The recent advent of low magnification microwear analysis has allowed the efficient study of entire vertebrate faunas using only an optical stereomicroscope. Photographic visualization of microwear by this means has proven difficult, however, and, as a result, few high-resolution photos of low magnification microwear have been published. The repeatability of the method has also been questioned because low magnification microwear analysis involves the visual inspection of microwear features. We show that the use of high dynamic range imaging improves the visualization of microwear features in photographs and that using these photographs as a counting medium increases the repeatability of the method. We also show that counting from the photographs allows us to accurately classify ungulates as browsers, grazers, or mixed feeders.
