Abstract
Abstract A foldable hood accessory to which a camera may be mounted for photographing electro-luminescent images presented on a reflective surface, the hood including an assembly of upper and lower hood panels pivotally connected to each other at one end and closed along diverging side edges by flexible side shields. The connected hood panels are supported from a plate-like camera mounting base through a pivotal bail and by pivotal connection to a copy lens mount which, in turn is pivoted generally centrally of the base. The pivotal connection of components in the overall assembly permit the hood accessory to be conditioned in a very compact folded form or in an erected form to present a forwardly diverging light shielding hood with a mounting platform at the rear end thereof and to which a camera may be mounted.
