IM Colorspace different from Photoshop

Post by eafalcao »

Hi all...

I have this image http://dl.dropbox.com/u/40859709/Adobe_ ... C1_7_.tiff

When I see it in Photoshop, says that is RGB Colorspace.
However in IM, I've got sRGB:

Code: Select all

identify Adobe_RGB_07300029030013_A2C1_7_.tiff 

TIFF 2513x3463 2513x3463+0+0 8-bit sRGB 14.18MB 0.000u 0:00.006
identify.exe: Incompatible type for "RichTIFFIPTC"; tag ignored. `TIFFFetchNormalTag' @ warning/tiff.c/TIFFWarnings/821.
identify.exe: Unknown field with tag 34864 (0x8830) encountered. `TIFFReadCustomDirectory' @ warning/tiff.c/TIFFWarnings/821.
identify.exe: Unknown field with tag 42033 (0xa431) encountered. `TIFFReadCustomDirectory' @ warning/tiff.c/TIFFWarnings/821.
identify.exe: Unknown field with tag 42034 (0xa432) encountered. `TIFFReadCustomDirectory' @ warning/tiff.c/TIFFWarnings/821.
identify.exe: Unknown field with tag 42036 (0xa434) encountered. `TIFFReadCustomDirectory' @ warning/tiff.c/TIFFWarnings/821.
identify.exe: Incompatible type for "RichTIFFIPTC"; tag ignored. `TIFFFetchNormalTag' @ warning/tiff.c/TIFFWarnings/821.
Anyone knows why?
Thanks!!

Does it look different in PS and IM? If so, perhaps post a link to your image.

Since IM 6.7.6.7, IM switched the meaning of RGB and sRGB, so that those colorspaces properly corresponded to linear and non-linear colors, respectively.
