Abstract

A lens-fitted photo film unit is not provided with a flash device. A photo film having ISO sensitivity of 1600 or above is preloaded in the lens-fitted photo film unit in a factory. An exposure device has a large-exposure amount mode and a small-exposure amount mode. In the large-exposure amount mode, appropriate exposure can be given to a subject when an exposure value at ISO 100 is less than 8. A mode switching operation member selects the large-exposure amount mode or the small-exposure amount mode.

Description

technical field [0001] FIELD OF THE INVENTION The present invention relates to a lens-fitted photo film unit suitable for photographing low-brightness subjects without a flash. Background technique [0002] Various lens-fitted photo film units preloaded with photo film are known. For example, there are lens-fitted photo film units with a built-in flash that enables shooting in a dark room. Meanwhile, there is a mode switching type lens-fitted photo film unit capable of shooting outdoors in bright places such as daytime and outdoors in dark places such as darkrooms and outdoors at night by selecting a shooting mode corresponding to shooting conditions. In the mode-switching type lens-fitted photo film unit, the background of dark places is recorded vividly by using high-sensitivity photo film. [0003] In a lens-fitted photo film unit with a flash unit, if a high-sensitivity photo film of ISO800 is used, the shutter speed is set to 1 / 140 second and the aperture number is se...
