ABSTRACT:
A motion picture camera wherein the trigger of the camera release is movable from an extended position to a second position in which it starts the camera motor, and beyond the second position to thereby cause an auxiliary tooth to enter a gap in the annulus of teeth at the periphery of a program wheel which forms part of the mechanism for making exposures with dissolve. The auxiliary tooth is thereby moved into the path of cyclical movement of the pallet on a pawl which is driven whenever the motor is on whereby the pallet can move the program wheel from a starting position and thereupon cooperates with the teeth of the program wheel to rotate the latter through one revolution during which the program wheel initiates the making of exposures with fade-out and subsequent rearward transport of film frames which were exposed with fade-out, and prepares the motor for renewed forward transport of such film frames with simultaneous exposure with fade-in. The renewed forward transport is effected by depressing the trigger. The motor remains in operation while the user moves the trigger beyond the second position so that the making of exposures with fade-out can follow, without any interruption, the making of normal exposures.
