Abstract
A flash camera with glare controlling ability for general photographic use is described. It includes at least two panchromatic reflective sheet polarizing filters. One filter is incorporated in the flash unit to produce a polarized light flash source. The flash source also incorporates light redirecting means such that a majority of light from the flash is directed toward the photographic scene. A second filter over the camera lens excludes that light originating from the flash source which is specularly reflected from the photographic scene.
