Portrait of a member of the Women's Auxiliary Air Force (WAAF), Australia 29 June 1942, detail of original photographic negative, ON 388/Box 076/Item 007 collection.sl.nsw.gov.au/record/1xqZ6K6Y The purple hue and beautiful mottled effect on this image are both caused by deterioration of the original photographic negative. Called channeling, the net-like pattern is caused by the contraction and deterioration of the cellulose layer in acetate film negatives. The purple hue has been caused by the fading of the other colours in the original negative.
