gimp doesn't recognize images with colorspace adobe rgb
Last modified: 2009-04-30 09:18:41 UTC
Hello, I switched my camera (Pentax K200D) to store the jpeg images in the colorspace "Adobe RGB". I have colormanagment enabled in gimp (rgp profile srgb) and the file-open-dialog modus to "ask". When i open a image in gimp and look under Image -> Image Properties, gimp says that the images has no color profile. Photoshop under win recognize the images correctly as adobe rgb and convert them. I have read through some forums: the color space adoboe rgb is correct saved as folowing (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 gimp doesn't recognize them as adobe rgb and display the images with wrong colors. It is right that no complete icc profile is stored in the images, but the link to adobe rgb is stored correct and gimp shoud recognize it and display it correct. 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 : .
