A camera with a retractable electronic flash assembly is provided with a cam member having a first cam face for moving the flash assembly and a second cam face for moving a flashtube in the flash assembly. The cam member is moved within a first moving range to move the flash assembly, and the cam member is moved within a second moving range to move the flashtube. Thus, a moving mechanism of the flash assembly and the flashtube can be simplified.

An image capture apparatus includes: an image capture optical system; a rotary device rotatable from an initial position in a first direction and rotatable from the initial position in a second direction; a protective cover that performs an opening action to expose (uncover) the image capture optical system in response to rotation of the rotary device from the initial position in the first direction, and that performs a closing action to cover the image capture optical system in response to rotation of the rotary device from the initial position in the second direction; and an energizing member that returns the rotary device to the initial position.

A folding softbox is disclosed including a collapsible frame that is provided in a manner of an umbrella frame, i.e., a central post with ribs that projects outwardly from a first end of the post and curve toward a second end of the post. A strut extends between a mid-span portion of each rib and the post to hold the ribs away from the post in an operative position. The inner ends of the struts are interconnected and are selectively slidable coaxially about the post. When the inner ends of the struts are slid toward the second end of the post, the outer ends of the struts are pulled inwardly toward the post and, thus, pull the ribs inwardly toward the post into a second or collapsed position. The folding softbox includes a mounting apparatus adapted for releasably connecting to any of a wide variety of light sources.

A lighting box or front projection light device has a housing with an open front and open rear and a bar or rod extending horizontally across the housing. Multiple stage-type nonfocusable lights such as par lamps are mounted on the bar and positioned to send light out the front of the box. The box also has a diffusion element holder (frame) disposed proximate its front end, and even may have multiple diffusion element holders including having one diffusion element holder at an angle. Each diffusion element holder has a diffusion element or filter. The diffusion element or elements receive the light from the lighting instruments and diffuse it to provide a soft projected light from the box. In accordance with one aspect of the invention, this light may be used to provide diffused light as part of the key lighting for a stage or set, and may provide such soft projected lighting from a front (downstage) of the stage or set.

A compact lighting device or a strobe device includes a discharge tube; a prism unit having an incident surface receiving a light from said discharge tube and an outgoing surface that ejects an incident light to a side of an object to be photographed; and a first optical unit and a second optical unit disposed on said prism unit on the side of the object to be photographed; wherein a relative interval between said first optical unit and said second optical unit are change to vary a irradiating angle of the light directed toward the object to be photographed.

A light emission device having therein a light emission tube which is almost straight in shape and emits light in a radial manner and a reflection shade that reflects light emitted from the light emission tube toward an object, wherein the reflection shade has a reflection surface in which light emitted from the light emission tube in the direction opposite to the direction from the center of the light emission tube to an object and reflected on the reflection shade does not interfere with the light emission tube.

A portable light reflector or diffusor includes a reflection or diffusion cloth attached to a foldable framework composed of longitudinal struts and a transverse strut which is stiff with respect to compression and connects the two longitudinal struts, wherein the transverse strut has ends bent in the direction towards the plane defined by the longitudinal struts and the reflection or diffusion cloth attached to the longitudinal struts, wherein the angle between the bent ends and the intermediate piece between the ends is greater than 90°. A belt extends parallel to the transverse strut in such a way that the longitudinal struts are pressed apart for tensioning the reflection or diffusion cloth.

An improved process of matching the color of a paint to the pre-existing color of a vehicle is provided. The process includes the steps of exposing a photo-reactive film to the surface of the vehicle whose paint color is to be matched. Once exposed, pigments in the film are activated to mimic precisely the color of the vehicle. The pigments are then extracted, isolated and mixed with a neutral base paint solution, which is tinted by the pigments to match the color of the vehicle. The tinted and matched solution is used for painting or touch-up work on the vehicle.

A camera is provided, which can appropriately control the electronic flash irradiation area when the electronic flash device capable of setting its irradiation angle in a plurality of ways is used as an AF auxiliary light source, thus improving the use efficiency of the auxiliary light and reducing wasteful energy consumption. In the camera of the present invention, the control unit automatically controls an electronic flash irradiation angle to the narrow electronic flash emitting unit regardless of the imaging angle which was set, while performing the distance measurement operation in cooperation with the electronic flash.

Apparatus for use with a light source including a ring reflector having an rim projecting outwardly from the light source for directing light from the source in a first direction, includes, a support, and a frame connected to the support and adapted to extend over the ring reflector to support a sheet of material in a position relative to the light source to redirect a substantial portion of the light from said first direction to a second direction. The support is coupled to the light source by a strap having two leg portions joined together by a bight portion, the two leg portions terminating at a first end coupled to the support so that the leg portions extend laterally on opposite sides of the ring reflector, each leg portion including a longitudinal slot for engaging said rim, the bight portion spacing the leg portions from each other by a distance less than a diameter of said rim, the leg portions being elastically displaceable to a distance greater than said diameter for engagement with the rim so that the apparatus is coupled in operative position relative to the light source.
