Be careful: 2.1 is the development version, the latest stable is 2.0.1. Reporting bugs on the development version is probably appreciated from the devs, but I don't think you want to use it in production. > Everything seem as nice as usual, except I have a problem with the > tone curve module : when I turn on the tone curve module, the colors > of the pictures are modified (even if, the module is set to what I > think is "no effect" - untouch diagonal curve).

See the gamut clip option of the input color profile: https://www.darktable.org/usermanual/ch03s04s03.html.php#input_color_profile It may or may not help, just a guess. -- Matthieu Moy http://www-verimag.imag.fr/~moy/ ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
