Almost all conventional acid filter dyes can be rendered nondiffusing in emulsion or thin auxiliary layers, without lowering their phys.-mech. properties or interference with their bleachability or washing-out during processing by a small amt. of a mordant ...
We present a study of radiometric calibration and the in-camera imaging process through an extensive analysis of more than 10,000 images from over 30 cameras. The goal is to investigate if image values can be transformed to physically meaningful values and ...
Digital camera sensors are sensitive to wavelengths ranging from the ultraviolet (200-400nm) to the near-infrared (700-100nm) bands. This range is, however, reduced because the aim of photographic cameras is to capture and reproduce the visible spectrum (4 ...
Digitally, panoramic pictures can be assembled from several individual, overlapping photographs. While the geometric alignment of these photographs has retained a lot of attention from the computer vision community, the mapping of colour, i.e. the correcti ...
This comprehensive treatise, featuring the history and historical processes of photography, contemporary applications, and the new and evolving digital technologies, will provide the most accurate technical synopsis of the current, as well as early worlds ...
The present invention provides an image forming apparatus (210) as well as a developing cartridge (240) for use in an image forming apparatus, wherein a contact plate of an electrode (247) of the developing catridge is disposed to contact a bias terminal ( ...
Managers of photographic collections in libraries and archives are exploring digital image database systems, but they usually have few sources of technical guidance and analysis available. Correctly digitizing photographs puts high demands on the imaging s ...
A photog. material with improved physicomech. properties and photog. characteristics contains a combination of gelatin and a water-sol. polymer in the form of a symplex. Thus, a cellulose acetate support was coated with a coupler-contg. Ag(Br,Cl,I) (15 mol ...
We study a new image sensor that is reminiscent of traditional photographic film. Each pixel in the sensor has a binary response, giving only a one-bit quantized measurement of the local light intensity. To analyze its performance, we formulate the oversam ...
