Thanks for your reply Graeme,
Lots of reading material there I will go through it in detail over the next few
I understand that Lumagen is not directly supported, however, I'm happy to
share my simple scripts which could possibly help to add that support in future.
My current plan is for the following procedure; perhaps you could let me know
if this is reasonable:
Check white point 100% and/or 75%. Manually adjust RGB drive levels in
Panasonic service menu to achieve correct white point and desired light output.
Create patch set for 21 point grayscale.
Measure grayscale response - calculate correction values - upload these values
into the Lumagen grayscale table.
Profile using the 21 point grayscale and if necessary itterate correction
values until the desired output is produced.
Create 125 point colour patch set 5x5x5 3d LUT. Measure response - calculate
corrrection values - upload these values into the Lumagen colour gamut table.
Perform full profile - itterate entire process if needed.
At the moment I'm still not clear that ArgyllCMS can do the grayscale part. And
I'm not sure if it makes sense to apply the 3d LUT over the top of the
grayscale correction. Ideally I want to use both the 21 point grayscale and the
125 point 3d LUT in order to get the most control (5x5x5 points on their own is
not very high resolution). I have now bought an i1 display pro which hopefully
should speed up the whole process.

My main question is... can I get ArgyllCMS to generate the grayscale

I'm new to all of this so any advice would be great. At the moment I'm not
sure if I
should be using relative calorimetric or perceptual etc. I'm guessing I
aiming for rec 709? I would probably like to configure a couple of different
