= Steps to reproduce = * Process RAW image with Ufraw; export as 16-bit TIFF. * Import image into Krita. = Observed result = * Image looks too bright. = Expected result = * Image looks normal. This is confirmed in Gimp (git version), Dolphin's preview, and Gwenview. * See screenshot showing Gimp on the left and Krita on the right. As you can see, the histograms look consistent between the two. http://i.imgur.com/HsqDcUG.png * In addition, exporting from Ufraw into 8-bit, then viewing this file in Krita works fine.

Hm, no... I was wrong. That image doesn't contain a gamma tag. No idea where imagemagick gets it from then.
Git commit 33ea3d9259fb3ca1345ca2d5efeee788889b9a16 by Boudewijn Rempt. Committed on 24/01/2017 at 09:23. Pushed by rempt into branch 'master'. Related: bug 16 Assume that 16 bit rgb tiff files without a profile are gamma corrected. It would be better for people not to generate these files, or if they did, add the TIFFTAG_DCSGAMMA tag to specify the gamma, but that's unlikely to happen.
