I don't even own a grey card. ;) > And, if geeqie would use the internal preview 1:1 zoom levels wouldn't > be possible I guess. So it must be better at interpreting the WB in some > way. Or are the .CR2 included previews the full image size? I don't know about the other programs, but geeqie definitely uses the embedded preview. Darktable says the image is 5198x3462. Here are the embedded previews: exiv2 -p p raw.CR2 Preview 1: image/jpeg, 160x120 pixels, 13152 bytes Preview 2: image/tiff, 668x432 pixels, 1731456 bytes Preview 3: image/jpeg, 5184x3456 pixels, 2326610 bytes You'll notice that darktable gives you a few extra pixels, this is because the developers decided to give you all of the available pixels from the sensor, rather than the "official" number. Now, let's extract the JPG preview: exiv2 -e p3 raw.CR2 And compare them visually in geeqie: Original: https://www.dropbox.com/s/cext1wu7qj2ibrl/raw.CR2%20-%20Geeqie_094.png?dl=0 Preview: https://www.dropbox.com/s/ucfr8lz73c9p0on/raw-preview3.jpg%20-%20Geeqie_093.png?dl=0 Look the same to me!
