This image is the latest in a new series of experiments in which a series of side-by-side shots are blended together to create a sharper, richer one. In this case, a camera with a 70-210mm lens was placed on a tripod in vertical, or portrait, mode. Three shots were taken, each slightly to the right or left of the others. In a computer, software was used to overlay the three overlapping shots to line up the tall saguaro cactus near the center. The extra image area on either side was trimmed away. The goal is to create an image so detailed that a much larger print may be produced without loss of definition. Here, the blended image was nearly 200 megabits in size; the trimmed version (which was brightened and subjected to other typical edits) was approximately 155 MB in size. What you see here was reduced from a JPEG copy that is about 9 MB in size.
In the distance are the Santa Rita Mountains. The camera was placed in the Tucson Mountain Park west of the city of Tucson, Arizona.
