Lens distortion corrections in Camera Raw?

Chromatic aberration, lens vignetting, post crop vignetting
are possible in Camera Raw.
Why not have access to lens distortion corrections in CR?

Maybe show us a screenshot of what you see on the system that isn't want you expect. What version of ACR are you using in each? It should be visible in the title bar of the ACR plug-in if you unmaximize it, or you can do About Plug-ins / Camera Raw in PS.
Here is the Manual tab of ACR 6.7 on Windows in CS5:

Digital Camera RAW Update 5.02 breaks Sony RX100 lens distortion correction (AGAIN!)

Just like with the Digital Camera RAW Update 4.08, the latest 5.02 update breaks the Sony RX100 lens distortion correction again. I'm reverted back to 5.01 until this is fixed.
From your Time Machine backup, restore the previous versions of
/System/Library/CoreServices/RawCamera.bundle
/System/Library/CoreServices/RawCameraSupport.bundle

Yes, I noticed it too, but I wasn't certain it was 5.02 that did it as I sold my RX100 and haven't processes any files for a while. Then as part of the NR discussion here I looked at some old RX100 files, and the distortion correction now disappears. Unfortunately I can't really revert to 5.01 because I was waiting on the A7 support 5.02 brought.
Apple are aware of it, so hopefully the fix will be quick to arrive.

Perspective/lens distortion correction

About the only thing I ever have to go out of LR2 to do is correct for perspective or for lens distortions (esp. on wide angle lenses). I know this might not be an easy thing to fit in the interface, but it'd be very useful. Especially if you can set it up to do a stored lens distortion correction for a given lens at a given focal lens (+ maybe focus distance).

I hope y'all don't mind if I think aloud a little more here.
We've been talking about perspective correction and lens distortion correction as if they were just about the same. They aren't.
Lens distortion correction is a fairly complex warp, but one that is completely determined by the lens and focal length (please corect me if I'm wrong). The main use of it would be to correct for the lens defects, not to create an artistic effect (like CA repair). It could therefore very reasonably be done as a preparation step, as with the Olympus cameras that actually store some correction information. It would be of relatively low user value to be able to change it later, and it would be much harder to implement.
Perspective correction is most definitely a user-driven correction. Not only does LR not stand a chance of figuring out what to do automatically, there would also be many cases where you'd want to correct in one dimension but not another, correct somewhat less that 100%, or in other ways fiddle with the amount of correction. Fortunately, it is a much simpler correction, merely the application of a small transformative matrix. Unlike lens distortion correction, it doesn't turn circles into strange wobbly shapes, but merely into ovals.
Let's take a look at the local adjustments: Crop, rotate, red-eye, spot removal, graduated filter and adjustment brush.
Crop would be well-nigh impossible to mix in with lens distortion correction, another reason to have the correction applied first. With regards to perspective, it should behave more or less like it does towards rotation.
Rotation can actually be done internally using the same operations that perspective correction would, but should probably still be separate in the interface.
Red-eye and spot removal both operate on horizontal-vertical ovals (restricted ovals for spot removal). These would be awful with user-adjusted lens distortion correction, even more reason to have that be an initial step. Perspective correction would stretch them somewhat. What happens when the user makes a dust spot fix, then fixes the perspective, then attempts to adjust the dust spot fix? We end up with the same situation as with vignetting: That there are pre- and post-crop versions. This distinction would now have to extend to pre- and post- crop+rotate+perspective adjustments. Obviously, you'd also want to be able to spot remove based on the corrected image, and it'd be strange to have a tool that's bent. It may be necessary to separate out dust spot removal from "subject matter removal" (including red-eye), as dust spotting should always be before perspective correction.
Graduated filter was really the thing that convinced me that the two corrections need to be split. Applying lens distortion correction after graduated filter would lead to a bent 'horizon line', a very bad thing indeed. Fortunately, it would be fairly resistant to perspective correction, though not entirely: If the horizon does not follow the perspective correction axis, the outer lines ought to tilt together. Probably overkill, though.
We already have an example of a similar situation: Red-eye removal and rotating. Try making a red-eye correction, then rotating the picture sharply. The red-eye oval will stay in the same position, even though that moves it from where it was supposed to be. I guess graduated filters could behave similarly.
The adjustment brushes are probably the simplest: Since they're already amorphous shapes, they can "simply" be bent and distorted along with the corrections and still make as much sense afterwards. Except if you want to use them to correct lens errors, but I don't know how often you'd want to do that.
Perhaps distortion correction and pre-crop vignetting should belong together. They would certainly interact.
That's my $0.02 plus inflation.

Lens Distortion correction not working on tonemapped jpg files

I have a series of photos exported from Lightroom 2 that I HDR tonemapped in Photomatix. Unfortunately after a disk failure I do not have the original RAW files and only have the 100% jpg saved tonemapped files from photomatix.
Now that Lightroom 3 is out I wanted to try some lens distortion correction on them. I imported them and immediately noticed after enabling the lens profile corrections and choosing my lens that although chromatic arberration and vignetting works there is no effect at all with the distortion correction! Even when I slide the slider from one side to the other absolutely nothing changes.
I tried it on other raw files and it works fines. I tried it on jpgs that I have that have not been combined and tonemapped in photomatix and they work fine. It is only the jpgs created from photomatix.
Is there something about the exif data that I am not considering or any other explanation as to why the photomatix jpgs won't take any distortion correction? thanks

If it's working for other jpg's, (and I though it didn't work on jpgs, so who knows?) then it does sound like the photomatrix program is wiping out the exif information that is needed.
Did you try using a viewer to look at the exif info, both before and after, to compare? Maybe there is a setting (in photomatrix) that you are missing when you save data?
Sorry, don't know photomatrix, so just offering generic ideas in the hopes it sheds light..
Cheers!

No lens profiles in the Camera Raw

There are no lens profiles in the Camera Raw Lens Corrections tab. How do I add them?

Assuming I read your post correctly, and that you're trying to use Lens corrections on JPEGs and TIFFs... I believe there's a completely different set of profiles for correcting already "developed" images (such as JPEGs and TIFFs). If I recall correctly (and it's been a while since I read about this), it's the same set that's used inside Photoshop for the Filter - Lens Correction tool (I hope someone here will correct me if I'm wrong, but I'm sure I read this somewhere).
If your lenses are known to Camera Raw when you develop raw files, I suggest you will need to go all the way back to your Raw file and reprocess it from that stage. You'll get a better result anyway.

How to Save Camera Calibration and Lens Correction in Camera raw 6.1

I downloaded and installed the Camera Raw 6.1 release candidate. I open an image and set the camera calibration and the lens correction to auto for Nikon. I save these settings as new Camera raw defaults, but when I open other images, the changes were not made. How can I save these items as defaults?
Swila

Swila, were your "other images" previously edited in Camera Raw? I.e., do they already have saved image settings? The defaults that you save via the flyout menu will only apply to new images, or if you reset an existing image to the defaults. (e.g., choose "Camera Raw Defaults" from the flyout menu).

Vignette Correction + Lens Correction in Camera Raw / Lightroom

Ok i merge 2 requests for both camera raw and lighroom...
-> Vignette Specific Correction: Using preset for Lenses like Canon DPP Does for Peripherical Illuminance Correction, the vignette tool in lighroom is good but can't adapt to a variable vignette profile of each lens...
+ Ability to user to add them using a png 24 bit or similiar for Lenses not present on the DB (think using old lens, with adaptors, old zeiss without automatic controls that obviously will be not profiled by Canon, Nikon, Sony.. for their bodies)
-> Lens Correction based on Preset... + exif reading like in photoshop cs5 + manual adjustments
thank you

So you use Photomatix to create a 32-bit HDR file and then tone that 32-bit file in ACR? Are the Photomatix 32-bit files that much different than the PS-CC 32-bit files? The Photomatix 32-to-16-bit conversion is quite a bit different and perhaps preferable, but I didn’t realize the 32-bit result file is also that much different. It’s been a while since I’ve tried 32-bit HDRs and even longer since I’ve tried them in Photomatix so things may have changed or I’ve forgotten.
If you are using Photomatix, then you are not using an Adobe raw conversion at all, so Adobe settings and raw lens profiles are not seen and used at the initial raw-conversion stage in Photomatix.
The choices would seem to be that you can use Adobe products to create 16-bit TIFs as an input to Photomatix, or hack an Adobe raw lens profile to be used with non-raw files in ACR, or do your lens profile corrections after you’ve saved your 32-bit HDR image back as a 16-bit one and use the lens corrections area in Photoshop if that is still possible, nowadays.

Diference between filter Lens correction and Camera Raw Lens Correction

Whats is the main diference between tools: filter lens corection and Camera Raw Lens Correction.
I am using PhotoShop cs6, OS Windows 7
I already asked support team in Poland, but they send my back message: "we dont support any longer PhotoShop sc6"

Swila, were your "other images" previously edited in Camera Raw? I.e., do they already have saved image settings? The defaults that you save via the flyout menu will only apply to new images, or if you reset an existing image to the defaults. (e.g., choose "Camera Raw Defaults" from the flyout menu).

Nikon D700 vignetting correction vs. camera raw lens corrections

The Nikon D700 has a menu item for correcting lens vignetting. I'm wondering should I rely on just that setting or use the vignetting correction feature in Camera Raw or both? Looking for some feedback/advice on this. Thanks.

I have not used vignette control in the D700, but my understanding is it only applies to the in camera processed JPG and TIFF images and not to the NEF. If you had this set in the camera it probably would also apply to NEF files processed with Nikon Capture NX2, but not Camera RAW.

Over correction in Camera raw

Hello,
I have a problem with functionality of camera raw module 8.3 in Adobe CS6.
The module is over correcting the RAW(.nef) images when selecting "Enable lens profile Corrections".
The lens are selected right( nikon 24-70 2.8) but it's over corrected in the corners of the image(it's too bright after correction)
Why this happens after 8 editions of the ACR module?
I attach image with the demonstraion.
aperture 2.8 shutter speed 1/400 iso 1400
1.Why that happens?
2.Will it be corrected?
3.If yes, when?
Thank you

Swila, were your "other images" previously edited in Camera Raw? I.e., do they already have saved image settings?

Lens/distortion correction updates?

I haven't been able to find any reference to how new profiles for lens corrections will be updated in the new Lightroom, anyone have any insight?

My understanding from comments on the Lens Creator forum is that new profiles will be made available as part of the Lightroom and Camera Raw dot releases that ship every 3 or 4 months. These normally include new support for new cameras.

Lens Distortion Correction Documentation?

I have seen in some discussions that LR corrects lens distortion for some lenses and some cameras. I have not been able to find documentation that indicates what cameras and lenses are supported for this - either for LR2.3 or 3.0beta. Is that documentation available somewhere?
Thanks!
David

Well, I guess that would be why I couldn't find it. ;-)
I'll try a more specific question. Are any DSLRs supported by the distortion correction? Specifically, I'm interested in a Canon EOS 5D, and what lenses (if any) Adobe has profiled for distortion with this camera.
I am hopeful that when LR3 comes out of beta, it will have distortion correction for most or all supported cameras and lenses, and that at least some of the specifics will be documented.
Thanks!

Lens distortion correction in Premiere CS6?

I'm trying to correct the distortion caused by a wide-angle lens in Premiere CS6. From what I can tell, there is no filter or transform / distort feature within Premiere itself. I followed the steps in this tutorial to open the MPEG4 in Photoshop, apply the lens correction filter, and then export the video again to be re-imported to Premiere. http://podcasts.creativecow.net/adobe-premiere-tutorials-podcast/correcting-lens-distortio n
However this tutorial is for CS5. I am seeing no adjustment or filter layer in my layers panel, as it appears in the tutorial. When I go to export the video, it seems the Adaptive Wide Angle filter or the Lens Correction filter has only applied to a single frame of the whole clip. Bummer.
Any other suggestions for fixing lens distortion in Premiere?
Thanks!

Both these replies are a bit rude and unhelpful. I am editing in Premiere, and I am not very familiar with it. The question is about how to fix lens distortion in Premiere. Maybe there's a way to do this that I'm not aware of...? That's why I asked the question! There's nothing about it that I could find in the forums. The only fix I found didn't work—which was to use Photoshop *integrated with Premiere*. And two people tell me to use AEFX without pointing me in any directions of how to do that. Useless.
Anyway, I found some information that *was* helpful. This tutorial demonstrates that one critical step was missing from the prior tutorial, which is to convert the video layer to a smart object before applying the effect:
http://www.protechreviewgroup.com/tutorialsinformation/tutorial-fisheye-correction-in-phot oshop-for-gopro-hero-hd/
The same person provided a tutorial on how to do this in AEFX:
http://www.protechreviewgroup.com/tutorialsinformation/tutorial-fisheye-lens-correction-in -after-effects-for-gopro-hero-hd/
Now that these steps are taken, I have to take the footage back into Premiere. It's a workflow question. Other video editing software has this kind of stuff built-in to the effects panel.

Lens distortion correction

I would like to know if there is way to correct a lens distortion (Barrel Distortion) inside Lightroom. If not, how can I do it.
ex. Nikon D70 lens 18-70mm

And this is really a thread for the main forum. This is Feature Requests, and this one is already in.

I've done spot healing in my images but want to change lens distortion corrections. Does it matter?

- I originally corrected all the lens distortion in my images with the default Adobe lens profile for the lens, and also done all the spot healing too. However, I now want to change the lens distortion profile to a profile that i've made instead. The Adobe default lens profile and the one that i have made give different distortion corrections (Adobe's is a bit too strong).
- Will all the spots chosen in the spot healing still be mapped correctly? i.e will the source points for the spot healing and the area i'm sampling from still be in the correct positions after adjusting for the new lens distortion?
- Does Lightroom allow for this, or do i have to re-do all the spot healing?

Hey Paul,
Well, you could just try it to find out . But the answer is: Adobe adjusts spots (and paint, and red-eye...) to accomodate lens corrections. It's one of the reasons it is recommended to leave lens corrections until last if your Lightroom is performance challenged, i.e. it takes some horsepower.. (me? I like having lens corrections done up front, despite the performance hit).
