I'd love to say that this was taken in the canyons in Arizona, but it isn't (I wish!). I created it my bedroom - the background is an orange voile curtain, scrunched up. The 'tree' was found outside, which someone had conveniently stepped on to flatten it (I think it's from a shrub of some kind, possibly elder) and the light shaft was created curtesy of the DigitalPhoto technique (although I did try to make it subtle!).
Exposure for the background was 1.5" @ f8 - the tree was masked out from another similar image and inserted (and boy, was it a sod to mask!) Then turned the image black and white by using the red channel only. I like it, but I'd welcome feedback from others - does it work?
