A system including an imaging device, located a distance from a surface, configured to capture an image of a latent print or a contaminant on the surface at a first aspect ratio and with a first field of view on a surface, and a light emitting device, located a distance from the surface, configured to illuminate at a ultraviolet-c wavelength or a long wave infrared wavelength at the surface at a second aspect ratio equal to the first aspect ratio and with a shape of a field of view on the surface equal to the first field of view on the surface is disclosed. The captured image illustrates a reflected light image of the latent print or contaminant in a visible spectrum. A method and a non-transitory processor readable storage medium are also disclosed. |
