Colour Management in PL6

This statement

triggered me to do experiments …


some comparisons
(w/ sRGB screen, PL6 WG)

.
1.


colour spaces of present & affordable monitors

  • black = AdobeRGB
    green = DCI-P3
    yellow = sRGB

.
2.


different coverage of sRGB (display profile & export to print service) and RGB paper profile

  • black = ProPhoto → here representing anything in Wide Gamut
  • green = RGB paper profile for a photobook by SaalDigital
  • yellow = sRGB

.
3.


the pic with DxO Standard preset

.
4.


same as 3., with Monitor gamut warning ON (blue overlay)
(shows the out-of-gamut area for the sRGB monitor)

.
5.


same as 4., but some saturation for green reduced
(reduced until the warning was almost off – and the pic in-gamut)

.
6.


same as 4., softproof to sRGB, with Destination gamut warning ON (red overlay)
(–> toggle between Monitor and Destination gamut warning – they cover the same area)

.
7.


same as 6., with some saturation for green reduced
(turns both warnings almost off)

.
8.


same as 4., softproof to paper profile, with Destination gamut warning ON (red overlay)
(–> toggle between Monitor and Destination gamut warning – the coverage differs !!)

  • more red overlay than in 6. = less colours than in sRGB
  • less red overlay than in 6. = more colours than in sRGB

.
9.


same as 8., with some saturation for green reduced

  • more red overlay than in 7. = less colours than in sRGB

.
general note

  • With softproof & export to sRGB IEC61996-2.1, DCI-P3 & AdobeRGB & ProPhotoRGB
    DxO uses its ‘automatic’ rendering (“PSCA” → the initial graphic).
    The visible rendering intent (perceptual / relative colorimetric) is not used.

  • With softproof & export to paper profiles DxO uses
    the rendering intent perceptual (by default) or relative colorimetric.
