    Perspective is simply the relationship of objects closer and farther
    You are refering to linear perspective here. And, there is more to it than
    simply judging the size of objects.By your criteria, size is the only
    indicator of distance, but what about atmospheric defraction, dispertion of
    reflected light, overlapping objects, etc. If all we do is look at relative
    size and then judge perspective, we wouldn't be able to come up with a shot
    where two objects that look the same in the final print were actually at
    different distances in the original scene. Your criteria for judging
    perspective is too strict.

    If we arbitrarily start with the axiom that perspective is simply the visual
    affect of receding distance, then it would be hard to describe the effect
    produced by capturing an identical scene with differing focal lengths. In
    my opinion, one can only describe it in terms of perspective. "Distortion"
    just doesn't work because the lens is not distorting the scene, it is simply
    capturing it from a distinct rectilinear perspective.

    Now, to mess with your mind just a bit more, what would you say, John,

    See if anyone can use these (pretty much) identical clunky push-button
    panorama scenes, with differing focal lengths (17mm, 24mm, 40mm) as
    the only variable, to explain what perspective /is/:

    I think there are enough meanings of perspective that each should have
    a new term to designate that instance in that context, something like
    "bokeh" has been adapted and adopted to describe something a number of
    previously vague or esoteric terms attempted to do for what is a real
    effect.

    If we choose to stict with the perspective equals distance formula, what
    term do we use to describe this affect? Angular Compression? Focal-length
    Variance? I doubt these terms will catch on... They just don't do the job.

    And, what would happen if we through in 100mm, 200mm and 300mm as further
    test shots?

    It seems that we already do have some differing terms, such as rectilinear
    perspective, linear perspective, fish-eye perspectiveand panorama
    perspective, but people aren't using them, nor taking the time to understand
    the difference.

    Do we have enough terms to cover the multitude of rhetorical permutations?
    I doubt it. But, at least, we can start by trying to sort out the
    differences in the terms we have, and then see if we need more.

    What do you think?

    Go back to the message I originally replied to understand what we're talking
    about.
    I still win 'cos what you're talking about is irrelevant. :)

    Another net cop trying to control the agenda eh?
    Maybe you could go back to MY reply to understand what I was talking about.
    According to you. If that's all your on about, good, luck to you!
    BTW tell us what your prize was?

    Wow! Good on you for owning up to it. That takes courage and humility - well
    done! :)
    No, I don't think I need to revise, thanks.
    I guess you mean "you're". The prize is outsmarting a fool, but it's a very
    small prize. :)

    It's been fun T, but I need to leave you alone now. See ya 'round.

    I see you failed reading and comprehension at school, you have my sympathy.
    Small things, small minds and all that! Good riddance.
    I hope not.
