Cobalt Repro is a linear profile. There has been an increased interest in using it as the first step in processing.

Tony Kuyper has a nice writeup about using linear profiles (and a repository of linear profiles):

The Linear Profile: A new beginning in Lightroom and Camera Raw

 

I didn't see the M10 listed on Tony's site...

So I just made one in case anyone wants it - standard adobe M10 profile with linear tone curve (sic)

I don't vouch for it being useful, just here it is!!

Thanks.

You could send an M10 file to Tony, then he will add it to the repository so that other can access it via his repository.

It would be interesting to see a comparison of this profile with Cobalt Repro. Anyone like to do that?

Maybe he’d like it. I’d guess he’d rather do it himself for continuity of process

To be honest, I’m not sure that me, Tony or anyone should be taking material copyrighed to adobe, modifying it and distributing it… I guess adobe kinda gives them away (you can use the dng converter to turn any file into dng then use dng profile editor to extract the adobe dcp) but when adobe gives it away, it’s not the same as someone else doing it

I don’t have the cobalt one to test with!

I know, but I was hoping someone else would. I'm not great with testing and a bit busy these days...

I had a quick play with the M10 linear profile.

sorry it's just screen grabs

So on your left you have a 100% SOOC DNG in LR with the adobe standard profile (which I never use, I prefer my own) on the right you have the adobe linear profile, which in case you haven't read the above is exactly the same as the adobe standard, but with a linear tone curve

Now on Tony's website

https://tonykuyper.wordpress.com/2021/07/23/the-linear-profile-a-new-beginning-in-light-room-and-camera-raw/

He suggests using the 'auto tone' in LR as a starting point

Now BOTH images have had 'auto tone' applied

I'm going to leave this here, because further edits on my part stop being a direct comparison between two profiles and start being a showcase for me editing images, which would be flattering if you wanted to see it 😅 but doesn't really test anything about the profiles other than how I've decided to edit them

However..

 

The 1:1 view really does highlight the effect on the colours that the linear (on the right) profile has. And I only took this about 18 hours ago, so I feel confident telling you that the left hand shot better reflects the colour of the blue boat

 

========================

Personally speaking,

Like always with these things, use it on enough images and sometimes it'll work great, sometimes it'll work terribly, sometimes somewhere in the middle...

Personally I don't think a linear profile will add a lot to my workflow, but if it helps anyone then help yourself to it (see post #94)

actually I just put the linear TC into one of my own profiles, and although it generates a bit more arsing about in post, it might be something worth using from time to time

Tony wrote in his post that anyone can send him raw files of cameras that are missing in the repository and he will add the appropriate profile to the repository. 

The profiles that you generate with the Adobe DNG Profile Editor are not copyrighted by Adobe. The idea of the Profile Editor is that people generate new profiles and share it or sell it. 

[Adam Bonn]

Fair point, but I think opening adobe’s profile (which includes the tag “copyright adobe”) and clicking the box ‘linear tone curve’ then exporting it as a new profile stretches creating a new profile a bit.

To create a profile, you open the camera's DNG file not Adobe's profile. You own the copyright of your own DNG files.

To convert an adobe dcp profile file to an adobe dcp linear profile file, you open an adobe profile file

when you open a dng file (say a shot of a cc passport) in adobe’s dng profile editor you’ll also need to use an adobe profile file (the one embedded in the dng), although leica of course do embed their own dcp file in their dngs, but that’s the exception not the rule (as few cameras natively shoot dng)

if you make a profile with (say) the CC software tool, then decide you wish to add HueSatDelta table(s) in the adobe profile editor, you’ll need to select that profile from the drop down menu

in short, adobe’s dng profile editor exists solely to edit dcp files into new dcp files and (unlike the CC software) it cannot create one from scratch only edit an existing one.

this tool edits the base profile it doesn't edit the dng nor does it create a profile from the dng. 

the base profile menu cannot be blank

the base profile is the adobe one (or if your camera shoots dng it'll be a choice between the adobe one or the oem one)

You don't need to edit or convert the Adobe Profile you can make a new Linier Profile from any DNG file.

Open the Adobe DNG Profile Editor and go to File and open a DNG file for the chosen camera,

Select Tone Curve from the tabs in the window where it says Untitled Recipe,  often this can be a little difficult to see on some monitors but is the one next to the one that opens by default.  In the Base Tone Curve dropdown select Linear.

Go back to the File Menu and select Export Digital Camera Profile at the bottom.  This opens a save dialogue box.  The save name should be highlighted with the camera name and the save location already selected to place the file in appropriate place for Lightroom to automatically find it.  You can change the hightlighted name if you wish, I usually change it to camera name followed by Linear Profile.  Make sure you don't change the file extension from .dcp

Job done.

When you next use Lightroom to edit an image from that particular camera you should be able to select this new linear profile in the Profile dropdown of the Basic Panal.

This only works for DNG files so to make use of it for other RAW types you would first need to convert them all to DNG.

Hi Bob

As my screen shot above shows, you have to have a profile associated with the DNG image in order to edit and export anything

You can however open just a profile (not a dng) and do the same thing.

In short:

in DNG profile editor the base profile is mandatory the DNG is optional

 

[Adam Bonn]

Of course if you wanna be all down with the kidz and koolio and the gang...

Screw using dng profile editor.. Just convert your dcp file to xml using dcptool and add this

  <ToneCurve Size="2">
    <Element N="0" h="0.000000" v="0.000000"/>
    <Element N="1" h="1.000000" v="1.000000"/>
  </ToneCurve>

in the relevant section

or if working in json is more your bag, then dcamprof your bad boy and add

  "ProfileToneCurve": [
    [ 0.000000, 0.000000 ],
    [ 1.000000, 1.000000 ]
  ]

Hmm yeah but..

Anyway ok

Could I please trouble you to change the title to something like

Here's a linear tone curve version of the M10 adobe standard profile

Because 

"Making my own camera profile"

Implies I made something, when in actual fact all I did was add about 4 words and some numbers to the 70,223 words that adobe already provided in their standard profile.

Thanks in advance

That's correct and thanks for pointing it out.

However to choose a base prifile (other than from a DNG image) you have to know where Lightroom stores its Camara Profiles or you have to make your own from a DNG image, because as far as I know to make your .dcp file you need to use a DNG file. 

This will however, also have associated with it the embedded profiles chosen by the Camera Manufacture as the DNGs you use to create the colour checker profile will already have these embeded in it, so you are still using a DNG.  However for those less computer literate or who do not have the ability to make there own .dcp files then if you open a DNG from the camera you are creating a Linear Profile for it will list the profiles already associated with the DNG.  You can then choose which of these to use as your Base Profile before switching to the Tone Curve tab and selecting Linear.  If you look at the image window of the DNG you will see the results of the changes you have selected.  As such you could work your way through all of the embeded profiles and decide which you believe gives you the results you want for your new Linear Profile.
