I was intrigued by the very strong opinions being expressed by Dave Kai-Piper in this week's "Viewpoint" article (p8, 6 April) about the various terms used as shortcuts or slang for "photographer". I don't necessarily disagree with the thrust of his comments but was surprised at the vehemence with which they were expressed. Then I looked at his mug-shot and realised that he seems very, very youthful and, perhaps, not quite conversant with some of the history of the subject. Let's face it - "photographer" is quite a long word and long words do tend to get shortened from laziness or for convenience. "Photographer" also has a very wide range of application and it is quite common to use alternative terms to narrow down the meaning of generic words. Having said that, his principal gripe is with "tog". That is a word that only swam into my ken at some time during the past couple of decades. At first I assumed that it referred specifically to a professional photographer but it now seems to be used more generally. Other terms that Dave mentions (and hates) are "snapper", "clicker" and "button pusher". The latter does seem a derogatory diminution of the photographer's craft but "snapper" has a very long and honourable usage in journalism, particularly press journalism, where we had "snappers" and "scribblers" to differentiate between those who took photographs and those who filed written copy. "Clickers" was a term used by professional photographers to denote those of us who wielded cameras non-professionally. Just to play devil's advocate, I wonder how many of us would ever describe ourselves as "photographers" (despite the title of our favourite weekly magazine)? It does seem a trifle pretentious although I am not above telling anyone who asks about my leisure interests that I am keen on photography.
