ImageMagick 6.9.1-8 Q16 x86_64 2015-07-14

input:
http://alumni.media.mit.edu/~erikb/tmp/ ... front2.tif
output:
http://alumni.media.mit.edu/~erikb/tmp/rgb_exp/out2.png

When I run this:

Code: Select all

convert front2.tif -profile sRGB_IEC61966-2-1_black_scaled.icc out2.png

Code: Select all

convert: Incompatible type for "RichTIFFIPTC"; tag ignored. `TIFFFetchNormalTag' @ warning/tiff.c/TIFFWarnings/856.

The result is in garish colors I did not expect (or want). The same conversion within photoshop is what I expected, as seen here:
http://alumni.media.mit.edu/~erikb/tmp/ ... /pshop.png

What am I doing wrong with ImageMagick?

Your tiff file is CMYK, but has no CMYK profile. To convert to sRGB when there is not CMYK profile in the input, you need to supply a CMYK profile as well as the sRGB profile. The following works fine for me on IM 6.9.1.8 Q16 Mac OSX

Code: Select all

convert front2.tif \
-profile /Users/fred/images/profiles/USWebCoatedSwop.icc \
-profile /Users/fred/images/profiles/sRGB.icc \
front2.png
