Disclosed is a device for capturing digital images of a rock specimen in a region of interest. The device includes an inner chamber having a wall surrounding the region of interest, the chamber having a specimen support structure at the bottom of the region of interest and an open top opposite the specimen support structure, the specimen support structure dimensioned to receive and support an elongate core sample in an upright orientation within the region of interest; an imaging system associated with the chamber and comprising multiple digital imaging devices spaced around the region of interest, each digital imaging device oriented to have a respective field of view encompassing the region of interest; an illumination system associated with the chamber and switchable between a first illumination state and a second illumination state and comprising a plurality of illumination sources spaced around the region of interest, the illumination sources operable to direct intersecting illumination patterns into the region of interest; and a control system coordinating the imaging system and the illumination system to capture a first set of digital images during the first illumination state and a second set of images during the second illumination state. Systems, methods and computer-readable media are also disclosed.
