ABSTRACT:
A flexible mounting band with means for attachment to a camera and shade pieces, the shade pieces being made of opaque, flexible, plastic sheet material. A top shade piece attaches to the mounting band and extends outward from above the camera lens, adjustable over a range of angles. Two side shade pieces are attached to the top shade piece and are adjustable in angle to the top piece and in lateral distance therefrom for fitting a variety of camera lens widths. A hinge means is formed in the top shade piece and side shade pieces for angle adjustment, whereby each piece can be adjusted independently to obtain a desired lighting effect. A visor extends forward from the top shade piece and rear screening sections extend rearward from the side shade pieces to further control the light entering the camera lens. When dismantled, the shade apparatus is configured into an easily portable bundle of shade pieces securely wrapped with the mounting band.
