I am experimenting with generating lookup table based ICC profiles.
I know it is a difficult task but I want to generate simple lookup tables.
I have the following queries regarding this.
1- What is the purpose of input and output curves in AToB0 and AToB1 Tags
(lut16type)?
2- Are the input curves used for gray balancing ? Can you devise how can I
experiment for this purpose.
3- I generated CLUT for AToB1 by measurements, chromatic adaption to D50,
normalizing and converting to fixed point.
How can I generate similar for BToA1 (the reverse, XYZ to RGB) ? I think it
is not simple inverse.
4- How is the TRC related to input curves in AToBx ? And how is TRC generated
from measurement data ?
Thanks for your help.
