A diffuser-reflector assembly for use with a photographic flash lamp (800) comprises, in one aspect, an elastic base (100) having rigid first inserts (125 and 130), two arms (105 and 110), a shaft (135), a pivot assembly (150), and one or more frames (116, 121) that hold second inserts (115, 120). The diffuser-reflector assembly installs slidably onto the light-emitting end of a flash lamp (800). The second inserts can have various optical properties. They can be specular or diffuse reflectors, color or neutral density filters, or a combination. The frames and inserts can be swung on the arms and independently pivoted over a wide range of angles above the lamp, thereby providing a wide range of lighting effects. The frames and arms are held in place by friction and can be adjusted by manual force. The entire assembly can be made of simple parts that snap together.
