In handling bromide paper you must be almost as careful as you are with dry plates or films. Before making a picture it is a good scheme to test the length of time to expose the paper. To do this take a sheet of bromide paper and cut it into strips 1 inch wide and 10 inches long; fasten a strip at a time diagonally across the board and expose the first one for say 5 minutes and then develop it, when you can usually tell about how long the exposure should be.
A Developer for Bromide Paper.
—A good stock solution developer for bromide paper, velox paper, films and dry plates can be made by adding these chemicals to 25 ounces of hot water in the order named and stirring in each one until it is dissolved; elon ¹⁄₈ ounce; desiccated sulphite of soda 1⁷⁄₈ ounces; hydrochinon ¹⁄₂ ounce; desiccated carbonate of soda 5¹⁄₄ ounces; potassium bromide 30 grains and wood alcohol 3 ounces.

This developer will keep for a long time if the bottle containing it is kept full, otherwise the air will act on it. To develop six 8 × 10 bromide prints use 1 ounce of the stock solution and 6 ounces of water.
