How user can speed up complicated sky_sphere?

I was thinking of rendering scene with only sky_skyspere (and/or other 
elements so far that they can be considered as background) and then using 
sky_sphere with image_map.

What camera type ue when pre-computing, and what mapping use when fast 
rendering later?

Btw is it possible to create own .hdr from POV simmilar method as above 
(without using external programs)?

How about adding HDR support into Pov 3.6 - it's so usable option, any 
chances for that?

Good thinking.

Spherical camera, spherical mapping. Note that they work slightly
differently so if you want it to match up exactly, you'll have to do some
rotating and negative scaling of the image map.

IME, this will suit for test renders, but for high-quality renders 
you'll need a very hi-res image_map to avoid blurring and/or pixellation.

Still, if you've got a really complex sky_sphere, it MIGHT be worth it.
