By contrast, if I load a JPEG file from the camera into GIMP, both tags are set to sRGB and there is no problem with thumbnails. This is obviously unsatisfactory in itself, but owing to the tag remaining as Uncalibrated, I cannot be sure the image has the sRGB profile embedded. Darktable est un logiciel de retouche photo non destructif spécialisé dans le traitement des fichiers raw. Curiously, this does not change either of the two ColorSpace tags above. I have found the only way to show the thumbnail correctly in Gwenview is to reload the JPEG into GIMP, ensuring that the option to promote imported images to floating point precision is unchecked, specifically assign the GIMP built-in sRGB profile, then re-export as a JPEG.
DARKTABLE 2.4.4 CODE
If I will have more time, I will finally get the Code and hopefully provide a fix. To add to the doubt, the Gwenview image viewer, while it shows the full-sized image correctly, displays the thumbnails much too dark. darktable darktable es un programa de procesamiento fotogrfico en formato raw ( negativo digital, es decir, imagen sin pretratar por la cmara) de cdigo abierto. More annoying bug is snapshots, that works bad after rescaling window. I have been advised that some images that I sent out as JPEG files did not contain an embedded profile, although GIMP's Image Properties insist that they have the GIMP built-in sRGB. The Colorspace information for the image that Darktable exports shows up in Image -> Metadata -> View Metadata as: Darktable is a virtual light-table and darkroom for photographers: it manages your digital negatives in a database and lets you view them through a zoom-able light-table.
In my case my starting point is Nikon NEF files. Darktable is een virtuele lichtbak en donkere kamer voor fotobewerking. Darktable will be the default theme in Darktable 3.0, but users will also be able to use alternatives like the Darktable Elegant Dark, a lighter version of the theme, and Darktable Elegant Darker, which has more condensed fonts best used with the Roboto font, according to the developers. In most cases the desired final output from GIMP is a JPEG with sRGB profile but I can find no settings which give me confidence that this is working properly. Darktable heeft versie 2.4.4 van het gelijknamige opensource-raw-fotobewerkingsprogramma uitgebracht. This is logical since it is desirable to work with floating point precision in GIMP 2.10. When using GIMP's Darktable plugin, I think I am right in saying that that closing Darktable always imports the image into GIMP in the form of a floating point EXR file with profile linear Rec709 RGB. This issue refers to GIMP 2.10.8 and Darktable 2.4.4, running in Linux (KDE). I now believe this to be a GIMP issue, but I cannot be sure whether the behaviour described is effectively a bug in GIMP or whether I am missing something. I am new to this group, but was referred to it after posting a description of the problem below to the Darktable forum.
