So I have completed a Rec709 calibration targeting 2.4 gamma (low lamp) I started by loading a 1D LUT with Large Greyscale into the Sony. Then I completed a Greyscale quick profile, and loaded a 1D LUT into the Lumagen. Followed by a 17x17x17 Display Characterisation, uploading just the 3D LUT into the same CMS0.
So I have got to grips with Lightspace and Lumagen - thanks for your patience while I got my head around all the interactions, between bad cables and my lack of experience.
I have a couple of things still to clarify...
1. If I create a CSV file, and extend the Large Greyscale - will this improve the Sony 1D LUT? What is the practical limit? Is there a limit within LightSpace?
2. What is the recommended Cube size for Characterisation of a display if LUT in the Lumagen is 9x9x9?
3. If I want to repeat but targeting Gamma 2.2, I assume I can reuse the previous Large Greyscale quick profile, target 2.2 in the Colourspace Converter and upload to a new slot in the Sony.
With that selected, I can then either do another display profile 17x17x17 (Sony
), and upload 1D and 3D together, or break them out separately like before.
4. Pros & Cons of splitting 1D and 3D out.? I guess any changes in 1D LUT will mean new Profiling of the display if separated ....so is less flexible. If kept together, I can just create different LUT from the one profile?
