A photographic exposure apparatus and method for preparing production artwork of an image to be reproduced by photo-engraving. Prior art handwork or manually operated devices employed in modifying artwork images required high levels of skill and considerable time to achieve satisfactory results. The subject apparatus includes a movable panel superposed on a stationary plate for supporting a film containing an image to be reproduced in contiguous contact with a light sensitive sheet superposed on the stationary plate. An eccentric motion dial guide connected with a drive motor and connected with the film support panel is manually adjusted and the motor energized for orbital movement of the film support panel in a path of predetermined magnitude during exposure of the image on the light sensitive sheet.
