This is a stitched-together image of Bryce Point in Bryce Canyon National Park in Utah. It consists of 196 separate photographs taken with a 6 megapixel digital camera, and then stitched together into one seamless composite.
The final image is 40,784 x 26,800 pixels in size, and contains about 1.09 billion pixels...a little more than one gigapixel.
This image is roughly 100 times sharper then human eyes with 20/20 vision see naturally. If it were printed out, it would be 11 feet wide, or 12 pieces of paper printed landscape with no margins.
Here is a strip of the image. It is only an inch tall, but look at how wide it is!
Here is the site I saw it on...
