About the Photo

Mesa Verde National Park is on a high plateau in southwestern Colorado (near "4 corners"--where Utah, Colorado, New Mexico and Arizona all meet).

The building is a Native American (Anasazi) cliff dwelling built into a natural cave midway down a cliff about 100 feet high (as I recall). I took the original 35mm photo in September 1993.

I scanned the negative with a Nikon "cool scan" at 100 lines/mm into Adobe PhotoShop where I stripped the color and adjusted the contrast. I saved the image as a "portable graymap" (PGM) file and wrote a Unix shell script to tile it into N by M panels and convert them to PostScript. I printed the panels on a NeXT laser printer and glued them together into a poster-size print. Most of the image format conversion, tiling and resizing was done using Jef Poskanzer's Portable Bitmap tools on Unix.

The miniature in my webpage is a 10x linear reduction (100x area reduction) of the original. The original is 5.6 megabytes as a GIF and 17 megabytes as PostScript. As you might guess, with that much detail, the poster-size version looks pretty good.
