The whole thing is made up by the blogger who wrote this post at the guardian.com and wants to promote himself at HN, and the format of the article my suspicion even more clear to me. Young people with interest by photography will still know about these things because they will buy an analog camera and become what we call “hypsters” nowadays (the equivalent of “nerds” back then). And back then also not everyone knew or could go through the whole negative reveal process, as much as nowadays not everyone can format a hard disk and install an OS.
