Shot in Huddersfield, UK as 3 separate exposures (+2, 0, -2), then combined in Photomatix to a HDR file.
I then created 3 layers from the HDR file and made separate B&W layers of them (blue + 2 reds through the channel mixer), then altered and blended each layer separately for different parts of the image. Afterwards I toned it slightly to blue with curves.
