PURPOSE:To properly select the shortening of photographing time, valuing the vividness of colors and valuing the sharpness of a picture having no blurs, etc., by variable setting and separately controlling the luminance of a monitor, the stopping value of an diaphragm and the time of exposure according to the condition of photographing. CONSTITUTION:A filter rotary plate 3 having respective filters of R, G and B, driven rotatively by a motor 3A, a shutter 4, the diaphragm 5 and a lens 6 are fitted between a black-and white monitor 1 and a film 2. The respective signals of R, G and B are amplified with specified gains in amplifiers 9, 10 and 11, switched in a switch SW 12 and inputted in the black-and-white monitor 1. The gains of the amplifiers 9-11, the time of exposure of G, R and B in a switching timing device 7 and the stopping values of R, G and B in a diaphragm controller 8 are set in a CPU 13. The above-mentioned set values can be varied according to the kind of cameras and films by the CPU 13.
