Ciecam02 began to be implanted in RT in 2012 … with many problems related to the gamut of Ciecam
Since working on one hand on these limitations and on the other hand on an optimization, we have Ingo @heckflosse and me, made ciecam02 usable in a majority of cases
Last fall, @Elle Elle Stone , proposed to add the “symetric” mode which allows in particular to fully use the chromatic adaptation functions. I have create a branch “cat02wb” where this adaptation is used complementary to WB (whithout using GUI of Ciecam, and limited to cat02).
This adaptation has 2 interests:
1 - catching the errors of WB, because it is obvious that except for special case the WB is a kind of black box, where the real WB comes out of the riddle rather than science
2 - to use ciecam as it is intended, that is to say, to adapt the colors as do our eyes and our brain and not only in a Cartesian way, for example taking a picture in tungsten light (2856K) for example in a shop.
If you look the photo, and what your eyes seen, without Ciecam you will see a big differences, with Ciecam virtually no.
Of course, Ciecam is not limited to cat02…
One of the last limitations of ciecam02 is the nature of some illuminants.When the CRI is bad (less than 90 I think, for example Illuminants Fluorescent) the results will be bad, and I think there is no solution except not using these illuminants.
