Accuracy of Lens Correction in LR3 or 4

Hi! I recently bought my Fuji X10 und downloaded LR4 (beta). Im quite new to LR & RAW, but learning fast.
Since there is no LCP for the X10 available yet, I'm doing lens correction manually. But the manual correction is quite limited, especially for the 28mm wide angle distortion of the X10.
My efforts result in almost perfect horizontal & vertical lines in the center, but especially the horizontal lines spread towards the edge.

Now I would like to know, if a later available LCP would correct this further and straighten all lines? Hoping not to need Photoshop to do the job.
THX for any comments.

Manual lens correction model is limited and only account for lower order distortion terms. The distortion used in the LCP is more powerful and can account for higher order distortion terms. You can build your own custom lens profiles using the Adobe Lens Profile Creator http://labs.adobe.com/downloads/lensprofile_creator.html. Or see if others have built and shared the same lens profile using the Adobe Lens Profile Downloader.

How to set Lens correction in LR3

Hi,
I am sure this has been answered before but I can't find any answers in LR Help, here or google.
Is there a way of setting the "Lens correction" in LR3 to be on by default? as it is now I have to se tit for each image.
thanks
Chris

You can do this by updating the 'Develop Default Settings.'
1) Open an image in the Develop module and hit the 'Reset' button in the right bottom control panel.
This is your 'Current Default Setting'
2) Go to Lens Corrections and check the 'Enable Profile Corrections' box. If necessary select 'Make' so the lens appears.
3) Go the toolbar (top of screen) Develop> Set Default Settings> Click on Update To Current Settings.
You will need to do this for each camera model you are using in LR.
You can update pictures currently in LR using Develop Settings 'Copy' & 'Paste' or 'Sync.' Select only 'Lens Profile Corrections' in the 'Synchronize Settings' options popup. Keep in mind this will overwrite previously adjusted images with the 100 default 'Amounts.'
You can also modify the 'Lens Corrections' Profile defaults separately for each lens by making the changes and clicking the 'Setup' up/down arrows and selecteing 'Save new lens profile defaults.'

Batch processing lens correction in LR3

Hi folks,
my questions today are best practise questions:
First:
What is the best way to apply the auto lens correction to already imported images in LR3?
Second:
Is it possibe to do auto lens correction during the import process?
Thanx for your support
JK

1. Select desired images, go to Develop, and click the "Enable Profile Corrections" checkbox in the Lens Corrections panel.
Note that you will need Auto Sync enabled for this to work. In Develop, on the right panel, there is a "Sync..." button with a little switch to its left. If you click that switch, that will enable the Auto Sync feature, and the button will be renamed to show this.
2. Yes, make a preset. Namely, pick an image and turn on profile-based lens corrections (see previous step). Go to Develop menu and choose New Preset... In the ensuing dialog box, check the "Lens Corrections" box (and whichever other boxes you want to be included in the preset). When you import your images, select this as your Develop preset. This will cause lens corrections to be applied to all images that are imported.

Where do I get Lens Profile for lens correction in LR3

I have LR3 and need help figuring something out. I mainly shoot with a Tamron 24-70mm. LR3 doesn't list this lens under the lens correction so I can't correct any of the lens distortion. Anyone know where/how I can locate/install this profile? Do I get this from Adobe, Tamron, etc?

There are three Tamron 24-70 lens profiles, but all were added to the LR 4.x series:
http://helpx.adobe.com/x-productkb/multi/lens-profile-support-lightroom-4.html
So the obvious solution is to upgrade your LR to 5.x for $80, or sign up for PS-CC+LR5 bundle at $10/month (for a limited time).
A more complicated way to get these profiles is to install the latest DNG Converter which includes all lens profiles, then copy the lens profiles you need over to the third-party lens profile under your Users folder and LR 3 should pick them up, assuming that folder hasn’t changed places between LR3 and LR5.
I am not a Mac person, but on Windows, the DNG Converter installed profiles would be under:
C:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0\Tamron
And the place to put them is:
C:\Users\yourusername\AppData\Roaming\Adobe\CameraRaw\LensProfiles\1.0\downloaded
AppData is a hidden folder so you just have to type it into the Explore address area and hit Enter or turn on hidden folders in Explorer or type %APPDATA% in Explorer and hit Enter will get you down to the Roaming folder.
You can find the latest DNG Converter at: http://www.adobe.com/downloads/updates

Lens correction profiles LR3.4 Mac

I use a mac.
I shoot raw.
I created lens correction profiles for my camera and a few lenses. I uploaded them to Adobe. The lens corrections show up in Adobe Camera Raw but not in Lightroom. ACR "looks" for the .lcp files in the Library/Application Support/Adobe/Camera Raw/Lens Profiles/1.0
Where does Lightroom look for the .lcp files? Or does it use them a all? There is a large list of supported lenses in the dropdown menu, just not the ones I created.

QUOTING: There is a second Lens Profiles Default folder as well.
Where is this elusive second folder? I put copies of the profile in the /Downloaded folder as wel, but Lightroom still doesn't see them.

LR 3, Pshop CS3 and lens corrections: wha'?

Perform lens corrections in LR3. Open in Photoshop CS3.
And the lens corrections are not applied. Repeatable.
Right now I'm having to finish the PSD, the syncing the (ignored) lens corrections from the raw file to the PSD.
Where's the hidden Do What I Asked command for lens corrections?

Hm. I would assume that LR3's engine would render the PSD, then open it in Pshop.
Because (thanks to your note) I see that I can export a righteously-rendered PSD and, as a post-process, have it open in Pshop immediately.
Thanks, Lee Jay.

Lens correction settings in LR3

Hi guys! I have downloaded LR3 yesterday and played with trial version for a few hours now. Looks like a very welcome upgrade over the 2.x version. However I cannot fully appreciate the way lens corrections module is supposed to work.
I am a nikon user with 28-75 Tamron lens. After setting "custom" lens correction profile and choosing Tamron as lens manufacturer, LR3 accurately suggests my lens model and assigns an existing adobe profile. So far so good. But there is one thing that keeps me from feeling all happy and excited about this new feature: Lightroom would not allow to save different default settings for various focal lengths. For instance, the named above 28-75/2.8 tamron lens has somewhat considerate barrel type distortion at 28mm, and at the same time at its maximum of 75mm geometry distortions are almost non-existent. So while I am happy with how LR3 handles the wide angle distortions, it makes things a lot worse with telephoto range when I apply default lens corrections.
Hence the question: can I somehow make settings in lens corretions module specific to the focal length used? Of course, I would like LR to do that for me, but since it cannot, is there any walkaround? Tweaking settings for each shot is time consuming, and I see no reason not to make this process a little bit more automated.

Adani2, I have encounter similar problems with the same lens on my Canon 1D Mark III (a 1.3x crop camera).
The quick answer to your question is no. There is no setting in Lightroom that allows for correction at a specific focal length, apparently the software is suppose to automatically determine that. I use to have a D80 with the Tamron 28-75 before I switched to Canon. So I decided to process a few shots with LR3 to see if your problem was the same as what I encountered on my 1D3.
I used LR3's lens correction on three pictures, each a different focal length (28, 40, and 75). At the extreme ends, I found 28 and 75 to not vary much from the same image corrected with PTLens (the current progam I use to correct lens distortions). However, at 40 I ran into the same cropping and over correction problem I did with my Canon 1D (albiet it is much worse on the 1D than the D80). It is discussed more in depth here: (http://forums.adobe.com/thread/656057?tstart=30). Below is a picture taken at 40mm (f2.8) with the Tamron 28-75 on my old Nikon D80 with the "corrected" image overlayed on top (opacity 50%):
Before auto aligning of layers in Photoshop:
After auto aligning of layers in Photoshop:
Interestingly, the difference between PTlens and the original image for the above shot is virtually zero which is consistant with reviews about this lens (http://www.photozone.de/nikon--nikkor-aps-c-lens-tests/291-tamron-af-28-75mm-f28-sp-xr-di- ld-aspherical-if-nikon-lab-test-report--review?start=1). Why LR3 believes there is distortion when there isn't any is rather perplexing.
My suggestion, for this lens on a crop body, would be to not bother making any lens corrections except for critical pictures (e.g. architecture) taken around 28mm. The distortions for this lens are, for all practical purposes, negligible on cropped camera bodies.

LR3 Lens corrections not transferred to external editor

When I use the new Lens Correction panel in LR3, then transfer the image to PS (CS4) for further editing using the Edit In command, the Lens Corrections are not transferred, although everything else is.
Details:
The original image is a .dng file.
It is transferred to PS as a 16bit TIFF.
If I EXPORT the image as a 16bit TIFF file, the file image DOES contain the Lens Corrections - it is only when I use the 'Edit In Adobe CS4' command that the problem occurs.
I currently have v5.7 of Camera Raw installed in PS, which doesn't support the Lens Corrections - I don't use it, and so haven't bothered to download the latest version, but surely LR is doing all the processing itself, and won't be using the PS version of Camera Raw?
Any thoughts from anyone?
Cheers
Steve

I understand where you're coming from Steve, but it's always been the same. They don't make the ACR plug-in backwards compatible for older PS versions, as the continued development is one of the things upgraders are paying for. If they spend resources on backwards compatibility, it's not really fair on those who are paying for the upgrades, and could limit the improvements in the new releases.
LR3 works great on its own, and will render a file itself with all of the settings applied, but that does mean you have a file on your hard drive. If you want direct PS integration, it's the PS license fee that pays for that. That said, they did update and bring out 5.7, which they wouldn't usually have done, so if you're not using the lens corrections, opening directly into CS4 will be an almost perfect match, apart from some minor minor tweaks.

LR3 can't read lens correction in PSD files.

I've done lens correction in my raw file.
After opening in in Photoshop CS4, I've made some adjustments in tone and sharpen, and save as
a PSD file, with the same name as raw file.
Comparing the two files, Raw and PSD, the look quite different about the correction lens results.
In PS they looks like the same one, but in LR3 they are not.
It look like the raw file without lens correction.
It's a big issue if I want to export that psd file or even generate other files from it.
Thanks in advance for any help.

You need at least ACR 6.1 + Photoshop CS5 to interpret lens corrections in Photoshop. CS4 cannot do it.
You only option is to set Photoshop as a secondary editor (check Prefs in Lightroom) and let Lightroom render the image before sending it to PS.

Copy/Paste settings always includes lens corrections even if not ticked? (LR3)

I'm having trouble with copy/paste settings on LR3, in that whenever I copy settings and paste them onto other images, the settings for the Lense Corrections section are always transferred, even though they were not ticked in the copy settings dialog. Can anyone else confirm this is a bug or am I doing something wrong?
Edit: Should have mentioned, LR 3.0, Mac OSX 10.6.4, iMac i7.
Thanks,
David

I CANNOT reproduce that.
Do you have the lens correction box unchecked? or do you just have the four boxes under that hierarchy unchecked?

LR3: Losing Lens Corrections

When using "edit in another application" (yes, editing a copy with Lightroom adjustments) with LR3 and sending to Photoshop, I am losing some of the lens corrections, specifically, the lens profile settings and the manually selected transform settings. Manually selected CA and vignette settings are not affected.
Any ideas, or just one more bug in a long list for LR3? As it is, one of the main features I upgraded for appears to be useless to me.

Lightroom should be offering you the option for it to render the file using Lightroom instead of ACR as it did in previous version mismatched situations (LR2 and CS3 for example), but for some strange reason it doesn't. The only workaround I know is to use an export preset that exports to 16-bit prophotoRGB tiff in the same folder as the original and automatically opens CS4 on it and adds it to the catalog. This has functionally the same result as using edit in, but will render the lens corrections.
The alert can be made invisible by checking a box and the odds are high that this is exactly why you can't see it. Go to Lightroom Preferences and reset the the promts - Reset all warning dialogs

Manual Lens Correction in Lightroom 4

The Manual Lens Correction sliders in Lightroom 4 seem completely useless. They aren't working the same as they do in Lightroom 3. Instead of being able to fix keystoning of images, now the horizontal and vertical sliders just stretch or distort photos. Is this a bug? If not, is it possible to go back to the functionality from LR3? If this isn't possible, I'm probably going to switch back to Lightroom 3, since this is one of the program's most useful features.

Lee Jay wrote:
... This functionality hasn't changed at all for me - it works exactly as before.
I think so, too.
See my example in the feedback forum demonstrating the different effect of the manual transformation sliders depending on the angle of view: http://feedback.photoshop.com/photoshop_family/topics/i_would_love_automation_in_the_lens_ correction_manual_panel : There is an automatic aspect ratio correction, and for photos taken with a rather small angle of view, this is mostly a stretch/distort. Which is totally correct IMHO (and hasn't changed since LR3).
P.S. I don't know which angle of view LR assumes for photos w/o information about focal length and sensor size (probably 50mm focal length and 35 mm film format ("full format") sensor.

Lens Correction Manual Slider Bug!

Hello,
I've been having a problem with the Lens correction Manual Sliders. Constrain Crop selected.
The vertical and horizontal sliders are behaving more like the distortion slider.
When sliding left or right they are pulling from the center, rather than the right or left end.
Also, with the scale slider....If I scale down it shifts to the right. when I reset all the sliders to zero.
The image doe not reset to its original position.
Is this something that the Lightroom 4 team is aware of?
One all the bugs are fixed I look forward to its release! Your hard work on this software is appreciated!
Best, Pam

The vertical and horizontal sliders are behaving more like the distortion slider.
When sliding left or right they are pulling from the center, rather than the right or left end.
Well, they *are* distortion sliders (sort of), leaving the very center of the photo unchanged. This has not changed from LR3. I can see no bug there. Also keep in mind that the visual effect is very different from wide angle photos to tele photos. Photos made with a tele lens are more or less just changed in the aspect ratio, and not so much distorted like wide angle photos.
Also, with the scale slider....If I scale down it shifts to the right.
This can happen if you used the horizontal slider before, combined with "Constrain Crop" - because the usable part of the photo shifts to one side or another. In the same way, scaling will shift up/down if one used the vertical slider before. This is perfectly normal. Hint: Try the vertical and horizontal sliders independently, with scaling set to 50 (minimum) and "Constrain Crop" *OFF* to see what they do with the photo - that made it a lot clearer to me how they work.
when I reset all the sliders to zero. The image doe not reset to its original position.
Also normal, because if you reset the manual corrections after working with "Constrain Crop" enabled, only the manual corrections themselves are reset, leaving the crop&straighten tool at some "funny" settings. Go to crop&straighten and reset it, too.
In conclusion, I see no bugs here. I also fiddled with the various manual sliders, and could not see any behaviour that was different to LR3, which has no bugs in this respect as far as I know...
P.S. I am not sure if I quoted the last question correctly or not. I assume these two sentences belong together?

Lens Correction in Lightroom 3 and Photoshop CS4

I just upgraded to Lightroom 3 and make use of the lens correction feature in the develop module. After doing all my
adjustments in develop I click ctrl-E to take the photo into Photoshop so I can tweak Levels. I noticed that the lens correction adjustments do not seem to be recognized by CS4 when the photo opens up.
Do I have to upgrade to CS5 to get the lens correction adjustments in LR3 recognized or am I doing something wrong. Thanks

I am using Lightroom 3.4, x64, and Photoshop CS5 (12.0.3 x64) on Win 7 OS.
I might add that, based upon my situation, limited knowledge & experience, I have a number of images ( aprox 200), taken with the same camera/lens combination, for which I want to take advantage of what seem to me the most useful features of each software package: in this case, the ability of Lightroom to apply common "development", first in lens correction and, later at the end, miscellaneous common settings; but, in the middle rotation & crop unique to each image.
Am I missing something, for I would think my situation not uncommon?

Auto lens correction for iPhone4

LR3.3 Auto Lens Correction correctly identifies my Nikon lens in NEF files, but can't automatically identify and apply correction to my iPhone4 JPG files. I can manually select Make/Model/Profile for the iPhone4 and apply. Not a big deal, but: user error or by design? I import straight from the phone using LR import. Camera make and model appear in the EXIF data. thx

Likely by design. As I recall, the iPhone 4 does not contain EXIF camera model metadata that distinguishes it from earlier iPhone models (e.g., the Make = Apple, the model = iPhone).
