Abstract
In a camera adapted to function with stored data, the exposure time data, aperture value data and override data are stored and the stored aperture value data is normally indicated with provision for indication of the stored override data in place of the aperture value data. The stored exposure time data may be indicated by additional indicating means which can be disabled while the stored override data is being indicated.
