Infrared sky

I was passing near the Empire State Building yesterday when a dramatic cloud formation passed behind it, and I grabbed this shot with the handy Sony RX100 that is always with me.

The sky was a crisp, deep blue so when I returned I processed the image using an infrared filter from Alien Skin's Exposure software. In case you are not familiar with it, Exposure provides a set of filters that mimic film types. These could be standard black & white films, color films, vintage films, cinematic films, antique photographic processes, and much more. The effects are fully editable offering a huge range of options and the ability to tweak each filter to your own style.
