I hadn't realized @flhoech implemented the CIECAM02 switches in dispcalGUI but it would probably be better if he gave an example since I've only used the command line version. I'm interested in what the smoothing checkbox is doing.

Just a heads up though if you do use this model is that your measurements will no longer line up with Rec709 standards because the model is attempting to match display appearance based on perceptual changes due to environmental conditions.

Disable "Enhance effective resolution..." and both "Gamut mapping for...", then enable "Low quality PCS-to-device tables" (this is universally applicable when the profile should be used to create a 3D LUT). Set profile type to "XYZ LUT + swapped matrix".

The CIECAM02 options are currently only implemented for "normal" display profiles (where the PCS-to-device table is actually used), it won't do anything when the profile is used to create a 3D LUT because the way I'm using collink in dispcalGUI ignores the PCS-to-device tables and inverts the device-to-PCS tables (collink -G). You could specify CIECAM02 options for a 3D LUT via "Set additional commandline arguments" in the "Options" menu though.

It applies a very basic linear interpolation filter over the generated colorimetric PCS-to-device table values.

Could you explain the difference between this ^^^ and the standard XYZ + Matrix, I presume you are recommending swapped matrix because ss is profiling a Plasma display?


Has anyone played with the DR Emphasis as the default is 20%, is this more geared toward LCD/displays with a higher Mll, if using plasma with a very low mll would it be wise to try 10% or even 0% when targeting a Plaw gamma.

There's no point computing an accurate matrix (+ curves) when the profile is (only) going to be used to create a 3D LUT. The only profile element that's relevant in the 3D LUT case is the device-to-PCS table.
If you're going to use the profile in other ways (e.g. installing it so it can be used by ICC color managed applications), then yes, it's important that accurate PCS-to-device tables exist, and may make sense that accurate matrix + curves exist aswell so that applications with flaky ICC color management support can atleast fall back to that in case they can't use the tables.

Thanks F, makes sense.


I've been using XYZ +accurate matrix as per the original workflow (Post 2) but will now use swapped matrix as per your suggestion, thanks!

Is there a new snapshot beta of Argyll CMS for dispcalGUI 2.6????

The last 1.7 beta I have for ArgyllCMS is from May 21st.

Thanks.

Nothing of significance. With the help of some others, I've been working on a new feature, but it isn't finished yet. When it's done, I'll do a V1.7 release.

You posted on Freelist a V1.7 update dated 12/10
Is this a copy and paste update like the beta from May.?
Also a dev_src, Zip. Should this also be installed. ??

Thanks,

ss

It's an update to address a serious problem with illumread. Unless you are profiling printers using FWA (Fluorescent Whitener Additive) compensation, I doubt it's of any interest.

Only if you normally compile from the source, and wish to get the fixed illumread.

Is is currently possible to import a custom patch set into Argyll/DispCal, like a .csv file etc ?

If so, can you elaborate on the requirements of the syntax and file structure ?


Thanks.

The testchart editor of dispcalGUI will have CSV im- and export capability in the next version (drag & drop a CSV file to import, click "Export" and choose CSV format to export). This is already in the latest development snapshot (currently 2.6.0.3), available via 0install or standalone.
