Hi, Greetings to all in the mail list,

I have couple questions in the context of capturing HDR environment
map for image-based lighting, and would like to hear your feedbacks.

When capturing the HDR environment map for a scene with concentrated
light sources (say light bulb or the sun), is it correct that if the
pixel values of the light source are not saturated in the most
under-exposed bracket (but saturated throughout the rest of exposure
brackets), the full dynamic range of the light source is well
preserved?

If I have two, three, or more under-exposed brackets presenting
non-saturated pixels for the same concentrated light source, will the
resulting HDRI be more accurate in terms of representing the
illumination of the light source during IBL than the situation where
the non-saturated pixels of the light source only present in the most
under-exposed bracket?

Thanks,
Jason
