Abstract Digital photography is an important tool to depict geologic features at all scales. Roxborough State Park offers an excellent laboratory to practice the skills and art of geo-photography. Three regionally significant Paleozoic through Early Cretaceous sedimentary formations (Fountain Formation, Lyons Formation, and Dakota Sandstone) offer important textural details, outcrop patterns, and structural relationships that provide photographic challenges and opportunities. In photographing these features, basic principles of composition apply, including the rule of thirds and the use of leading lines, foreground, and depth of field. To engage these, geo-photographers need to use important in-camera tools that include aperture, shutter speed and appropriate ISO (an adopted standard from the International Standardization Organization), as well as a tripod, and suitable lens focal length. Choice of file format (RAW or jpg) has important consequences for final image quality. Post-processing is essential to ensure that images accurately depict the features intended, and may include adjustment of levels, color temperature, and sharpening. GigaPan images offer an additional tool for examining geologic features at multiple scales using up to several hundred stitched images. Photographs are an important venue for communicating geologic information to both professionals and the general public, and the more the compelling the images, the more effective the communication will be.
