. Portrait . on Image Spoiled UntreatedDesiccated 6 hours22 hoursy^ hour 12 to 16 hours Humidified 4 to 5 hours Looking over the preceding facts the following infer-ences may be drawn: 1. That it is important to keep paper stored in areasonably dry place. 2. That the effect of humidity is to increase theactivity of the chlorides as an oxidizing agent, resultingin the partial or total destruction of the latent image. 3. That prints should be developed immediatelyafter exposure or as soon after as may be possible. We have tested all the developing papers on themarket with quality for portraiture

We have tested all the developing papers on themarket with quality for portraiture, and the regressionof the image is, if anything, greater than with , when a photographer is having paper troubleshe should ascertain the humidifying conditions of theroom in which the paper is kept, and if too humid, heshould dry the paper. The photographer should alsobear in mind that better prints result when develop-ment takes place immediately or very soon after makingthe exposure. PORTRAIT.
