Abstract
A lens-fitted photo film unit for photographing an object includes a flash charger button as mode selector, which designates a selected one of a flashless mode and a flashing mode. An exposure aperture forms a color image by object light from the object. The image, if the flashless mode is designated, is recorded with first color balance in the exposure aperture, and if the flashing mode is designated, is recorded with second color balance. An electronic flash unit applies flash light to the object. A light balancing filter as color balance adjustor subjects the object light to correction if the flashless mode is designated, so as to set the first and second color balance substantially equal to one another.
