Hi, I'm experimenting with the new "reconstruct color" mode for the "highlight recovery" module. On some pictures, it creates strange artefacts outside the overexposed parts.
See for example this image: http://www-verimag.imag.fr/~moy/tmp/highlight/reconstruct-color.png The bottom uses the default highlight reconstruction, and the top uses the "reconstruct color". The whole image has -2 exposure. On the top left, the gradient of light blue is turned into a uniform dark blue, so it actually lost details outside the highlight area. Then, there are kinds of horizontal hatching and weird vertical lines. The DNG and .xmp files are here: http://www-verimag.imag.fr/~moy/tmp/highlight/DSC_3749.dng.xmp http://www-verimag.imag.fr/~moy/tmp/highlight/DSC_3749.dng Surprisingly, the exported JPEG has less artefacts than the on-screen version: http://www-verimag.imag.fr/~moy/tmp/highlight/DSC_3749_v0001.jpg Any idea what's going on? Shall I turn this mail into a bug report?
