Thus in Edmond Becquerel showed at the Academy of Sciences of color photographic prints obtained, which rendered the Lippmann communications Despite these positive results, traffic to Becquerel, confirmed by those Nièpce POITVIN Saint-Victor, left incredulous public. The discovery of a color photography process was announced too often concealed end always has some clever trap trickery intended to give naive considerable sums for realization of large photographic oeu. We know that i think of Hill experience. This American claimed it defines ement, to issue photograph color shades unalterable.
Ialheureusement has little indication of its process remained secret doubts the reality of the invention yet seem not to have to stand before the Office of the Commission report Washington patents, reproduced in American V Polytechnical Journal page. One of the most interesting work on color photography was curious study Zenker Lehrbuch der photochromy published republished by Schwalbe.

That the re is not only valuable because many historic indications precise description of a practical method photochromy, but mostly because of the theories expressed by the author rationale of colors obtained.
Until Seebeck, Herschel had POITVIN in coloration research paper buy online phenomena under-silver chloride oxidations of the most sensitive layer less pronounced reductions, known ant color rays that touch. Ross had issued from the assumption that the colors could be due to less training more slender silver blades, increasing the thickness of the blade with actinic rays considered to duration of exposure.
Alais Zenker hence viewpoint that the image keeps shades it takes early exposure, concludes that since time already, for each color, corresponding thin blade must have maintain a determined thickness proportional to colored ray wavelength that gave it birth.
The question for Zenker, does not demonstrate that the color images are photochromic colorations thin sections, but rather to explain how i Dingky's JournaJ page. these thin blades can arise. This is for him, least show why produce colors identical to the model to consider the theoretical considerations help explain how thin sections may have a constant thickness for each color. Zenker then emits a very interesting hypothesis fertile starting point of view that arr ant ray of chlorine compound covered silver plate reflected on metallic mirror interfere to result in standing waves admits impressed in plate laminations thin silver layers, keeping somehow the impression of light rays. This laminated layer is made very thin whole surfaces separated by equal intervals to wave demrlongueur has' ant impressed each of the points considered. Looking at an image similar to ordinary light, it remains visible all the radiation contained in white light falling under appropriate angle plate, the only radiation whose wavelengths correspond to light rays that produced stratified layer We see Zenker already now how these considerations lead us to progress ement color photographic processes based on voluntary standing wave reproduction. But before addressing Lippmann process, we have to throw a glance on the important custom writers work Wiener, which depends.

In Wiener takes the Zenker studies, abandoned for thirty years by scientific concerns referred to other problems, disclose a series work published in the Annalen i Wiedemann, correctness of the assumptions made by Zenker about staining observed on the plate 'chlorinated silver, prepared according to process Becquerel. also gives a very curious explanation purpose color on paper, case study writing services that Zenker theory unable to explain.

Wiener, produce colors by photochromatic substances spread on non-reflective supports, is carried by a color selection more resistant to radiation they are exposed. The silver professional letter writing service chloride sub-must be considered to be constituted by mixing various shades different body. This is one of the substances which color corresponds to color range which it is struck, which, reflective beam absorbs minimum is consequently less affected. We are thus confronted with the phenomenon of adaptation with certain analogies with the phenomena observed by zoologists designated by name mimicry. Among other substances found in skin certain caterpillars, behave in a similar way sub-chloride The Wiener explanation was not entirely new Becquerel effect, compared already phenomena discoloration best writing service reviews phenomenon in sub-silver chloride acoustic ghostwriting services and conceded a series colored materials in one photochromic substance each such material could be likened to a rope, hit by several sounds at once put only motion by ibration whose height corresponds to the natural vibration. I Colson, after playing, next Wiener work, experiences his predecessors, serving papers blackening direct trade, was also of the opinion that we can explain production of colorations high quality article writing service admitting that molecular motion products that tend to form starts to unison different kinds of radiation received thereby comprises infinite variety Wiener the hypothesis was experimentally by ériftée i CocsTET.
