Abstract
A lens-fitted photo film unit provides a daylight photography mode to select no flash emission and the small stop, a daylight synchro photography mode to select normal flash emission and the small stop, and a night view synchro photography mode to select reduced flash emission and the large stop. The small stop is composed of the small stop aperture of f/16 and an ND filter of transmittance of 25% to be attached to cover the small stop aperture. The shutter speed is set at 1/64 sec. in any modes. The photo film preloaded in the lens-fitted photo film unit has ISO sensitivity. The stable photographing is achieved under the wide range of brightness by the changeover of the stop, without the change of the shutter speed. In brightness of EVto, the exposure amount becomes proper either in the daylight photography mode and in the night view synchro photography mode.
