Fun up at Penshaw this morning with Dave Brightwell (oh my bad for not cloning out the tripod shadow)
I really like these alternate 'hue' pics; they're quite infrared-ish. They're very easy to do:
Open your shot up in Adobe.
Add an adjustment layer of curves.
In the curves drop down selection, change to negative.
Open up the curves layer in Photoshop and change the blending mode to 'hue'.
