Photography and Scanning

Department of Geological Sciences (High-Resolution X-ray Computed Tomography (CT) Facility), University of Texas, Austin: Image Folio. High-resolution X-ray CT (Computed Tomography) is a completely nondestructive technique for visualizing features in the interior of opaque solid objects, and for obtaining digital information on their 3-D geometries and properties. What is X-ray CT? Eexcerpted and adapted from: Denison, C., Carlson, W.D., and Ketcham, R.A. 1997. Three-dimensional quantitative textural analysis of metamorphic rocks using high-resolution computed X-ray tomography: Part I. Methods and techniques. Journal of Metamorphic Geology, 15:29-44

Stefan Bengtson, (Department of Palaeozoology, Swedish Museum of Natural History, Stockholm); In: Palaeontologia Electronica, Volume 3, Issue 1; 2000 (Coquina Press): Teasing Fossils out of Shales with Cameras and Computers. Simple yet effective methods are available (using Adobe Photoshop) to enhance photographic images of low-contrast and low-relief specimens, such as fossils in shales, without manipulating or retouching the photographs. By applying polarizing filters to camera and light-source(s) in a way analogous to crossing nicols in a petrographic microscope, dramatic results can be achieved where there is a difference in reflectance between fossil and matrix, as with many coalified fossils. Excellent!
