Over thirty years experience recording rock art worldwide on 35-mm slide film and digitally.  Concern with image-degradation in private research materials led to developments of image enhancement techniques in 1999 using Photoshop that became standards in the field. Concern for site conservation led to multimedia services that combine precision GPS, GIS, high resolution digital images, 360-degree panoramas, Gigapans, DStretch, 3-D imaging, pXRF, UAV aerial photography, and CD/DVD technology.



Archive activities include scanning research slides, drawings, and photograph collections of individual rock art researchers, creating image databases, and archiving images and data to CDROM, DVDs, or larger capacity hard drives as appropriate.
