To make 100 sheets of albumen paper — paper coated with a solution of egg white and silver nitrate — required cracking 100 dozen eggs and separating the yolks.

If one does not have an actinometer, a slip of albumen paper may be used; as soon as the paper has reached the darkest point, which is then called one tint, extend it so that a fresh portion comes out to the light, and so on for the different tints.

The gelatine papers have almost entirely taken the place of the albumen paper, a paper which was always hard for the amateur to handle.

Fuming albumen paper makes it easier to print and tone.

The keeping quality of the prepared paper is remarkable; it has been kept for two years without apparent change; its sensitiveness is at least one-third greater than that of silver albumen paper.
