Abstract

PURPOSE: To reflect easily and properly photographer's intention on an exposure photographic condition determined by a program by shifting the shifting manually the photographic conditions determined by the program.
CONSTITUTION: The output-side switch Sw of a comparing circuit 16 is closed at the initial stage of depression of a shutter release button to start setting circuits 8 and 6 for arguments α and β, and an aperture value Av and an exposure time value Tv which are calculated are stored in storage circuits 17 and 18. Switches S1 and S2 are operated to vary exposure factors determined by the program. With the switches S1 and S2, an up/down counter 22 counts up and down and the contents of the counter are set to a subtracting circuit 24 and an adding circuit 25 and added to the Av and Tv stored in the storage circuits 17 and 18 to change combinations. The final values Tv and Av are displayed on a display device 20 and sent to an aperture controller 19 and a two-curtain controller 21.
