Originally posted by victormeldrew A consistent vocabulary across people of any kind is something that has never once happened in the history of language. The beauty of language (particularly English) is that it is quite so fluid and adaptable, but that does mean that between localities, countries, generations and eras, terms can differ significantly, but all the same we can use experience and context to understand easily what each other means.
Unfortunately a lot of people, particularly on forums, feign ignorance to claim that sombody else's use of language is definitively incorrect and that their own is definitively correct, whereas in fact neither can ever be true.
I agree that the fluidity of English is great, but for the clear communication of technical ideas, having a standardized set of terms makes life so much easier. I'm used to textbooks and papers which are consistent within themselves and authors who generally provide the commonly used alternate terms when there isn't a universally accepted standard terminology (and at a minimum provide clear definitions when terms are first introduced). Make no mistake, it was a pipe dream on my part, especially in the context of photography forums

I definitely agree with the feigned ignorance - there's an all-too common tendency to just assume someone else is off their rocker instead of trying to sort out what they're saying, and I've seen fiery swords brandished by people trying to claim certain terms have one and only one meaning. Words and terms evolve and are often appropriated to multiple uses whether we like it or not. It can be confusing, but there's really no fighting it, just living with it.
