The invention provides an apparatus and method for imaging markings on cartridge cases. It provides for the taking of two images of the cartridge case with light for illumination projected at the cartridge case from two different predetermined angles. In a first version, two different light sources are set at the two different predetermined angles. In a second version, one light source is moved between two different positions to project light at the two different predetermined angles. In a third version, the device holding the cartridge case is rotated between two different positions so light projects at the cartridge case from the two different predetermined angles. In a fourth version, the holding device rotates the cartridge case between two different positions so that light projects at the cartridge case at the two different predetermined angles. In another aspect, the invention provides diffuse light for the taking of the images. In yet another aspect, the invention provides a cartridge case holding device which can rotate the cartridge case about a longitudinal axis.
