With PhotoLab, Rendering Intent applies to files exported for printing.
When the export target is a digital image file (ICC Profile = sRGB, Adobe RGB, etc) then the Rendering Intent selection in Soft Proofing is ignored.
- As noted above by Wolfgang, enabling of Rendering Intent when the ICC Profile is a digital image file is a mistake - aka a bug ! - - This was pointed out to DxO long ago, during PLv6 beta testing … but it’s another of those UI glitches that has never been fixed … Sigh !!
Instead, when the ICC Profile is a digital image file, PL applies its proprietary “Preserve Color Details” algorithm … For a LOT more info on the PCD algorithm, see here.
-
During beta testing, the PCD algorithm was described to us as “An algorithm developed by DxO. It’s neither the same as Perceptual or Relative Intent - it’s something in between”.
-
In my experience, the PCDA does an excellent job - and it saves us from having to make a choice between Relative and Perceptual Intent … as it’s a combination of both, tweaked for the specific requirements of each individual image
