La Photographie en ballon
This 1911 Paris book, La Photographie en ballon, by Gebhard A. Guyer and published by C. Mendel, is a French photographic treatise on aerial photography taken from balloons. Its plates are rotated monochrome halftone photographs, mostly of mountains and glaciers, and one of a river and town seen from above, showing wide, high-angle views of terrain with snow, cloud and sharp shadow. A designer could take from them the strong graphic contrast of snowfields against dark rock and the abstract patterns that roads, rivers and rooftops make when seen from altitude.
