He was unable to get his travel writing published; after a short spell in the United States, where he failed to find work during the Depression, Rodger returned to Britain in 1936.
He was probably the only British war reporter/photographer allowed to write a story on the Burma Road by travelling on it into China, with special permission from the Chinese military.
His photographs of the survivors and piles of corpses were published in Life and Time magazines and were highly influential in showing the reality of the death camps.
Rodger later recalled how, after spending several hours at the camp, he was appalled to realise that he had spent most of the time looking for graphically pleasing compositions of the piles of bodies lying among the trees and buildings.
His photographs made in 1948 and 1949 of indigenous people of the Nuba mountains, in the Sudanese province of Kordofan, and the Latuka and other tribes of southern Sudan, have been called "some of the most historically important and influential images taken in sub-Saharan Africa during the twentieth century".
[4] As Rodger wrote several years later, "When we came to leave the Nuba Jebels (mountains), we took with us only memories of a people ... so much more hospitable, chivalrous and gracious than many of us who live in the 'Dark Continents' outside Africa.
