Hey Paul,
most of the time, if you just need the hdr for lighting and blurry
reflections and you can be sure there won't be any crisp reflections
(glass, crome) in the render, there is no need to over complicate things.
I use an 180° fisheye lens on a regular tripod with a standard 3 way head.
I do1 exposure set every 120°(every leg of the tripod) and skip the top
and nadi shot for outdoors and just use the stamp brush in photoshop to
clean out black or wrong spots.
this gives you the correct lighting and something thats reflecting the
correct colors.
For this you don't even need a camera with a big sensor, just a camera
that does proper bracketing.
If you have reflective objects that need clear and crisp reflections
thats NOT the way to go, then you need to do It properly and the hdr
labs link is a good resource.
for stitching i would use ptgui, as most of the time It's just one click
and finish. I think hugin ist free and almost the same, but not as
comfortable as ptgui. At least when I was trying it about 2 years back.
hope that helps

if there is time and a budget for capturing set data, reference and
spherical HDRIs... then do it! saves time on the backend when doing
lighting. removes any guesswork from just having a plate.
i think the hdr labs forum is a great place to also ask questions

Hey guys,
I am helping out on a documentary that's being shot in China & the
subject of shooting spherical panoramas came up. For what these
guys are doing, I don't really think there's a need to shoot
HDRI's, but I do think having panoramas would come in handy.
The problem is, I'm being peppered with questions by the DP about
the subject (things like, "this requires a nodal head, right?")
and honestly I've never shot a single panorama in my life. I
think the DP is way overcomplicating & overthinking things, but
since I have no experience I don't want to give him bad advice or
information.
I sent him a link to the sIBL tutorial page (
http://www.hdrlabs.com/tutorials/ ) and that just added to the
amount of questions I'm being hit with. So I was hoping someone
on the list might have some experience with this subject & could
share some info & advice.
Thanks,
Paul
