[5] In 1895, Moodie opened a photography studio in Battleford, Saskatchewan, becoming the first woman in the region to do so; she often photographed the area's Indigenous communities.

She frequently accompanied her husband, John Douglas Moodie, on his travels, photographing the Innu people in the area of Hudson Bay (1904–1909).

[7] Many of her photographs were in connection with her husband's work on the Canadian Pacific Railway, accompanying his reports to Prime Minister Wilfrid Laurier and CPR officials.

[2] Her work was part of a 2017 exhibition, See North of Ordinary, The Arctic Photographs of Geraldine and Douglas Moodie, at the Glenbow Museum.

A stamp depicting Moodie's photograph, Koo-tuck-tuck, was issued on 22 March 2013 by Canada Post as part of their Canadian Photography series.
