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?
