where the dcp files related to Adobe Color?

[Chlheng]

Hello camera raw team.

I am glad to see that ACR 10.3 has a big update. It add a new profile called "Adobe Color". I can't find any dcp files related to it.

Can someone tell me the dcp file paths?

Best wishes!

"Adobe Color" is XMP "Enhanced" preset profile, it is not a genuine DCP camera profile... what it does - it references some external dcp camera profile by name for ACR to use and then ACR replaces the LookTable from that dcp camera profile with the one encoded in XMP preset profile (crs:Table_)... Adobe puts "Adobe Profile" as crs:CameraProfile="Adobe Standard" ... so you have Adobe Standard dcp profiles individually for each camera model (now that does not mean that they all different internally), but only one "Adobe Color" XMP preset profile is installed by Adobe...

on Windows Adobe installs those XMP presets profiles to the folder that you can find by going to any of the following locations (they are all in fact one folder) :

C:\ProgramData\Adobe\CameraRaw\Settings\Adobe\Profiles\Adobe Raw

C:\Users\All Users\Adobe\CameraRaw\Settings\Adobe\Profiles\Adobe Raw

C:\Documents and Settings\All Users\Adobe\CameraRaw\Settings\Adobe\Profiles\Adobe Raw

Minor clarification: the look table in the Adobe Raw profiles (such as Adobe Color) is not replacing the look table in the base DCP, but is applied after it.

thank you - but well, that will be major clarification actually then...

In that case, let me explain further: by applying the new look table after the Adobe Standard look table, profile authors will know what their input colors are. All you need to do is look at the rendering you get when applying Adobe Standard, and go from there.

If we replaced the Adobe Standard look table with the profile's look table, you wouldn't be able to observe the device colors you're using as your input colors, because there is no way to see that.

Adobe Standard also provides a reasonable standard baseline for all cameras, so that you only need to build one new profile to work across all camera models with an Adobe Standard profile.

that actually was clear after your first reply - for whatever reason I was thinking that at least with the new DCP (~120Kb sized Adobe Standard) Adobe was getting to the acceptable (similar across camera models) baseline through matrices + HueSatMat LUT table(s) applied before "exposure-related" corrections, but the mere note that you do not replace LookTable was the indication that it is not the case.

Yes, the look table of an enhanced profile is applied immediately after the look table of the DCP profile base.

The RGB LUTs, on the other hand, are applied closer to the end of the image processing pipeline.

So the two different kinds of tables will have different effects on the ways the controls work.
