Keep Absolute measurements?

[Roger Breton]

I noticed in the *.ti3 file the lines :

> LUMINANCE_XYZ_CDM2 “83.165805 87.953641 72.521981”
> NORMALIZED_TO_Y_100 “YES”

Is there a way to keep the measurements “absolute”?

I reviewed dispcal menus and dispread documentation for a flag of some sort, to avoid converting all measurements to “Relative” / Normalized to 100 but there is nothing I could find?

I know I can always massage the data back to “absolute” …

Graeme responded :

The -w flag disables the normalisation of the white patch value to 100.0, resulting in values that are in cd/m^2. This is mainly for diagnostic purposes. By default dispread will add a white patch if the .ti1 file doesn’t contain one, so that the .ti3 values can be normalized to 100.0, but this is not done if the -w flag is used. If -w is used and the .ti1 file doesn’t contain a white patch, then the brightness of the display will not be recorded in the resulting .ti3 file (LUMINANCE_XYZ_CDM2).

Is there a way to access this flag from within dispCAL?

Thank you!!!! Not that I would not be able to fire dispread directly but I appreciate the integration offered by dispCAL…

I owe you a beer 🙂
