Pugahm Myo: Thapinyu Pagoda, August 20?24, 1855, Image: 25. 1 x 34. 5 cm (9 7/8 x 13 9/16 in. ), Photographs, Linnaeus Tripe (British, Devonport (Plymouth Dock) 1822?1902 Devonport), Here the Thapinyu Pagoda, the tallest structure at Pugahm Myo, rises toward a cloudy sky. Because early negatives were overly sensitive to blue, clouds were difficult to photograph. To evoke them and other atmospheric effects, Tripe retouched his negatives by applying pigment in thin layers, gradually building up density and form with highlights and shadows
