ABSTRACT:
A photograph assistance device for assisting a stationary camera in photographing a curved surface of cylindrical objects, such as a finger print wrapped around a bullet casing or soda can. The cylindrical object is moved at a constant speed into a photograph area of the camera while rotated at a constant rotating speed. The moving speed of the object is preferably determined so that the object can successfully pass through the photograph area of the camera while the camera and stop is adjusted for a small diameter opening for the best depth of field. The rotating speed of the object is preferably determined so that the image of the object can be rotated onto the field without producing a distorted image, that is, a stretched or compressed image.
