The plate is then exposed and the latent image developed by an aqueous solution of pyrogallic acid, or protosulphate of iron.
The exposure is made and the latent image remains upon the sensitized plate, which is again used to photograph the sitter.
The latent image impressed on the plate is brought out or developed by exposing the plate to the action of the vapour of mercury.
In order to make the latent image appear, it is only necessary to immerse the print in a weak five-per-cent.
The latent image arising from X-rays is next in order of increasing stability.
The silver particles held this image, but not visibly—it is a latent image, and it is the purpose of development to bring it out.
Like true artists, we no longer scorn the material forces, but see in them all the latent image of the divine.
It is the particular business of a chemical called “pyro” to release this latent image.
I did not realize the master fact that the latent image which had been developed was the basis of photographic manipulation.
