# Line 2728 | Line 2728 | C++ class, but may have its uses.
2728   Fixed a bug in BSDF sampling of sources pointed out by
2729   David Geisler-Moroder, which tended to overestimate specular
2730   contributions for some BSDFs.
2731 +
2732 + Added handling of hyperspectral pictures to pextrem, though
2733 + results are still reported in RGB.
2734 +
2735 + Added conversion of hyperspectral pictures to ra_xyze, although
2736 + it is even slower than rcomb for this process.  It is more
2737 + accurate than most of the other tools, at least.
2738 +
2739 + Added handling of hyperspectral images to normtiff, a little-used
2740 + but handy program for quickly tone-mapping pictures and TIFFs.
2741 +
2742 + Added conversion of hyperspectral pictures to ra_ps using
2743 + approximate color method.
