[Lcms-user] Color space conversion

[Andreas Y. <an...@ya...>]

I use ImageMagick (convert, specifically) to create JPEGs for the web  
from PSD files. This worked without a hitch when the files came from  
an inexpensive digital camera that saved everything in the sRBG color  
space. I've since switched to a DSLR and am experimenting with Adobe  
Lightroom, which operates in the ProPhoto RGB color space.  
ImageMagick does not appear to understand the embedded color space  
information, and the resulting images look very flat when displayed  
on the Web.

I'd appreciate any suggestions on using Little CMS to perform  
perceptual mapping between ProPhoto RGB and sRBG when creating the  
JPEGs.

My workflow involves a Lisp program that batch converts directories  
of PSD files into JPEGs for display on the web and writes the HTML  
code to tie everything together. This program calls convert and  
identify for image processing operations. It would be handy if I  
could determine whether the original image is stored in sRGB or  
ProPhoto RGB, since I'll have a mix of both.

Thanks,

Andreas
