, but I wanted to see how far I could go before it started to look artificial. In Photoshop I did Contrast [+], Unsharp Mask, and a bit of Crop along the left edge. The natural curvature along the bottom makes it look kinda fish-eye, but that's just the way the clouds & trees were arranged. My favorite part is the little "Maxfield Parrish" cloud banks along the bottom.
