Image formats for realistic rendering
It is remarkable to me that there is no accepted standard for high dynamic range images that is based on CIE standards. Such a format should support XYZ and scotopic luminance V. A big dump with four floats per pixel would work fine, although of course more compressed formats are certainly straightforward. If anyone is aware of such a format that programs such as photoshop can read out of the box, please let me know.

OpenEXR might do the job. There's a section in the "technical introduction" on how to use it to store pixels in XYZ.
Photoshop won't read it out of the box (yet), but they do offer Photoshop plugins for it.
Thanks I will check that out. A photoshop plugin could be sufficient. I am worried babout the V channel though...
