I would like to know just what everyone conciders HDR here too. I work in CG graphics, and HDRI means something else to me... High Dynamic Range Image. We use photos that have a greater range of lights and darks than can be shown on a picture, ie the light areas in a HDR image are actually used to emit light to the environment and the dark areas are not lit untill their light value lower than the divice range is filled, thus it can be used to light a virtual scene. If you are making a picture that will be viewed on a screen or a bit of paper you are limited to the divice dynamics, ie pure white is only pure white and can not emit light or be brighter than white, in the same way black is only ever black. So i would have thought that a HDR image on screen is not really a HDR image but a CDR, compressed dynamic range, something like A Adams zone ranges. I would also be interested to hear what settings people use in their layers for these cHDR images?
