"45 three-color Half-tone illustrations from color photographs of Egypt. 163 Half-tone illustrations from B&W photographs of Egypt. A. Miethe [Professor of Photochemistry, Berlin] used a special camera shooting three negatives through filters...[and was] the first to develop true panchromatic emulsions. Professor Miethe took his special camera that exposed successive images on a plate that dropped at the film plane as the three primary filters were placed in front automatically. The earliest example published may be...[Eder's Jahrbuch fur Photographie... of 1903]. This book remains, along with his book on Spitzbergen 1911, the only extensive examples of his special three-color work..."--Hanson Collection catalog, p. 140
