| Dr. Kenneth B. Castleton's excellent directions to many
Utah rock art locations were of inestimable value. Special thanks are
due Dr. Richard W. Effland, Jr., Anthropologist in the Cultural Science
Department, for his advice and encouragement and for posting these pages
on the Mesa Community College server. Ken Costello and Robert R. Farwell
provided assistance in the Media Center. The technicians in the Library
and Computer Laboratory have always provided excellent help and are to
be commended for their patience with us students.
The rock art sites were photographed by the author using Kodachrome 64 slide film. Fieldwork was accomplished from 1983 to 1994. Transparencies were scanned at 675 dpi with a Polaroid SprintScan 35 slide scanner using Adobe Photoshop. The acquired images were first adjusted for levels, sharpness, contrast, brightness, color balance and color saturation. This process was conducted with the intent of increasing the visibility of the glyphs and correcting for exposure. On average sharpness, contrast and saturation were increased and color was shifted only slightly, typically to increase red and yellow. The files were only manipulated as a whole and most are otherwise unaltered. These were saved as high quality JPEG files. For these pages, the 675 dpi files were converted to 72 dpi files and reduced in size using Adobe Photoshop. (After word 2005: The 1997 technology has been replaced by a 4000 dpi Nikon scanner on my desktop, now an affordable tool for individual users. I can reacquire the images at higher quality for publications.)
For the artwork, slides were projected onto 30" by 22" Rives watercolor paper and rendered with India ink to produce black and white drawings. Careful attention was taken to produce photorealistic images. These were commercially photo reduced to 8.5" by 11" paper, then the images were electronically acquired by a Hewlett Packard ScanJet 4C using Adobe Photoshop. The background images based on the artwork were colorized using Adobe Photoshop, most in duotone mode then changed to RGB mode to save as 72 dpi JPEG files. Some were exported as GIF files.
On the Mesa Community College campus, all the scanning, computer work and page creation was accomplished using Power Macintosh computers (7600/132, 9600/233 and 6500/250) at Media Services, the Computer Laboratory and the Library Information Commons. The pages were created using Netscape Navigator Gold 3.0. In my own office I used a Mac IIfx, Adobe PageMill 2.0, Adobe Photoshop LE, Adobe SiteMill 2.0 and I edited HTML files as text documents with Microsoft Works 3.0 or BBEdit Lite.
The original pages were created in 1997 and posted on the MCC server. I currently maintain the site with Dreamweaver. The entire site was edited and moved in July of 2000 to Geocities. In Nov. 2001 I moved the site to my new domain, jqjacobs.net, on a HostSave server. The Fremont Rock Art page was added in 2005 with images scanned on my new Nikon CoolScan.
