I did not viewed it but was this _available_ in the net as hdr file and
accesible? Then Why you wasted about 1 MB of space in this server rather then
post a link to original image ? Have you permission from author to repost ? Is
it http://www.debevec.org/Probes/campus_probe.hdr ?

That's not really what i would call an hdr light probe, the same effect
can be achieved much easier by using a normal image map and placing a
bright sphere at the position of the sun. Usual light probes have a
dynamic range of several 1000-10000 and the high dynamic range is not
limited to the immediate vicinity of the sun.

Looks like an ok 360 image, but have you used it in a Povray image?

I think he is referring to his post in povray.general
about homemade HDR images. But haven't checked
either image.

Needs HDRView from http://www.debevec.org/FiatLux/hdrview/
But don't bother for a single image. Get it if you intend to use Mael's
mlpov.

The weekness of the light probs I have seen is that the light source is the
same level as all other white surfaces in the scene. The light sources
should be much brighter than any other white in the image. To make a high
color image all it takes is converting it to 16 bit and either bluring it or
shrinking it. It is the same tools for makes smooth 16bit heightfields. With
the light sources in the image scaled 10 or more times the image provides
real light. Any high res image can be used.
