5DS(r) tone curve in LR and ACR : crushed shadows with all profiles

[MayaTlab]

Hi,

When Adobe released LR CC with what appeared at the time as a preliminary handling of the Canon 5DS(r) files, I noticed that the tone curve with all profiles (either Adobe standard or brand-specific profiles) seemed to produce much darker shadows than all other Canon cameras. This is something DPreview's noticed too :

"Furthermore, comparisons are slightly complicated by the aggressive tone curve ACR is applying to the 5DS R files that are crushing its blacks, and potentially decreasing the levels of visible noise by making them darker. We expect a later version of ACR to fix this, at which point we will re-process and revisit these results."

With the release of LR 2015.1, I was expecting this behaviour to be corrected, but that isn't the case. Is it something that's inherent to the 5DS(r) files ? Does Adobe plan to correct this ?

Thanks

MadManChan2000 Thanks for your reply ...

Not sure why my DPP4 was set at -4 but i think it was the first time i ever used it. Good to know you think this may be the issue.

Any chance Adobe can update the profile or offer it as default / standard because the existing profile is killing the camera out the bag in ACR.

Hi Rod,

Earlier in this thread, I posted two links to variations of the color profiles (one for the 5DS, and another for the 5DS R) where the contrast is lower and is probably a closer match to the DPP -4 setting.  I called these "Medium Contrast" versions.  Please give these a try and see what you think.

Cheers,

Eric

MadManChan2000 Yes, i have installed the medium contrast profile Eric - It's much better than the Adobe Standard default.

I think everyone would agree it should be default as much better to start of soft and increase contrast to taste.

Appreciate all your assistance.

This is an old thread, but I wonder if the reason DPP is showing a Contrast -4 for one person and 0 for others is that DPP is picking up the camera settings, and the CAMERA is set to Contrast -4 for the one user.

Hello,

I was reading all of this thread... Some interesting informations that helped me to tweak my own profiles for my 5DS and my 5DSR.
Here are my profiles :

There are 8 profiles :

The difference with or without the offset is the offset of the light. With offset profiles, pictures are more lighten (test them and look at the histogram).

The author of "medium contrast" had taken the 6D curve and applied the "adobe standard" colors. For my self, i had used for a while a 5DMarkIII and i had taken the curve of this one for the new profiles. And, for the colors, i had taken the original colors from the "Camera Standard". And, i did it for the "Neutral" profile too, because sometimes, i like to use this one.

So, the difference with the adobe profiles (neutral and standard) and my profiles, are only the Base Tone Curve (as you can see in DNG editor), and for the offset profile, an offset more lighten. They all share the same base colors : the adobe colors (that matches, unfortunately the Canon from DPP).

New Profiles for both 5DS and 5DSR you can see in camera raw :

Base Tone Curve from "Camera Standard" with adobe profile (strong shadows) :

Base Tone Curve from "Camera Standard - Normal Base Tone Curve" (and 5DMarkIII Base Tone Curve) :

Well, hope these profiles will help someone

now that Lightroom 6.8 has 5DSR profiles incorporated  does anyone know if they are exactly the same as the workaround profiles we had of yore?

Hi from 2021, bro. You cried about tone curve in 5ds, so how you like new tone curves in new cameras? lol... Its just a hell... Adobe stop please. NOTICED - All nikon cameras have normal curves. (exam D850) Сorporate conspiracy?
