As said → Add soft proofing to Photolab - #16 by sankos ( follow also further down)
→ Converting to ICC colour profile - #3 by wolf
during image export, DxO uses perceptual rendering intent and no black point compensation.
When colours outside of sRGB are detected (e.g. from wider AdobeRGB),
all colours are shifted/squeezed to fit in the smaller sRGB colour space,
while visually keeping their relation → “perceptual”.
The old LR 5.7 has a clever solution to visualize in Softproof mode
-
if the file’s colour space exceeds the monitor’s colour space ( → monitor choice )
(Melissa/ProPhoto RGB vs. AdobeRGB / sRGB) -
if the file’s colour space exceeds the print’s rendition ( → paper choice )
(with profil for my printer & matte paper / RI relative)
