Panasonic GH2 + their 7-14mm lens. No filters. Shot in color and converted to B&W using the SilverEfex plug-in in Photoshop. Can't remember if I used a red filter in the conversion, probably not. I just tweeked the the contrast.

 Love the photo! Any filters used? (Neutral density, red/blue for the sky since its B&W?) Just curious, since I love how it turned out in monochrome!
