Charles O'Rear is the photographer who took Bliss, the image that became the desktop of every single Windows XP computer in the world. Billions saw it and probably think the photo is so perfect and colorful that it is computer generated—or at least Photoshopped. O'Rear reveals the origin of the photo in this video.
So there you have it. The secret to such perfection was just a perfect hill on the perfect time of the year with a perfect sky combined with some color Fuji Film inside the legendary Mamiya RZ67 camera sitting on top of a tripod. No retouching. No computer generated anything. Just one amazing photo with a punching color combination. He thinks that if he had made the photo with a 35mm SLR it wouldn't have been the same.
