Lightroom Classic: The full set of lens profiles is unavailable for jpg files even when choosing manually.

Lens profiles for jpg files very limited. Even though Lightroom will not automatically choose a lens profile for jpg files, it seems that users should still be able to assign manually. The list of lenses is woefully short.

Personally, I am not using this function in LR, I am rather using DxO Lab for developing RAW files.

This said, as far as I know, lens corrections are not possible with JPEG format. This kind of correction like the WB correction and Camera correction are only possible with RAW format

This reply was created from a merged topic originally titled Please make a way possible to use RAW Lens Profiles for JPGs.

I Use a manual Irix 11mm F4 Lens.
When i make Timelapses with Sony A7rii i want to choose JPGs instead of RAW to avoid Terabytes of RAWs.
As is use a manual Adapter the Camera did not know what Lens is attached.
When i shoot Raws its possible to correct Lens Distortions with Lightroom manually. (works fine) 
But when i import JPGs these Profiles are not choosable.
The Camera didn`t know the lens. No Distortion Correction is applied from the Camera to the JPGs. 
So there is no understandable Reason to stop me from using this profile. Why are they disabled?

Without the ability to correct the Distortions the Panoramic Stitching didn`t work. This stops my entierly Workflow and forces me to handle much more Data than needed.

Lens profiles in Lightroom and Camera Raw generally only support raw files since JPEGs may already have lens corrections applied by the camera, and there is no reliable, standard way for LR to tell. Many people have wished for the capability of manually choosing a raw lens profile for JPEGs, but that's never been implemented. However, it's straightforward to edit a profile to let it work with JPEGs; see this recipe from an Adobe engineer:

This issue got raised often. One of the reasons that lens profiles created for RAW could be wrong for JPEG is that we don't know the processing history of JPEGs. The JPEGs could be cropped, scaled, transformed in tools like PS. JPEGs could even be cropped on camera via the custom aspect ratio setup. In other words, assumptions on the geometry/optics of JPEGs could be very wrong when a lens profiles built for RAW is applied.

It makes sense that LR wouldn't automatically select the lens profile for JPEGs. But many are asking for the ability to manually select the lens profile.   I don't see the harm in that -- it would be apparent to the user if the profile isn't producing the intended effect. LR could provide a warning, "Applying a raw lens profile to a JPEG may not give a good result."

Hi. I just came from abroad with full card of pictures taken with 8mm in jpeg. Already while taking these pictures I was counting with lens corrections being applied later in LR. This was the first time I was shooting directly into jpegs. What was my surprise when I came back home and found most of the lens profiles are missing from the list, including mine 8mm. There is no way how to do it now, specifically distortion, which is HUGE with my manual 8mm and usual distortion slider is not "strong" enough. What to do now? Why I can not perform lens specific geometry fix for jpeg at first place?

Did try but it works only locally. Corrections made with custom edited profile file does not sync via Lightroom CC cloud.

Another workaround you could use.

1) Make a copy of the photo
2) Select these two identical pictures and merge them into HDR. (Auto Settings seems to work best for me, keeping everything off makes awful result)
3) Apply lens profile as usual with shooting RAW

Of course it will not create any HDR, but the output picture is in .dng format you can apply lens profiles on. 

Even though HDR uses two identical pictures, it alteres the colours and lights a little. I was not expecting that. But if you do this workaround before final adjustements, there is no harm.

An easier way is to simply export the file as a DNG.  However, this does not appear solve the issue with the current edition of Lightroom Classic.  The same limited set of profiles appear for DNG as do with JPEG files.

That is logical. A JPEG exported as DNG is not a raw file. It's still an RGB-file, packed in a DNG envelope.

Any suggestions for a work-around?  The one posted above (changing True to False in the lens profile .dat) does not seem to work, although I could be doing it wrong somehow.

"changing True to False in the lens profile .dat"

Just to double-check, profiles end in .lcp.

In that case, where are they stored? There is a massive data file (.dat) which contains xml instructions for all lens profiles. The filepath to find the folder was different than noted, but I assumed that was due to updates within adobe's file structuring. It was suggested to place the file in:
/Users//Library/Application Support/Adobe/CameraRaw/LensProfiles/1.0

Since that doesn't exist, I found an analogous file tree here:
C:\Users\Evan\AppData\Roaming\Adobe\CameraRaw\LensProfiles\1.0\pscache.dat

It contains the lines noted in the fix:
<stCamera:CameraRawProfile>True</stCamera:CameraRawProfile>

This line occurs for each and every profile in the document. That is where I changed "True" to "False", for the relevant lens profile. If this is not the place to make the change, where do I locate individual files for each profile? Do I then have to modify this file also?

The built-in .lcp profiles are in:

C:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0.

Place the edited copy in:

C:\Users\user\AppData\Roaming\Adobe\CameraRaw\LensProfiles\1.0\.

There may be multiple lines in the file containing:

stCamera:CameraRawProfile="True"

so be sure to change all of them.

Thank you.  Had just done a search for ".lcp" and located that folder.  Is the "- RAW" at the end of the file names just a 'pretty name' or does that need to be changed as well?

I don't think the filename needs to be changed.

Glad you got it working. It's too bad that LR doesn't let you manually apply raw lens presets to JPEGs (perhaps with a suitable warning).
