Record 4 2012-10-16

English

Subject field(s)
  • Photography
DEF

The formation of a positive image on a developed photographic plate or film exposed to diffuse light...

CONT

When a partly developed image is briefly exposed to actinic light, the final developed image becomes reversed. This is because in areas where the negative image had started to form, the emulsion is desensitized by the oxidation products of development. The result is that the extra exposure affects only the shadow areas of the original negative so that the final image is a positive. This type of reversal is known as the Sabattier effect, after its discoverer.

OBS

... the image is formed by exposure of silver halide in undeveloped regions of the emulsion.

French

Domaine(s)
  • Photographie
DEF

[...] technique photographique particulière qui permet de souligner les contours et d'inverser certaines valeurs [...]

OBS

Ce procédé [«effet Sabattier»], communément appelé, d'une manière impropre, «solarisation», donne à l'épreuve les qualités d'un négatif et d'un positif conjugués. Il ajoute également des lisérés dégradés par inversion [...] Strictement parlant, cette technique de tirage n'a rien de commun avec une solarisation. La véritable solarisation intervient lorsque le film, et non le papier de tirage, est fortement surexposé. Cette forte surexposition engendre une réaction curieuse et complexe dans les cristaux sensibles, qui renverse pratiquement le mécanisme de la photographie normale; l'image apparaît en positif et non plus en négatif.

Early in 1995, a steering committee of Paramedics began the ambulance task of creating a legal and administrative structure for the Ontario Paramedic Association. The professional association is a registered ’not for profit’ organization representing Paramedics across the province. Since it formation, the OPA has worked to enhance the professional image of paramedics, to improve communications between paramedics, and to lobby for improvements to the standards of patient care. Our mission is to provide leadership for Paramedics and to promote the art and science of Paramedicine. We serve Paramedics and their patients by advocating the highest ethical, educational, and clinical standards for the protection of Paramedicine.

Imagery Exploitation System (IES). Modernized Imagery Exploitation System (MIES). MIES is a Corps and EAC tactical imagery exploitation system capable of receiving, processing, and disseminating national and theater imagery. The MIES provides first phase imagery exploitation for the Indications and Warnings (I&W) missions of Army users. The system provides IMINT reports and Secondary Imagery Dissemination (SID) through an extensive communications section. It travels with its own satellite communications (SATCOM) system that provides the relayed national imagery through the Defense Dissemination System (DDS).

CONT

The imagery Exploitation System/Balanced Technology Initiative(IES/BTI) is a first phase near-real time image exploitation system to support Army Corps intelligence and electronic warfare(IEW) situation development, target development and target acquisition. IES/BTI exploits synthetic aperture radar(SAR) and infrared(IR) imagery and annotates the presence and type(artillery, armor, etc) of military units(company size and above). IES/BTI employs a hierarchical reasoning paradigm, using Bayesian inference for hypotheses management and belief propagation to solve the complex force/terrain/military situation and formation.

... the image silver is embedded in a thin layer that may consist of albumen, collodin, or gelatin.

CONT

In the chromogenic processes, three selectively light sensitive layers in the silver halide emulsion are exposed to light. Initially, a black and white, silver halide, latent image is chemically developed to form a negative on all three layers. During this stage, the developer used to convert the exposed silver halide to metallic silver becomes oxidized. The oxidized developer combines with color couplers initiating the selective formation of cyan, magenta and yellow dyes within discrete layers of the emulsion. The image silver is then bleached and unexposed silver halide is removed by fixing.

One of the best studied radio galaxies, this image is composed of a very smooth cigar-shaped emission region closely aligned with the radio axis, upon which is superimposed a string of bright knots that might be stars or dust. This suggests that a jet of high speed gas, presumably ejected from a black hole at the core of the galaxy, might be triggering star formation along its path.

La critique de la ville nébuleuse. En général on attribue quatre grands types de reproches à cette forme de décentralisation périphérique : 1. manque de structure : l'illisibilité et la fragmentation. La ville a toujours été construite par interventions successives. La confrontation obligée de ces fragments disparates à l'intérieur d'un cadre morphologique contraignant y engendre néanmoins, une complexité et une intensité qui confèrent à l'ensemble une indéniable plus-value. En mettant en contact ces éléments hétérogènes et en les intégrant dans un ensemble ordonnateur, la ville crée une nouvelle unité au sein de laquelle ils tissent entre eux des relations originales et inattendues.
