After being questioned by an online reader, the Chicago Tribune published an explanation for a 1955 photo of former Mayor Richard J. Daley that appeared in their Almanac section featuring photos from their archives. The reader noticed what appeared to be the line of a felt-tip marker highlighting the edge of the mayor’s hand. The newspaper explained that this line was Spotone ink which was applied to enhance contrast to the image in preparation for print production—which in those days could not reproduce photos with as much detail. Because the newspaper no longer had the original negative, they reproduced the version that had been retouched in the 1950’s. Though such retouching was standard practice in 1955, the fact that it seemed so obviously inappropriate in 2012 illustrates that ethical standards necessarily shift as technology evolves.
