in the
Himalayas, taken from the
Zemu Glacier The high quality of Sella's photography was in part due to his use of 30×40 cm
photographic plates, in spite of the difficulty of carrying bulky and fragile equipment into remote places. He had to invent equipment, including modified
pack saddles and
rucksacks, to allow these particularly large glass plates to be transported safely. His photographs were widely published and exhibited, and highly praised;
Ansel Adams, who saw thirty-one that Sella had presented to the US
Sierra Club, said they inspired "a definitely religious awe". Many of the photographs he took were of mountains which had not been previously recorded and so have historical as well as artistic significance; for example by recording the
retreat of glaciers in the Rwenzori mountains in Central Africa. ==Death and legacy==
