During his lifetime Vittorio Sella was celebrated for the photographs he exhibited from his daring expeditions. According to one reviewer, his annual exhibition of mountain photographs at the Alpine Club in London was "inconveniently crowded". Sella sold his prints to people from Italy, France, Germany, and England, and was represented by a London dealer named Spooner. His photographs satisfied a growing public hunger to know more about distant places on the earth that few would ever see first-hand, while providing a satisfying blend of artistic, scientific, intellectual, and even spiritual elements. Sella's primary goal was to provide the empirical evidence of what he and his party had seen on their expeditions, and to convey reality as it was perceived by the human eye. His approach was governed by rigorous technical and aesthetic standards that he called "la realta severe" - severe reality.
