Lens correction with integrated lens profile from raw file

Hello,

recently I have a Nikon D780. Apparently, the raw files include an "built-in lens profile", with which LR automatically performs the lens corrections. In the section Lens Corrections of the Develop module it says as an info text: "This raw file contains a built-in lens profile for correcting distortion... The profile has already been applied automatically to this image".

Unfortunately, it is not possible to switch off this correction with the values provided by Nikon in order to alternatively apply the profile that is provided by LR.

I would like to use the LR corrections, because with my old camera (D750) they were always better than those of Nikon.

If you select the LR corrections anyway, there is actually an overcompensation of the lens errors.

Does anyone know if there is any way to turn off this automatic lens correction with the lens profile embedded in the raw file and apply the LR corrections?

Thank you very much for your support!!!

Greeting,

pemiwi.

You can't turn off the built-in lens profile from inside LR. There is a way to disable it by modifying the NEF, which I don't recommend. What specifically is wrong with the D780 built-in lens corrections? Knowing that I might be able to makes some suggestions. Please add your 'Me To' vote and 'Follow' at the below request for ability to disable built-in lens profiles.

Hello,

thank you for your quick answer!

In my opinion, the corrections are simply not as good as those of LR or DxO. This applies to both the correction of distortion and the correction of vignetting. I would have to correct manually with the sliders, whereas I never have to with the LR corrections.

So if you knew a way to manipulate the raw files, I would be very interested and would like to try it out!

Thanks for your support!

Is this happening with a specific lens and/or aperature setting. I downloaded Nikon D780 NEF files shot with the VR 24-120mm f/4G lens that show significant vignetting at 24mm F4, but none at 24mm F8.

I think the built-in corrections provided by Nikon are simply not as accurate overall as those provided by LR or DxO. Of course, this is especially visible with lenses/focal lengths/aperture where there is strong distortion or vignetting. I had therefore used DxO instead of Nikon SW for years and switched to LR two years ago.
What's more, the built-in profiles for each lens contain the corrections for distortion, vignetting and chromatic aberration, only two or one or none of them. So if you want to apply all corrections to all images by default, you first have to sort by lens, check which corrections have already been applied and then manually add the missing ones. Therefore I would prefer to simply switch off the Nikon corrections completely...

Thanks once more 🙂

In the screenshot I supplied the VR 24-120mm f/4G lens at F4 exhibits ~-1.5 EV vignetting in the extreme upper right corner with the built-in lens profile. With 'Enable Profile Corrections' checked and the VR 24-120mm f/4G lens profile selected the 100 Vignetting setting looks perfect with no measurable corner vignetting. I checked a few more NEFs shot with the same lens at F4 and 24mm and I see the same results with 'Enable Lens Corrections' fully correcting the vignetting, but not over-correcting. Next I checked a NEF shot with a Nikon 50mm F1.4D lens and With 'Enable Profile Corrections' checked the image showed pin cushion distortion at the 100 Distortion setting. So that's over-correcting the image. Clearly something is wrong with these Nikon built-in lens profiles or at least how Adobe is applying them.

 

It also appears Adobe is not creating lens profiles for lenses that use built-in lens profiles such as the Nikon Z series. So it's important that this issue be fixed. I suggest creating a new 'Problem' report at the below Photoshop Family forum, which is monitored by Adobe Engineering. You'll need to provide download links for NEF files that exhibit the issue. The best way to do this is to shoot some test images of a very evenly lit subject such as a large piece of posterboard. position the posterboard so that it fills the frame with exception of the top and bottom edge, which should be just visible in the frame. This will allow checking for distortion. If you can do that and post the links back here I'll assist you with creating the problem report. Makes sure you also add your 'Me To' vote and 'Follow' at the post requesting ability to disable built-in lens profiles. Thank you!

I will try to provide some meaningful images. However, this will continue over Easter...
Apart from the quality of the corrections, not all corrections are available for all lenses via built-in correction:
16mm/2.8D: Vignetting
80-400/4.5-5.6G: no correction
16-35/4G: Distortion, Vignetting, Chromatic Aberration
24-70/2.8E: Distortion, Vignetting, Chromatic Aberration
I haven't tried all my lenses yet. Surely there are other combinations of what is provided and missing.
Result: If I want to apply all three corrections to all my images by default, I have to sort my images by lens and then add the missing correction of LR depending on the lens. This is cumbersome and annoying for me because it is superfluous.
Up to now, all my Nikon lenses (D, G, E) had the appropriate parameters for distortion, vignetting and chromatic aberration at LR.

(I now also voted and follow the post at photoshop_family)

"Apart from the quality of the corrections, not all corrections are available for all lenses via built-in correction."

I've noticed that when clicking on the 'i' icon to see what is corrected. Olympus cameras say "built-in lens profile for correcting distortion and chromatic aberration with no mention of vignetting correction. However, all of the ORF raw files I've checked appear to have no visible vignetting. The only camera I own that uses a built-in lens profiles is the Canon G9X MKII. It also says lens profile for correcting distortion and chromatic aberration with no mention of vignetting correction, but there's no visible vignetting! Sony cameras say ""built-in lens profile for chromatic aberration" and nothing else. However, Adobe does provide lens profiles for Sony lenses that are used to correct distortion and vignetting.

 

So the best check for the Nikon D780 built-in lens profiles is as I outlined. Adobe Engineering (and you!) can then see first-hand with your test image files how much distortion and vignetting that remains uncorrected. Take your time, there's no rush. If you have any questions concerning the test setup please let me know. I suggest shooting with each lens at its widest aperture and also at F8. Try to use the largest target possible as lenses typically exhibit additional distortion and/or vignetting when set near their closest focusing distance.

I have now made a few test shots and some comparisons on distortion and vignetting. Can you please help me with how I can add the pictures to the text (about 230 MB in total)?

Please use Dropbox or other file sharing site and upload all of the files. You can use subfolders if that's helpful. I'll review them and we can discuss next steps concerning reporting the issue to Adobe.

Here are now my comparison shots. However, I found it difficult to create an exact (artificial) test setup, so I took "normal" pictures, which in my opinion are nevertheless meaningful.

Result: The best results are achieved with the correction for distortion and vignetting provided by LR, but only if the built-in correction of the raw files is switched off.

 

Distortion Nikon VR 16-35 mm, f/4G at 16 mm focal length:

https://www.dropbox.com/sh/dgkfda4yj8lhwt4/AABbQsbRy66q-jwSD5bF5ZHQa?dl=0

The pictures were created as follows

  • 1.nef: Original raw file with built-in (and applied) Nikon correction, 16 mm, f=4.0
  • 1a-integrCor.jpg: JPG from LR directly from the raw file with built-in Nikon correction
  • 1b-intergrCor_LRCor.jpg: in LR the LR correction activated, then JPG
  • 1c-DxO-DNG-woCor.jpg: DxO as raw converter, without correction as DNG to LR, no built-in Nikon correction, no LR correction, JPG from LR
  • 1d-DxO-DNG-LRCor.jpg: DxO as raw converter, without correction as DNG to LR, no built-in Nikon correction, correction within LR, JPG from LR
  • 1e-DxOCor-DNG.jpg: DxO as raw converter, correction in DxO, as DNG to LR, no built-in Nikon correction, no LR correction, JPG from LR

Findings:

  • the integrated correction 1a causes a correction compared to 1c (uncorrected), but not very good
  • when selecting the distortion correction in LR (1b), the integrated Nikon correction is not switched off automatically, that's why the total correction is too strong, compare 1d (well corrected)
  • 1d: if the LR correction is applied without the built-in Nikon correction, the result is very good
  • 1e: the DxO correction is not sufficient at the edges

 

 

Vignetting Nikon VR 28-300 mm, f/3.5-5.6G at focal length 300 mm:

https://www.dropbox.com/sh/pbt2drb7ntyh6da/AAC7UAVRef5lXB73B3VqS751a?dl=0

The pictures were created as follows (same procedure a..e as for distortion)

  • 2.nef: Original raw file with built-in (and applied) Nikon correction, 300 mm, f=5.6
  • 2a-integrCor.jpg: JPG from LR directly from the raw file with built-in Nikon correction
  • 2b-intergrCor_LRCor.jpg: in LR the LR correction activated, then JPG
  • 2c-DxO-DNG-woCor.jpg: DxO as raw converter, without correction as DNG to LR, no built-in Nikon correction, no LR correction, JPG from LR
  • 2d-DxO-DNG-LRCor.jpg: DxO as raw converter, without correction as DNG to LR, no built-in Nikon correction, correction within LR, JPG from LR
  • 2e-DxOCor-DNG.jpg: DxO as raw converter, correction in DxO, as DNG to LR, no built-in Nikon correction, no LR correction, JPG from LR
  • 3.nef: Original raw file with built-in (and applied) Nikon correction, 300 mm, f=8
  • 3a-integrCor.jpg: JPG from LR directly from the raw file with built-in Nikon correction
  • 3c-DxO-DNG-woCor.jpg: DxO as raw converter, without correction as DNG to LR, no built-in Nikon correction, no LR correction, JPG from LR
  • 3d-DxO-DNG-LRCor.jpg: DxO as raw converter, without correction as DNG to LR, no built-in Nikon correction, correction within LR, JPG from LR

Findings:

  • The 28-300 mm lens still requires correction for vignetting at 300 mm and aperture 8 (3c, uncorrected)
  • With open aperture (5.6) the integrated correction 2a provides a correction compared to 2c (uncorrected), but not very good compared to 3a/3d (aperture 8), or compared to 2d (LR correction)
  • when selecting the vignetting correction in LR (2b), the integrated correction is not automatically switched off, which is why the total correction in the outermost corners is too strong compared to 2d (LR correction)
  • 2d: if the LR correction is applied without the built-in correction, the result is very good
  • 2e: DxO correction, also very good

The simplest solution to this issue is the ability to turn off the Nikon built-in lens profile and use the Adobe provided lens profile. Towards that objective I suggest adding your comments at the below request for same. Provide a link back to this post for more details on your test results. I would note that your issue is that the Nikon lens profiles do not fully correct vignetting and distortion and that some lenses only correct one of these lens aberrations. This will add a 2nd important need for the ability to turn off the built-in lens profiles. After you've added your comment at the below link please add a reply back here and I'll review it and add my own comments for reinforcement. BTW- The Dropbox image files do demonstrate the issue so you should mention that in your comment with the link to this post. Thank you.

Hey,
I have just installed Lightroom Classic 9.2.1 and as far as I can see all the built-in Nikon corrections are switched off. There is not even the "i" symbol anymore that indicates that the raw file contains correction values.
For me, this would actually solve the problem!
