GIMP export to sRGB doesn’t match up to the original colorspace. https://photos.app.goo.gl/H88CHi9JyD94n6yT9 Here’s a wedding bouquet, in three images. Only the JPG straight from the RAW processor (I use ASP3) matches the image correctly.
My normal workflow is (1) processing RAW in ASP3, (2) export to TIFF ProPhotoRGB, (3) make last minute edits in GIMP, (4) print from GIMP using TurboPrint (Canon Pro100 or Epson P800). Works great. All the color profiles match up perfectly from a color registered monitor to the final print.
If I replace step (4) with export into JPG from GIMP, the colors shift. I’ve given a link above to three flower images, and only the one that isn’t touched by GIMP is correct.
My workstation is Ubuntu 16.04, GIMP is 2.9.9
Any ideas would be appreciated
UPDATE: Following the suggestions of respondents, I’ve updated to 18.04 and am running 2.10.x. The bug was reported as resolved, and, sure enough, everything is good.
