Thanks for the help guys, you've given me lots to think about. Getting
lcms to do the XYZ to Lab conversion seems like a good starting point.

Ian,
what is your Shake LUT about? RGB->RGB or Lab->Lab ...
One possible route:
Figure out what are the movements in your Shake LUT, bring it in relation
to a PCS colour space (LAB or XYZ), if needed, and use a profiling package
to interpolate the scattered data.
This seems a robust route to m

Hi,
I am trying to build a profile that I can use in photoshop to imitate a
LUT that I use in Shake. I use the forward sampler to go from RGB to
LAB, converting each RGB sample by calling a function to apply the lut
to that value then converting to LAB. The code looks something like this:
int
