ColourSpace - Retrospective Probe Matching

With the new 'Retrospective Probe Matching' within ColourSpace, users need to change the way they think about probe matching, compared to alternative calibration systems.

For any probe matching process - used via Manual Measure, or with Profiling - the user needs to simply set the Probe Matching options within the Probe Options menu, and enable matching when required via Probe Matching Active within Graph Options.

Any probe readings, both live measurements and saved profiles, can therefore be displayed with or without probe matching applied, as desired.

Where it gets a bit more 'interesting', is when a profile is saved into the library, as the status of Probe Matching Active is applied to the saved profile.

It is therefore recommended to use a profile name that states if Probe Matching was active, or not, when the profile was saved, to prevent double application of Probe Matching.

If Probe Matching is being used to correct a tristimulus for the given display being calibrated, the profile MUST be saved with Probe Matching Active for use with later LUT Generation.

Obviously, a profile can initially be saved without a Probe Match burnt-in, as it can be opened at any later time, have the Probe Match applied, and re-saved with the probe match burnt-in.

It is just key to know that probe match has been burnt-in to any profiles that will later be used to generate calibration LUTs.

Hi Steve,

Once probe matching is burnt in, is there any way to apply a different reference later? For example, lets say I correct a Klein K10 with a Jeti Specbos and save the profile with probe matching active. So the probe matching with the Specbos is now burnt in to that profile. Later, I decide that I want to now apply a CR-250 as the reference to this same profile. Is that possible? Seems that maybe we should save without probe matching active if we think we may ever need that flexibility.

If probe matching is burnt-in, it is burnt-in.
You cannot later 'undo' that.
That is why you can save with/without, as needed.
