A photographic exposure control system of the type for controlling both the duration of a photographic exposure interval and the amount of artificial illumination provided during the exposure interval includes the capability of increasing the amount of artificial illumination in direct corresponding relation with increases in the camera-to-subject distance and the ambient scene light intensity in order to maintain the same proportional contribution to the film exposure from the ambient artificial light during a fill flash exposure.

A photoresponsive, shutter-diaphragm exposure control system having light regulating blades displaced from a light-blocking position to define increasing aperture values during an exposure interval includes a source of flash illumination which is energized with or just prior to initiation of the exposure interval for flash operation. In this arrangement, the flash illumination envelope is superimposed in a leading arrangement on the aperture opening curve so as to provide increasing illumination intensity in slightly leading relation to the increasing aperture values.

There are disclosed method of and apparatus for evaluating radiation in the scene. The evaluating apparatus includes a photoresponsive arrangement having a given angular directional response and a plurality of lenses respectively mounted for movement between a first position in optically operative alignment with the photosensitive arrangement for altering the given angular directional response thereof, and a second position out of the operative alignment.

A dual mode range responsive exposure and flash fire control system operates as a function of the photographic subject being located in either a near distance or a far distance range from the camera. For photographic subjects located within a near camera-to-subject distance range, a flash fire signal is normally provided during the exposure interval at the instant when the blade mechanism defines an aperture size generally corresponding to the camera-to-subject distance to ignite the flash and provide a determinate amount of illumination. For photographic subjects located within a far camera-to-subject distance range, a flash fire signal is normally provided subsequent to the shutter blades reaching a maximum aperture defining position with the flash output being subsequently quenched as a function of scene light detection and integration.

A photographic camera exposure and flash fire control system provides for a proportional fill flash by firing an electronic flash or strobe at an aperture appropriate for the camera-to-subject range. The flash is fired during the closing movement of the shutter blade mechanism and subsequent to the integration of ambient scene light to a select proportion of the optimum film exposure value whereby the remaining proportion of the optimum film exposure value is provided by the artificial illumination from the flash during the closing of the shutter blades.

A photographic exposure and flash fire control system initially measures ambient scene light and subsequently utilizes the results of that measurement to control the amount of artificial illumination provided during the exposure interval. The initial measurement of ambient scene light below a first select level provides for a maximum flash output while conversely the initial measurement of ambient scene light above a second select level greater than the first select level provides for minimum flash output. The initial measurement of ambient scene light between the aforementioned first and second levels provides for a flash output which progressively varies between the aforementioned minimum and maximum outputs in inverse corresponding relation with respect to the progressive variation of measured ambient scene light between its first and second select levels.
