An object to be photographed is illuminated with substantially omni-directional, glare-free lighting. The object is placed within an ovoidal shell, inward from an access opening at one end, and supported on a platform formed by a flattened bottom surface of the shell. The entire inner surface of the shell is a light-diffusing surface and is illuminated by a light source which is shielded from direct illumination of the object. The ovoidal diffusing surface reflects light back and forth from and onto itself to produce substantially uniform omni-directional illumination within the shell. The object is supported far enough inward from the access opening of the shell to receive such omni-directional illumination so that it is well lighted for photographing and, in the absence of direct-lighting illumination, appears substantially glare-free. Any highlights desired for photographic purposes are produced by direct lighting from a suitable source, as by controlled direct lighting from the main light source or from a supplemental lamp.
A method and apparatus for diffusing light to photograph an object. A cover is placed over an object and surrounds the object. The cover is made of translucent material that diffuses light from outside of the cover and minimizes shadows cast by the object. A lens of a camera fits through an opening proximate a top of the cover to photograph the object.
A photographic cove for use in photographic studios and the like comprises a plurality of portable pre-fabricated modular units (1) each having a front surface (2), which in some units is concave, and mating side surfaces (3). The units (1) are releasably secured together by means (7, 8 or 10, 11). Means (5, 14 or 20) support the assembled cove.
When examing visually uneven surfaces the problem is the disappearing of the areas remaining in the shade from the picture. To the lighting device in accordance wiht the invention for illumination of and elimination of shades from uneven surface (1) belong a source of light (2), a mainly globular reflecting contrivance (3), the interior surface of which is equipped with reflecting material, and to which openings (4, 5) for the examining of the surface and holes (6) for conducting of the light into the reflecting contrivance are formed, as well as a reflector element (7) for reflecting of light through the opening (4) into the reflecting contrivance.
A combination light assembly includes a light source within a casing that is detachably mounted to a housing with a quick connect assembly. The housing has a curved rear wall and a front area having an upper opening and a lower opening. The casing is mounted to the housing so that the light source will emit light into the housing through the lower opening for reflection off the curved rear wall and out the upper opening. The quick connect assembly comprises posts extending from the casing and connector plates positioned behind attachment openings in a framework that encloses a portion of the front area. The connector plates have flex openings that expand to engage the posts. The casing is attached by moving the posts through the attachment openings and into the flex openings.
A method and apparatus for photographic illumination comprising a light box having a top surface with spaced apart walls depending therefrom having an aperture in one wall thereby forming a chamber for the placement therein of an article or articles to be photographed and wherein said light box material is light diffusing. The method further comprises a camera mountable apparatus having means for securing said apparatus to a camera, means for producing illumination, means for producing light beams including fiber optics and multiple LEDs, means for varying the number of beams projected onto the photographic subject. The present invention uses two different light sources, for the photography of gemstones or the like.
