ABSTRACT:
A fade photographing controlling apparatus for a cine or movie camera comprises a rotary member adapted for alternate rotation through 180.degree. in a first direction and in an opposite, second direction, and a cam member including first and second eccentric cam surfaces and adapted to be coupled with the rotary member for rotation therewith only when the rotary member rotates in the first direction. The initial rotation of the rotary member in the first direction is utilized for fade out photographing, and the succeeding rotation of the rotary member in the second direction is used to reversely feed the film portion which has been used during the fade out photographing, while a final rotation of the rotary member in the first direction is utilized for fade in photography on the same film portion. The cam member controls the opening and closing of a shutter during the fade out/fade in photographing, and means are also provided to control forward and reverse feed of the film whenever fade photographing is performed. Clutch means is provided to transmit or interrupt the rotation from a motor to the rotary member, and is controlled by an operating member which may be operated externally of the apparatus.
