[Radiance-general] macbeth gamut and coordinates

[genevieve lucet]

I need to correct the color of mural painting photographs and I am 
trying to do it using macbethcal. I observe that several colors are out 
of gamut  (diagonal lines are visible). When I apply macbethcal to the 
image �macbeth_spec.pic� that is included with radiance,  the yellow 
square shows the same problem.
Is it only a display problem or does it involve the calculation of the 
colors?

The chart has rounded corner. This is why I would prefer to put the 
coordinates of the color squares instead of the coordinates of the 
chart. Does it matter?

This part is not a radiance problem but if somebody can help, .. I am 
looking for a software to correct the distortion of these images to 
obtain orthophotos of these paintings.
