Niepce De St Victor's Process 1859
Red Prints. Float the paper for fifteen or twenty seconds on a 20 per cent. solution of nitrate of uranium and dry before the fire in the dark room. This paper can be prepared many days before use. Expose in sunshine from eight to ten minut... Preparation Of Red Yellow Or Blue Tissues
Red Tissue.--Dissolve 10 grams of carmine in 1 liter of aqueous ammonia and evaporate. When the smell of the alkali has almost disappeared, add 1 liter of rain water. Of this take 65 cubic centimeters, add 35 c.c.m. of rain water, and in the sol... Printing On Wood Canvas Opal And Transparencies
Printing on Wood.--To print on a wood block a design to be engraved on the same presents certain difficulties. In the first place, the sensitizing solution must not be absorbed by the wood, but remain wholly on its surface; then the photo film, a... The Aniline Process
The aniline process was published in 1865, by Mr. Willis, the inventor of the platinotype.(11) It is based on the oxidation of aniline by chromic acid, thus: A sheet of paper brushed with a solution of potassium bichromate and sulphuric acid, drie... The Black Or Ink Process Ferro-tannate Process
This process gives black positive impressions on white ground from positive cliches, and negative impressions from negative cliches. It has been attributed to Mr. Colas, but in reality it was invented by Mr. Poitevin, who describes it as follows ... The Carbon Process
The carbon tissue is seldom prepared by photographers. However, for the sake of completeness, we shall give the formula of the mixtures most generally employed, and describe the manner of coating the paper on a small scale. Preparation of the T... The Cuprotype Burnett's Process
This process gives positive impressions from negative cliches. Uranic nitrate 10 parts Cupric nitrate 2 parts Water 100 parts Float for a minute strong, well-sized paper on this solution and let it dry spontaneously in the dar... The Cyanofer Pellet's Process
This process gives blue impressions on a white ground from positive cliches, and white impressions on a blue ground from negative cliches. It is termed "positive ferrotype process." The cyanofer is an application of one of the numerous and usefu... The Cyanotype Or Blue Process
This process gives white impressions on a blue ground with diapositives or drawings on transparent or semi-transparent materials, and blue impressions on a white ground from negatives. It is commonly known under the names of "blue print process,"... The Platinotype
This process, discovered by William Willis,(16) yields very fine impressions which wholly consists of platinum and are, therefore, chemically permanent. It has been described theoretically and practically by Pizzighelli and Kuebl in a paper f... The Primuline Or Diazotype Process
Primuline, discovered in 1887 by Mr. A. G. Green, an English chemist, is a dye of a primrose color, possessing a great affinity for cotton fibers, to which it is readily fixed by simply immersing the material for a few moments in a hot solution of... The Uranotype
This process, devised by J. Wothly, in 1864, did not receive from the photographers the attention it merits, as it is always the case when a process is patented, and can be replaced by another equally practical which is not. It gives pictures of ... Tracing Process On Metal
We call the attention of metal engravers to this process. It is well known that wood engravers have their original designs photographed on the block in order to save considerable time by not making the drawing themselves; moreover the cost is nom... X's Process 1865 Secrets Of The Uranotype
Preparation of the Uranium Compound.--Precipitate the nitrate of uranium from its solution by concentrated liquid ammonia. Let settle the precipitate, decant, and wash in several changes of water. Dissolve it by heat in pure nitric acid, taking ...
