It happens that the ICC encoding and the TIFF encoding are sligtly different: For decoding TIFF: -------------------- L: divide L by 2.55 a, b: substract 256 if greater that 127 For decoding ICC: ------------------- L: divide L by 2.55 a, b: substract 128 The http://www.littlecms.com/tiff8adobe.zip profile is doing the translation. Otherwise it doesn't touch any color.
