One photography historian claimed that "the earliest exponent of 'Fine Art' or composition photography was John Edwin Mayall, "who exhibited daguerrotypes illustrating the Lord's Prayer in 1851".
Sarah Helen Whitman correspondence with Ingram, with her letters from Poe and a daguerrotype portrait, was added to the library of material he was assembling; Ingram's Poe collection is now held at the Albert and Shirley Small Special Collections Library at the University of Virginia.
