The estimation of correct exposure is a difficult matter for many beginners in mountaineering photography. The following may serve as a rough guide. In the summer months between the hours of 9 a.m. and 5 p.m., when above the snow-line, snow scenes require ¹⁄₅₀ of a second and about stop f: 20; rock scenes ¹⁄₅₀ of a second, stop f: 10. Distant snow scenes and distant mountain ranges need ¹⁄₅₀ of a second, stop f: 30. I do not recommend exposure meters, chiefly because their use takes up too much time. For development, I advocate the use of Kodak daylight developing tanks with the special developers prepared by that firm. The negative of almost every photograph used in the illustration of the present book was developed in the Kodak daylight developing tank.
