i saw that on dootalk a while back, then sent it to my photgraphy savvy uncle, and he said it was not a photoshop; the snow coming from the track is too good, also, all the shadows are going in the right direction and are perfect....
that is the elite from the local ski-doo shop in my area. I sure would like to buy a demo from him!!! he don't care, and either would I if i were him.
