Excess of correction

Hello Steve,

I begin to master and to appreciate your HCL software.

However I meet one problem of calibration below 40 % in the sense that the correction is too strong so that the relationship

of the RVB is practically inverted compared with the initial state.

This is perfectly visible in the 'RGB Balance' window.

The scale of the grey is corrigeable via the Lumagen calibration Gamma function but it is not sufficient.
I imagine that the defect of correction persists in the cube so that by viewing a movie we have the impression that the male

actors wear a 3-day stubble (I would say nothing about the ladies).

I use for the measures a ColorMunki Photo reference probe, the measures of which put back in the file ' Reference

Probe/Display Presets ', those of the I1D3 are in that of ' Activate Probe / Display Data '.

This report was made as well on my JVC X3 as on the JVC X95 of a friend, The probe managed towards the screen or towards the

prokjector, in Hybrid Cube-13 or in Quick Profile measurements.

I use the mode Burst with 1.75s of time(weather) of integration, I also tried to rise in 3s without obtaining from better
results.

I do not think that it is connected to a problem of measures because the threshold adorned me too high at also because the

results are very close with those realized via HCFR.

There is doubtless something that I do wrong but I do not know what.

One can send files and images directly on the Forum either is it necessary to pass by email?

Sorry to say I cannot make any judgement based on the information you have posted.
It actually sounds like you have done something wrong, but I have no idea what...

Send me the profiles and the LUTs you have made to my e-mail address and I'll have a look.

You have inverted the profiles in 'Convert Colour Space'.

Steve, I am sorry.
I am afraid of having made you waste your time because I believe to have sent you bad files.
I effectively tested this option, but it was later.
I am thus going to redo these measures for sent you the right files.
