Checking out the “New Features” in the 6.1 update …
Color Management specific;
-1. A new option has been added in the export dialog window to protect saturated colors (useful when exporting to a narrower color space)
… … If “ON” the result is equivalent to the on-screen PSA slider = 50.
Previously, the Protect Saturated Colors Algorithm was applied automatically (when Soft Proofing was activated and/or during the Export-to-Disk process) … This behaviour was catching-out unsuspecting users when they were not aware - particularly for images with saturated colors - that what they were seeing on-screen within-PL (without Soft Proofing activated) may not be the same as what they see when viewing the exported image on the same monitor.
Now, application of the Protect Saturated Colors Algorithm is a user-specified option - but only ON (for the same result as was previously automatically applied) or OFF … Which I don’t reckon is any improvement in behaviour at all … because, see the next point.
-2. A new slider to protect saturated colors has been added in Soft Proofing (This additional slider helps you protect saturated colors in Soft Proofing, when using a display ICC profile with a narrower color gamut.)
By default, the setting for this slider is “50” … which results in the same “strength” being applied to the instance of the Protect Saturated Colors Algorithm that we see on-screen within-PL as is applied during the Export-to-Disk process.
In other words, this is identical to the result that was previously applied automatically.
I have no idea why anyone would want/need to set this slider to anything other than the default setting of 50 … because that would not be reflected in the image exported to disk … because, with Protect Saturated Colors option in the Export dialogue = ON, the “strength” is fixed at 50.
I don’t see how this is supposed to make anything easier/more obvious for the unsuspecting user who is not aware of the importance of Soft Proofing even for the simple & typical case where one is working on an sRGB-limited monitor and exporting to disk for consumption on a monitor of that very same capability (?!)
