Camera Raw/Lightroom Classic/Lightroom Ecosystem: Disable built-in lens profile

I own Micro43 and compact cameras, where lens profiles are integrated in RAW files. With software like Capture One Pro, I can easily enable or disable theses built-in profiles. Actually, there is even a slider allowing to enable 0% or 100% of the built-in profile, and whatever percentage in between.

In LR (CC, Classic or LR6), the checkox for enabling or disabling profiles does not work with built-in profiles, which always stay enabled. This seriously limits the possibilities of several cameras which possibilities get unleashed by actual RAW developpers like Capture One Pro.

I'm actually a COP user (after switching from LR) but DAM sucks with COP and this built-in lens profile thing is the only deal breaker for me to come back. So please let users disable built-in lens profiles, or at least offer workarounds.

As a workaround, a dumb "zero" profile that would replace the built-in one (not coming on top of it) could do the job.

Great idea! Allow the "built-in lens profile" to use the same controls as the Adobe provided lens profiles. I usually change the Lens Profile Default Settings to Distortion = 0 and Vignetting = 50 to 100 dependent on the lens. With shorter focal length lenses this reduces the stretching, noise, and aberrations in the image corners and sides.

Also many of the "compact" camera lenses have a high amount of barrel distortion (almost fisheye) at the extreme wide end. I discovered it was possible to recover a considerable amount of raw image data area  being cropped by the built-in lens profile using PS Adaptive Wide Angle Filter in 'Fisheye' mode. I use RawDigger export to TIFF to recover the full image data and then process in PS, but the results would be better using LR's raw converter. This works especially well with images that need transform corrections.

Let me consider a Canon G7X. I could have done the same with other compacts or mirrorless cameras with heavilly distorted lenses, and built-in profiles. I'll take a G7XII sample from dpreview.

This is what you get OOC or developed by LR (soft corners due to heavy stretching)

This is the actual full sensor data (as you can get with C1P, DXO or any RAW convertor I could test, except LR) : there is vignetting but the angle of view is actually (much) wider than 24mm (FFeqvt), and 

This is what you get with a manual crop : by comparison with the Lightroom version, the angle of view is actually larger but LR prevents you to take advantage of your gear and hides large areas of your sensor.

What's wrong ?

In LR interface, we have this dialog :

But when the profile is built-in (as usual with compacts and mirrorless), the "Enable Profile Corrections" has no effect. Checked or unchecked, the profile is always enabled.

So, LR prevents to disable built-in profiles, and prevent users to take full advantage of their gear.

How to solve ?

Let the checkbox work as it should.

Other use cases (mostly wide angle with compact lenses)

Some people love shooting with fisheyes when they prefer to preserve natural and unstreched shapes rather than straight lines. It is often not the case for architecture but in situations such as
  • wide angle portraits
  • wide angle group shots with streched people on the border
  • wide angle landscapes where straight lines are not mandatory
  • wide angle with a priority to sharp corners above straight lines
rectilinerar projection are not always suitable, and people (like me) prefer keeping "distortion"μ.

Only LR forces users to perform rectilinear projections. I have no problem with enbling this by default, but the checkbox should work and the built-in profiles should be possibly disabled.

Note that sometimes, people complain about tiny details. This problem is visible even at very low resolutions. It affects the global geometry of an image. Adobe should let the users some creative possibilies.

I'm late to this party but I hazard the suggestion that the 'built-in' profile issue isn't just about distortion. Unless I am very much mistaken the profile for a Sony E-mount standard zoom (E16-70 f/4 ZA)  purchased last year also adds a certain amount of sharpening. I can find no other explanation for the edge artifacts I periodically see when I process images taken with this lens in Lightroom. It's certainly not a camera issue as images taken with an older (and slightly softer) lens attached to the same A6000 back are entirely free of this problem.

It's my understanding that the Adobe LR and ACR built-in lens profiles apply, only distortion, vignetting, and chromatic aberration correction and not necessarily all of them for specific camera models. Take a look at this post, which may be what you're seeing:

Those built-in profiles can change the sharpening and noise reduction settings. Here's an example from the Nikon Z7. This is a SOC RAW file. It looks to me that Nikon is instructing Lightroom to modify the sharpening and noise reduction settings.

The Z6 and Z7 embed LR develop settings in the XMP metadata of their raw files.  See this thread:  

These embedded develop settings are different, and have different capabilities, from the built-in lens profiles that the cameras also embed in the photos.  The embedded develop settings can be easily disabled using an Import develop preset.  But the embedded built-in lens profile can't be disabled (at least from within LR).

John was quicker than me but he is absolutely right. The sharpening settings for Z6 and Z7 files have nothing to do with the lens profiles that are also built in to the nef files. The sharpening settings are dependent on the in-camera sharpening settings and are done by simply writing xmp camera raw default metadata into the nef file that Lightroom and camera raw pick up. I really wish there was a way to disable the built-in lens profile.
