PTGUI - anyone doing panos with HDR?

    I am just idly playing with PTgui's HDR function, and am a bit lost in
    some aspects. So I'm being lazy and hoping someone may have already
    done some work in this area and can give a few quick tips on how best to
    set it up.

    In particular, a couple of basic questions have arisen - the help file
    suggests that 3 sets of images are used - is that correct? It didn't
    complain, and seemed to give me a nice, not-unnatural-looking result
    using just *two* sets:
    however I will concede that this was not a challenging example and
    doesn't tell me much. The scene wasn't really pushing the limits anyway..

    But do I really need to take 3 sets? - I doubt I would encounter too
    many scenes requiring *that* much hdr help.. And how have you set up
    the 'Camera Response Curve' and 'Tone Mapping' dialogs, or did you just
    leave them as default?

    I should probably point out that I do NOT like images that look
    unnatural, which seems to apply to a lot of the HDR I've seen (although
    Fr McK seemed to have it working nicely - are you still around, Fr McK?

    I imagine that if I know what I'm doing I can probably use it a little
    more productively and have a bit of control over the result.. (O:

    Any hints greatly appreciated. And yes, I've looked at the Tutorial and
    a few webpages, but am not feeling much wiser - is it Friday?

    Yep, but it all seems a lot of trouble when two sets would probably do..

    Thanks for that, I'll check it out.

    Well that's really the point: it depends mostly on just HOW contrasty
    the scene is. Some people even use 4, 5, or more sets on VERY contrasty
    scenes - say, a dark, backlit foreground subject with a bright sunset
    behind, where you want to maintain the highly-saturated colors and still
    get detail in the subject.

    If two sets suffices for your shot, there's no reason to take more...
    sometimes the needs change.
