Tawabaware has posted information about a recently assembled high resolution photo of Bryce Canyon that is over 1 gigapixel in size. The image measures 40,484 x 26,800 pixels and contains about 1.09 billion pixels. The web page and associated links explain how the photo was assembled along with several comparisons of resolution. It speaks volumes. Especially when compared to a Powerpoint image!

This is a very interesting, detailed, and involving (mosaic) panorama. But compare David Hockney's quarter century photo and painted works of the Grand Canyon, e.g. (http://davidhockney.online.fr/Grandcanyonwithledge.htm) and an 88 panel photomosaic, and progressing to his his 60 panel "A Bigger Grand Canyon" (http://www.discoveryfund.org/images/PHOCKNEYCANYON.jpg) and the larger, 96 panel, "A Closer Grand Canyon" These wonderfully represent and suggest the scale and depth of the Grand Canyon. More, through the differing perspectives of the component photos, they force the viewer to constructive meta-experiences evocative of visiting the Canyon itself. I think these "Grand Canyon"(s) are masterpieces and quantum advancements in the techniques of landscape art and imagery. Hockney shows more than what is seen in big, detailed, giga-pixel images. J>D> P.s. A question: in describing or defining "resolution" how are image components [e.g. pigment size, film grain, pixels, wave length, etc.] together with the original subject size, image area, and viewing distance related to determine "sharpness" and/or "detail" --beyond the obvious the more compnent "dots" per area the sharper the image -- and do the "layers" or "richness" of information per storage unit/area also affect resolution [as they do understanding]?

David Hockney's "joiners" have long been interesting and worth thinking about; they break out of the one-eyed flatland of single photographs. One of the best is Pearblossom Highway, 1986 at

Justice Thomas doesn't seem too interested in the event, zooming in on his features! On some zooms, there seems to be a misalignment of features - does this technology "paste" a number of different shots together?

400,000 pixels wide by 12,500 pixels tall is this image of the Vietnam War Memorial. Here is an example of one of the names on the wall. http://www.footnote.com/image/48295936/lewis|lewi|albanese/ The viewer allows you to zoom in and out of the wall or search for a name.
