Early prints, Albumen and POP papers, use silver chloride as the light
sensitive material. It is not as sensitive as silver bromide or silver
iodide (the other two main silver salts), the advantage is the image is
not dependent on developer it appears with exposure to uv light ( the
sun). The image that results is a deep purple before it is fixed, when
fixed it becomes a brick reddish brown (not very atractive) it is
usually toned in a gold toner which changes the colour to a range of
purple brown to a warm black. It works the opposite to present papers
that turn from black to brown.
Rapid selenium toner gives a more accurate representation of the early
prints. The best results are to use Printing Out Paper available from
the Chicago Albumen Works.
