Before leaving his practice to go to Africa, famed Hollywood cinematographer
James Wong Howe had given Treutle three short lessons on cinematography. When Treutle returned in the summer of 1952, Howe viewed the 10,000 feet of color film that Treutle had shot and was impressed enough to tell the dentist, "There is not a cameraman in Hollywood who would have, or could have, gotten what you have here. You have succeeded with some shots that I would have passed up for a number of technical reasons as being impractical to attempt.".
