Some of my photos look different because I was not careful with saving with or without color profile. Now I would like to be able to find out what color profile is used by an image. Is there a simple tool to see this? Hopefully a command line one? I'll try to pay attention next time!
You can use imagemagick's
identify program for this.
$ identify -verbose example.jpg | grep -A1 Profile-icc Profile-icc: 560 bytes Adobe RGB (1998)
(I could not get this out with the
exiv2 tool mentioned in another answer.)
Have you got Adobe Bridge or Lightroom? Bridge can sort by Colour Profile, but I cannot find a way to do it in Lightroom, though it must exist (if it does in Bridge). This will only work in Windows or on a Mac though.
Alternatively, in Windows the colour profile is reported as part of the image properties, so it would just be an entry in metadata. So I would guess it should not be difficult to write a script that queries the metadata for every image, but I am the wrong person to tell you how to do that.
