>>3238836I'm not a trained arborist, but my bachelor's was in biology with a botany emphasis (granted, not that that means much, but it means more than nothing), and given that Peter Lik lives in Las Vegas, Nevada, America (according to Wikipedia), and given my experience with trees with white bark that grow in uniform stands in North America (there is literally only one species here that looks like this), I'm 99.9999% certain that
>>3237299 is a photo of quaking aspens that has had a uniform yellow to red shift applied in postprocessing, if not had all or some of the leaves added/painted into the photo, as originally suggested by the other anon. My 0.0001% of uncertainty comes from the fact that I don't know all species of trees in the world and it's possible that such a tree exists in Europe or Asia, although that would be a long way to travel when the same result could be achieved with a 2 hour drive from his home and a bit of Photoshop work tot weak the colors.
Since the image you posted is "blodbjork.jpg," I'm assuming that you don't live in North America, so although I'm explaining all my assumptions and reasoning as if from scratch, it's obvious to anyone who has lived in America, since there's only the one type of tree it could be, and they are so uniformly yellow-leaved in the fall, it's obvious how the photo has been processed.
