All professional photographers practice the silver printing process with more or less of success, as they bestow care and intelligence in the working and are zealous for the reputation of their work.

The proper handling of a negative by the printer requires as much study and skill on his part as does the posing and lighting of the subject in the studio; and the printing room should be as replete with every convenience for forwarding and improving the operations therein conducted, as any other department of the establishment.

This room is generally situated at the top of the house, and wherever situated, should be so arranged that the east, south and west sides may be opened to the sun, that his direct rays may be utilized from the earliest to the latest working hours. Part of the room should be partitioned off in such a manner, and illuminated in such a moderate degree, that the sensitized paper may not suffer from excess of light while the frames are being filled and the changes made.

The printing room outfit consists of the various sizes of printing frames, cardboard, tissue paper and cottonwool for vignetting, and knives, long-blade scissors, and glass forms for cutting the paper to various sizes, light tight drawers to hold the prepared paper, shelves, and racks for the negatives.

Mucilage or paste and brushes.

Flat brushes for removing dust from negatives.

India ink and Opaque, with pencil brushes and lead pencils for spotting negatives.

The Silvering Room

The silvering room may be also used for other manipulations in the process, such as fuming the paper and washing the prints, and should be furnished with all the conveniences for such work, which consist of

Nitrate of Silver.

Albumenized and plain paper.

A flat dish to hold the silver solution, of the size of the largest paper to be floated.

A fuming box.

A bottle of concentrated Ammonia.

A gas or oil stove for drying the paper.

A dozen or more of Lockwood's patent photo clips.

Bi-Carbonate of Soda.

An Argento meter.

A 16 oz. Graduate.

A clock.

One agate evaporating dish, and 2 or 3 wide-mouth glass bottles, that will hold the full quantity of silver solution in use.

The Silver Solution For Paper

A plain silver solution, of a strength of 30 grains of nitrate of silver to the ounce of water in hot weather, increasing to 60 grains in the coldest, with enough bicarbonate of soda added from time to time to keep a small sediment of carbonate of silver in the bottom of the bottle or dish, is all that can be desired as a silvering solution for albumen paper. It only needs to be kept up to the proper strength by the addition of silver nitrate and water, when required; and when it shows signs of discoloration a little more soda and an hour's sunlight will keep it in good order the year round.
