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?
 (O:)

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?
