Abstract
A camera has a body and a taking lens mounted to the body. The taking lens defines a subject field. A viewing window is joined to the body. The viewing window is transmissive of a light image of the subject field. The viewing window bears a holographic image of a reticle. A light source faces the viewing window and illuminates the holographic image. The reticle produced can be binocularly viewable, that is, viewable by the photographer with both eyes while the photographer looks through the viewing window to compose a scene image for picture taking.
