The taking away, or subtractive, techniques were used by J. M. W. Turner used, and by the summer of 1870 well-documented in 19th-century artists books. In contrast, Ruskin was opposed to such techniques, lecturing against the use of sponges and textured paper. A number of the paintings in the sketchbook are executed on textured paper and Sargent made various uses of the textures. For example Frau von Allmen and a companion shows areas of textured paper left unpainted to highlight reflections in on the objects in the chalet's interior. Jungfrau is painted on blue paper; the mountain is rendered in Chinese White, although he resorted to the older and more traditional lead white to render snow elsewhere, such as Mt. Pilatus.
