Abstract
Abstract A reflector apparatus for reflecting light produced by a flash light apparatus such as a flash bulb, an electronic flash apparatus or the like, comprises a sealable container capable of tightly containing a gas therein. The container is in the form of a substantially spherical configuration when inflated and is made of a soft and flexible material, a half portion of which is transparent while the other half portion reflects light. The light rays from the flash apparatus are transmitted through the transparent portion and are reflected by the reflecting portion toward an object to be illuminated.
