The Slums of Glasgow

In 1866 Annan purchased for Scotland the patent rights to Joseph Swan’s permanent carbon process to improve the photographic art reproductions he specialized in. As it turned out, his fame rests on the series of slums and alleys of Glasgow that he documented on commission from the Glasgow City Improvement Trust as of 1868. In 1877 he printed 60 sets (of the series of 40 photographs) as carbon prints.
