Abstract: A method for depth mapping includes providing a depth mapping device comprising a projector, which is configured to project a pattern of optical radiation onto a target area over a first field of view about a projection axis, and a camera, which is configured to capture images of the target area within a second field of view, narrower than the first field of view, about a camera axis, which is offset transversely relative to the projection axis. The projector projects the pattern onto first and second planes at first and second distances from the camera, and the camera captures first and second reference images containing first and second parts of the pattern on the first and second planes, respectively. The first and second reference images are combined to produce an extended reference image including both the first and second parts of the pattern.

Abstract: A receiving element for use in an additive color photographic diffusion transfer process which comprises a transparent support carrying an additive color screen and a layer comprising noble metal silver precipitating nuclei and a polymer; wherein said nuclei are present in a level of about 0.1-0.3 mgs/ft.sup.2, and said polymer is present at a level of from about 0.5 to 5 times the coverage of said nuclei. Preferably, the noble metal is obtained by reduction of a noble metal salt or complex, and more preferably, the noble metal is palladium.

Abstract: Clusters or galaxies of noble metal silver-precipitating nuclei for use in silver diffusion transfer processes are formed by reducing a noble metal salt or complex to form a colloid of noble metal nuclei and inducing instability to said colloid, whereby said galaxies are formed.

Abstract: Silver diffusion transfer image-receiving elements are formed by hydrolyzing a solution of a hydrolyzable cellulose ester, coating a support with a layer of said hydrolyzed cellulose ester and disposing silver precipitating nuclei therein.

Abstract: Novel image-receiving elements for obtaining photographic images in silver which comprise a support carrying, as a silver precipitating layer, a layer of inorganic stannic oxide polymer (tin hydrosol) having a noble metal reduced thereon.

Abstract: The present invention relates to photography and, more particularly, to a novel radiation recording photographic element which comprises a direct positive photosensitive element which includes, in combination, a particulate dispersion of fogged silver halide crystals, adapted to discharge the fogged silver halide upon exposure to electromagnetic radiation actinic thereto, having associated therewith in electron accepting relationship a semiconductor adapted to accept electrons from said silver halide crystals as a function of the exposure of the crystals to incident electromagnetic radiation actinic thereto.

Abstract: The present invention relates to photography and, more particularly, to a novel radiation recording photographic diffusion transfer process film unit which comprises a photosensitive element which includes, in combination, a particulate dispersion of photosensitive crystals, preferably, photosensitive silver halide crystals adapted to be reduced to silver, upon contact with a silver halide reducing agent, as a function of the crystals' exposure to incident actinic electromagnetic radiation, having associated therewith an inorganic semiconductor adapted to donate electrons to the photosensitive crystals as a function of the exposure of the element to incident actinic electromagnetic radiation.

Abstract: The characteristics of the surface of an article may be modified, e.g., in respect to adhesion, wettability or other physical characteristics, by exposing the surface to an electrical discharge in a mixture of certain gases. The practice of this invention is particularly useful in improving the gelatin adherence characteristics of a photographic film base support.
