Version: 0.10.0-3 (using KDE 4.2.2) OS: Linux Installed from: SuSE RPMs Hello, I switched my camera (Pentax K200D) to store the jpeg images in the colorspace "Adobe RGB". In the color tab in digikam 0.10 there is no color profile listed for this images. For my ohter image, taken before the color space switching, there is the color profile srgb listed. Also the editor says, that the images have no color profile assigned and if i would like to convert them. I have read through some forums: the color space adoboe rgb is correct saved as foloowing (exif data): -ColorSpace=Uncalibrated -InteropIndex=R03 -WhitePoint="0.313 0.329" -PrimaryChromaticities="0.64 0.33 0.21 0.71 0.15 0.06" -YCbCrCoefficients="0.299 0.587 0.114" -Gamma=2.2 see http://forum.penum.de/showthread.php?id=52744 (german) or http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/EXIF.html These data is correct stored in my images (see below) but digikam doesn't recognize them as adobe rgb and display the images with wrong colors. Digikam should recognize the images as adobe rgb as photoshop under win does. gimp under linux and win are also failing. Colormanagment in digikam is switched on and workspace profile is srgb. Here is the exif data read with exiftool from one of the images: ExifTool Version Number : 7.42 File Name : eis_2009.01.06_17-52-28-002883.jpg Directory : .

This is relevant of Exiv2 library in first. Which Exiv2 release you use ? Please give us an image sample to test. Gilles Caulier

Is reading the "R03" tag and using AdobeRGB(1998) sufficient or do we have to check the whitepoint, gamma and primary chromaticity?
