Reiss was born in 1927 in Hamburg, Germany to Danish parents. He began taking photos as a child. The family moved to the United Kingdom in 1936. There he attended Oundle School, and began taking photos.

Reiss began working for Picture Post magazine in the UK at the age of 17, the youngest staff photographer employed by them. Picture Post published over 60 picture stories by him. In 1947, Reiss sailed for New York and immediately started working for LIFE magazine. In 1950, realising he had gone stale, Reiss quit photography, and entered the wool trade.

Not until 1993, ten years after migrating to Australia and receiving a chance commission from James Mollison did he return to photography.^{[citation needed]} Reiss died on 4 December 2017 at the age of 90.
