First plates 1828

[bailun]

Ladies and gentlemen!

 

Here the information from Russian archive / such exists / DAGUERRE and NIEPCE.

It is one of the first orders of the silver polished plates for a photo.

On July, 2 1828. letter of engineer V.Chevalier / Paris to N.Niepce/Chalons-sur-Saone.

Chevalier informs that has sent plates Niepce and writes the price.

Dag it is not yet open. But work in this direction already went.

For all modern problems with search good and not expensive silver plates are known.

This problem exists a minimum with 1828. in letters the previous sending of plates on June, 5 1828 mentions.

We can compare the prices in view of inflation of 19 centuries. Here there are economists?

 

4 plates of superimposed silver – 37,95 F

Polishing of 2 plates on 1.5 F – 3 F

Polishing of 4 plates on 1.5 F – 6 F

All – 46.95 F

 

Gratitude France and Paris who have presented the world a photo. Also the first here have appeared platers.

Name of the first mr Balaine!

 

Applause!

The plates would have been for Niepce’s process, the physautotype, not for the daguerreotype. It was very different from the Daguerreotype , he used iodine to blacken exposed portions of silver on a plate, post exposure and partial development. Daguerre’s approach was different of course, using Iodine as a sensitising agent, his discovery and use of latent image development and of course the stumbling block that most would-be inventors of photography struggled with, he halted the action of the light sensitive silver salts post development by fixing the plate in a saturated salt solution. His initial version of the process did have very long exposures but they were much better the physautotype’s which were several hours. The plates mentioned in the letter above probably bore photomechanical images rather than images from nature. Niepce like Talbot was more concerned with a process that would allow for the mass reproduction of images. Daguerre’s aspiration was less mundane and sort the perfection he could see in a mirror.

Pardon, Alan!

I did not write that a plate for daguerreotype.

Up to daguerreotype 10 more years remained, on other sources 8.

These are known things.

These are plates for continuation of experiences Geliograph if to be exact.

physautotype will be then.

Then – daguerreotype.

For now it is one of the first order for the polished silver copper plates.

Which we use now.
