A digital controller in a photographic camera comprises a microcomputer and one or more digital computer controlled input and output transducers such as scene light measuring means, subject distance measuring means, and means for controlling aperture size, shutter time, or focus adjustment. The microcomputer receives inputs from the input transducers and controls the output transducers in response thereto according to a control program stored in a computer memory. The controller includes a programable memory containing custom control constants to custom tailor the operating program for the specific apparatus in which it resides. According to a preferred embodiment of the invention, a high precision photographic camera is produced by first making the photographic camera, then operating the camera under known operating conditions using a nominal control program. The responces of the output transducers under the known operating conditions are measured and custom tailored control constants are generated for the camera. The custom tailored control constants are then programed into the programable memory to bring the operation of the camera into conformity with desired parameters to complete the manufacture of the camera.
