Abstract

A lens-fitted photo film unit includes a flash unit for applying flash light to a photographic object. An exposure amount changer, such as an aperture stop changing mechanism, changes over object light incident on photo film from the object between low and high exposure amounts. For the lens-fitted photo film unit, a photographic mode selection device includes a movable selector, such as a button, for selectively designating a daylight mode, a daylight flash mode and a night flash mode. The movable selector, when the daylight mode is designated, determines the low exposure amount and turns off the flash unit, and when the daylight flash mode is designated, determines the low exposure amount and turns on the flash unit, and when the night flash mode is designated, determines the high exposure amount and turns on the flash unit.
