Thank you Steve.

Could you explain the new feature ? For example : what is the Differential Gamma graph ?

DifGamma is just a different way to show Gamma...
It is exactly the same data as the present Gamma graph, but shows the data 'Differentially',
The closer the plot is to a horizontal line the better.
Any points above the line will show as being 'lighter' than the target, (so a lower gamma value), while points below the line will be darker (so a higher gamma value).
The graph is this way around to match the existing gamma display, where the plot being higher than the target curve shows the image as being lighter - so a lower gamma value.

Very well, thank you Steve

Nice! Getting to know LightSpace over the last few months has been a joy - not only for profiling and building LUTs but it also makes a superb show'n'tell when customers don't really understand.
