LightSpace CMS profiling

Hi,

The Lightspace Calibration guide reads: "for example, if the display 'should' match Rec709, select Rec709... This is not a requirement for profiling as LightSpace CMS profiling is totally separate from the target colour space"......When profile a device that does not involve a target gamut like Rec 709, what type of color gamut does LightSpace CMS feed to the display to generate a device profile?

This is more of a general question of all calibration software, including Xrite that uses 'patches' of varying sizes to determine display response within XYZ. Are these proprietary?

Thanks

Hi Paul,

I think you are confusing two different functions.

When profiling LightSpace is reading the display's capabilities, and needs to know nothing about the desired target. So it matters not what the display 'target' is, as it is not relevant.

With other calibration systems you do indeed have to set the desired target colour space before profiling as they need to know what is expected of the display in advance. That shows a poor calibration system...

The calibration patches are just patches of known digital colour values, not a fixed gamut or colour space.

After profiling, when you do set the desired target colour space, LightSpace will then calculate what each colour patch should read for that colour gamut, and compare to the reading it actually saw.

Does that help?
