P: 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.

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.

I voted for this too. What I read somewhere a long time ago is that Adobe made a deal with vendors to auto-apply profiles, as it makes cameras look better. I switched from Canon to Fujifilm and many of my Fujinon lenses have heavy distortion and vignetting that I sometimes would like to keep.

Especially vignetting can be desirable many times, removing it and adding it back is just throwing image quality out the window.

I also feel that Adobe is removing an important learning opportunity here, as automatic corrections can mask the differences between high and low-quality glass.

Adding my vote too. Recently got a Nikon Z7 and this has the built-in lens profile issue. I often want to disable this as I might want the more natural look of vignetting caused by the lens as well as natural distortion instead of having to fake it with the vignette and distortion controls.

Adding my vote for this feature. Other possible solutions:

- Add an "Apply" button to the manual settings that would allow zeroing all values. The initial values are zeroes, but they can't actually be applied by default (i.e., override the built-in profile).

- Create a checkbox or configuration option that would give users the choice to not apply profile corrections by default.

- As suggested, add a selectable "Zero" profile to the list of manufacturer/other profiles.

And of course, allow these settings to be saved as default so they don't need to be applied manually each time.

Thank you.

Pierre: in theory a lens profile could be generated from some exposures where the built-in lens correction had been deliberately "broken", and then this profile could be applied manually onto other photos where the built-in lens correction had been similarly "broken". You would then have separate sliders for turning up and down, or off, the strength of geometric correction, and of vignette correction... assuming you applied this custom lens profile, otherwise you could apply no lens profile at all and rely on manually set corrections instead, or else no correction whatever.

Adobe external profiles no longer characterise CA correction as far as I know, but rather (in response to the CA checkbox) Lightroom can analyse the photo content directly, and then apply whatever lateral CA correction it concludes is most optimal. To be clear, this method does not rely on any pre-existing profiling info at all.

The problem is that I would like to keep the information about the profile (I use it for most of my pictures). All I want is to get able to disable it at will. So erasing the data is not an option for me. I also would like to keep the data for CA correction and vignetting.

I've been told that the new Canon mirrorless also embed lens profiles in the RAW files, but that you can nevertheless turn on/off this built-in profile. That's only for the new Canon, not for the new Nikon Z, which suffer from the same issue as avery other ML. Could EXIFtool be used to switch some flag (in Canon's way) "allowing" LR to disable the lens profile ?

I tried using it with Canon G9X MKII CR2 files and DNG converted files without any success. This is a fixed lens point-and-shoot camera that uses a built-in lens profile. Any ideas?

I am working with Exiftool at the moment, but if you use it for CinemaDNGs/Filming, it's a pain to process 50.000 files two times (1x with exiftool, 1x ACR). It would be much faster and easier to disable the embedded lens-profile and enable my custom settings in one step directly in ACR.

"... By allowing a zoom lens design to have more distortion and vignetting the focal length range and/or maximum aperture can be increased..." and the expense of decreasing resolution when pincushion is corrected (so you stretch vs compress), thank you... not to mention crude noise handling ( Eric Chan @ https://forums.adobe.com/message/3512039#3512039 )
