DPP4 Adobe RGB processed incorrect

[Skies]

I upraded from DPP3 to DPP4. (4.6.10.0)

I was stuggling with the shadow areas of the photo's I processed.

There was no detail in the shadows, it was pure black.

Today I opened an old image and exported it with the same settings, and discovered that DPP4 is displaying AND EXPORTING Adobe RGB all wrong. It's a mess! 

When changing to sRGB colors are ok, but when choosing any other profile the contrast increases, like the top and bottom of the spectrum are cut off. But it should not change at all!! Just like when converting to another profile in Photoshop.

Am I missing something here or what the..?

Attached are two screenshots of the DPP2/3 (top) and the DPP4 (bottom) version, as seen in Photoshop.

Note how the DPP4 version has lost all detail in the shadow areas.

Settings where the same for both exports. (defaults)

Also note the histogram that also shows that the actual file is different and it is not my color settings.

So I guess it's back to DPP3 again until this incredible bug - that for some mysterious reason has not been mentioned anywhere before - is fixed.

Sorry for my frustration but I recently also was blown away by a totally messed up 'saturation' slider on the Adobe side, that also nobody seemed to notice (Lumetri saturation in Premiere Pro). Adobe raw colors are also horrible and that's I why I use DPP.

I hope I am missing out on some checkbox or something that solves the problem.

So I rarely use the Color Adjustment tab in DPP.

In DPP 4.9.20.0, when changing any color in the tab to any value (0.1 for example) the black values return normal!

The best way to demonstrate is via this video:

Hi Skies,
Finally I found someone who notice the same bug!

I also noticed in DDP4 (v.4.12.20.03, Mac OSX) that SRGB color tend to green/yellow what a i don't like, but still I see more information on whites and blacks than in adobeRGB.

I use a canon 6D.

So finally, the best workaround would be changing any color value (0.1 for example) and then make other adjustments?

Yes, that's what I have been doing.

But Ive since switched to DxO Photolab, which, with the right camera/film profiles can produce very impressive results. Some photo's still look better in DPP though 😉

I also still use DPP for viewing and selecting since Photolab isn't exacly fast in that regard.

I have Digital Photo Professional v4.20.20.0, and the described problem still exists. I am using the Canon EOS R5. Thanks for sharing the workaround.
