I don’t know about you but I never get tired of these dramatic cloud shots. Technically they aren’t all that complicated. Take a picture on just about any day where there’s a decent amount of clouds. They don’t have to be very dramatic at all. The original of this shot is nothing like what I ended up with (which some might disagree with also.) Take it into photoshop and goto image/adjustments/auto level. I normally don’t care for auto leveling shots, but here it works to bring about those dramatic colors. Then hit ctrl-j (not sure of the command for you Mac users just duplicate the main layer) change the top layer’s blending mode to overlay and back it off with the opacity of the layer as needed. I took mine into Neat Image to remove some noise and smooth it out some. There you have it…crazy apocolyptic like clouds in the sky.
