The Albumen Process

THE ALBUMEN PROCESS.

The albumen process, or the ordinary silver process, as it is usually called by professional photographers, is capable of giving most pleasing results, and deserves to be far more practised by amateurs. In quality of gradation and richness of colour it more than holds its own when compared with its rival, the gelatino chloride process. Although spoken of frequently as old - fashioned, it is still largely used. The paper will stand fairly rough handling, as the sensitive coating is practically insoluble even in V: arm water ; it is free from disagreeable gloss ; it gives a softer set of gradations ; and it is not liable to double-toning. On the whole, the albumen process is cheap and easy to work, and gives highly satisfactory results with negatives showing fine detail. Over exposed negatives and negatives lacking in density cannot be successfully printed in albumen, and this probably accounts for the fact that it has been superseded by gelatino-chloride to such a great extent.

Photographers who prefer an enamelled glaze on their pictures, and who desire an extreme contrast or brilliancy, may not find the albumen process please them so well as the gelatino-chloride process. Al bumen paper can be purchased. Some brands are obtainable in cut sizes. The paper keeps extremely well, but gives off a rather offensive odoir when stale. The chemicals necessary are few, if the paper is purchased ready sensi tised, the chloride of gold. hypo., and borax being all that are required. This borax is in the form of a white powder, and dissolves freely in warm water. The acetate bath may also be used if the paper is treated first of all with a solution of soda carbonate (see section on "Toning with Gold and Platinum ").
