Community lens correction works for me

A few days ago lens correction profiles showed up for my D300 with both 16-85VR and 55-200VR lenses.  Brick wall testing indicates they seem to have nailed distortion/CA/vignetting, at least for focal length extremes.
So how do we know where these profiles originated, if for no other reason than to give credit?
Richard Southworth

I can think of one really good reason why a lens profile should be camera-specific for the best possible results:
Not every sensor responds the same to light coming in from various angles.  Microlenses, for example, are different from sensor to sensor.
So the vignetting profile for one camera might be a general improvement on another, but it may not produce specifically accurate results on that other camera.
You cannot oversimplify the problem and achieve perfection.

  • Lens correction profile for the Canon 18-135 STM lens in Lightroom 5 ?

    How or where can I get the lens correction profile for the Canon 18-135 STM lens in Lightroom 5 ? In effect he is not available in my list of correction lens so my lightroom is up to date apparently :/
    Thanks in advance for answer.

    There are two types of Lens profiles - raw and JPEG. It looks like you are trying to process a JPEG image and Adobe has only provided a raw lens profile for the 18-135mm IS STM lens.
    You have four options:
    1) Check for available lens profile using the Adobe Lens Profile Downloader. I checked and a JPEG lens profile is NOT available for the 18-135mm lens.
    2) Follow the procedure outlined by Steve Sprengel in this post:
    http://feedback.photoshop.com/photoshop_family/topics/lr_5_lens_profile_not_applied_for_jp g_captures_only_for_raw_captures
    More detailed instructions here for a Pentax lens example:
    http://www.pentaxforums.com/forums/post-processing-articles/176761-creating-adobe-lens-cor rection-profiles-jpgs-raw-ones.html
    This allows using the available raw lens profile with JPEG images. To my knowledge Canon DSLR cameras do not apply distortion correction to JPEG images, so the raw profile should work well. You can check this by shooting raw+JPEG and comparing the two images inside LR
    3) Create you own lens profile using the Adobe Lens Profile Creator. (A complicated process, but it can be done!).
    4) Start shooting in raw mode or raw + JPEG mode, which will allow you to extract the most benefit from LR's processing controls.

  • Where can I find lens correction profiles for EF 17-35 f/2.8L lens using ACR 6.2?

    Using Photoshop CS5 Extended on iMac 10.6.4.
    I'm  working with wedding photos shot by a friend but I cannot find lens  correction profiles for Canon EOS 20D or the EF 17-35 f/2.8L lens. When I  search online it simply says "No online profiles found". Is there a  download for older lens profiles? I checked & I'm using ACR 6.2. I don't have the camera so there's no  way to take test photos to create my own profile. But, shouldn't there  be a profile available; the camera isn't that old?

    Go to DXO Pro and download the 30 day trial. It works very well for lens/body correction, and unlike Adobe, DXO maintains data on the older cameras and lenses. Updates will always have those available. Adobe is a latecomer to this part of the correction process, so as Ian said, no call, no supplier? Out of luck.

    It's fair to note that DXO does not necessarily have a complete line of everything, like my Tamron 28 to 75 isn't available as a module. They do pay attention to demands, or lack therof,  that are not mainstream as well. But their offerings are excellent, and the tests, professional.

  • Lightroom 4 Lens Corrections Profile for the new AF-S Nikon 80-400mm f/4.5-5.6G ED VR

    When can we get a Lightroom 4 Lens Corrections Profile for the new AF-S Nikon 80-400mm f/4.5-5.6 G ED VR lens?

    Based on the past - probably next version. If not, then the one after that.
    PS - That is unofficial info, and may be wrong...

  • Lens correction profile for the Canon 18-135 STM lens?

    How or where can I get the lens correction profile for the new Canon STM lenses?

    I see that lens listed in the release notes for the final Lightroom 4.2 update that just came out a few hours ago, so it looks like the answer is to download the update.

  • Is there a lens correction profile for Nikon D3100 18-55mm?

    Is there a lens correction profile for Nikon D3100 18-55mm? I so don't know what I'm doing

    The only profile I could see is a profile for the 18 - 55 mm for the D300.
    As far as I know the sensor size is identical for the D3100 and D300, so you can use this this profile.
    If the profile is not installed in the list of your Lr, you have to download it. In order to download it you have to download and install the Adobe lens profile installer first.
    And before you can install the lens profile downloader, you need to download and install Adobe Air.
    These two programs are for free and can be downloaded from Adobe's website.
    Nothing is ever easy, is it?

  • Lens correction file for the Zeiss Touit 2.8/50M

    Could we get a lens correction file for the Zeiss Touit 2.8/50M inside Photoshop CC in the near future?

    Most probably, the slanting of the cup in the corner of the image is not created by distortion of the lens but by pointing the camera down.
    When the camera is not held level but pointed up or down, the sensor is not parallel with the vertical lines of the cup. This is the "Scheimpflug" phenomenon - google for this word and you'll get lots of results. The "Scheimpflug" phenomenon gets stronger towards the edges of the image.
    This is why architectural photographers use "view cameras" where you can adjust the angle of the film plane or the digital sensor plane so that it is parallel to the vertical lines of a building.
    You can adjust the slanting of the cup with the manual vertical slider in Lens Correction,  and you might have to adjust the horizontal slider as well. The trade off is that that now your image will be severely "keystoned" and that is probably not what you want.
    But you cannot blame the lens profile. The lens profile corrects only distortion by the lens., not distortion by the "Scheimpflug" principle.
    PS: A tilt-shift lens will also correct distortions of the "Scheimpflug" principle.

  • Does the lens correction profile for the Canon 24-70 eliminate all distortion?

    The new Camera Raw seems excellent in the Lens Correction...I will be photographing dancers and will have only 9 feet to work with. I would like to use the widest lens I can with lens correction. The question is whether this new program will flatten out the 24mm lens or if I should use the 35.
    Roger Minkow

    To add to Eric's great explanation, the corrections here are for barrel and pincushion distortion. That can be present in a lens of any focal length.
    What isn't corrected is the effect in wide angle lenses where there is spreading of the image of three dimensional objects away from the center of the field. It happens at any distance, not just close up. It is caused by the extreme angle of projection from the back of the lens to the flat film/sensor plane. Think of a straight on photo of a building that has equal size columns across the facade with a wide angle lens. The columns at either end of the image appear wider than the (same width) columns in the middle. Retrofocus design wide angle lenses help a little bit (the rear of the lens is further from the focal plane than in a standard wide angle), but the distortion is usually there.
    There is also distortion from being too close to the subject. Focal length doesn't really matter in that, except that longer lenses don't have the field of view to take in the close subject and can't usually focus that close. So we associate this distortion with wide angle lenses. This sort of distortion would be that where a person's nose in the middle of the frame looks very large and there is quick falloff in size to the eyes, ears, background. I think of this as more an issue of perspective, and this is controlled by camera placement, not by focal length or lens design.

  • Lens Correction Profile for Rokinon/Samyang 12mm F/2.8

    I am getting this lens for my Sony A7II. I cannot find the lens profile for this lens. Can someone tell me where I can get a lens profile for it? Thanks.

    Problem solved.  I just learned that in order to properly use this feature of LR, you need to be working from the RAW file.  I was working for a jpeg.  I imported he RAW file and LR provides a number of lens profile options to correct for distortion - most importantly the one I needed - Tokina.  

  • Photoshop CS6 No lens profiles (lens correction filter) for Canon 6D raw files

    LightRoom and Camera Raw have profiles for Lens Correction and all the current available lens are  in the list for the Canon 6D raw files. BUT the Filter/Lens Correction when in Photoshop CS6 only have 2 Tamron lens listed. Odd that there are lens profiles for the Canon 6D raw files  in Lightroom and Camera RAW but not CS6 Filter/Lens Correction.
    Camera RAW, LR and PS are up to date..... NOTE: I have a Canon 7D, G11 and 1D Mark II N and all their files work as expected. It's only RAW files created by the Canon 6D.
    Any suggestions.

    To the right of where it says Search Criteria, click the little three-bars-arrow icon and uncheck Match Sensor Size and it should find more.

  • Where do I find Lens Correction filters for old lenses - like the Pentax 28mm shift?

    Using different lenses for photographing buildings, I found that the lens correction filter options in Photoshop CS6 work GREAT. Simply brilliant for the the Sigma  EX 10-20mm 4.5-5.6 wide angle zoom.
    But where would I find af filter for corretcing my old SMC Pentax Shift 1:3.5 28 lens? And - if I find it - how will I install it in photoshop CS6?
    Regards
    Jens in Denmark

    You can download and install the Adobe Lens Profile Downloader and it looks like two downloadable profiles are available.

  • Lens correction works with my RAWs, but not my JPEGs?

    Hi all, if I check "Enable Profile Corrections" for any of my RAW files, Lightroom automatically identifies the Make/Model/Profile of my lens. However for my JPEG files (same camera, same lens) when I check "Enable Profile Corrections" it defaults to none/none/none, and my lens doesn't even show up in the dropdown menus if I try to select it manually.
    How can I get Lens Correction to work for JPEGs as it does for RAWs?

    Update, got it working, sweet! I'll post what I did below, hopefully useful to somebody...
    1) Probably the best thing would be to make my own Lens Profile -- http://labs.adobe.com/downloads/lensprofile_creator.html -- but I'm not quite ready for that now, I just wanted to make the built-in RAW profiles work for JPEG too.
    2) I located the RAW profiles I wanted available as JPEG profiles, in this folder:
    C:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0\[MyCamera]\
    3) In this folder:
    C:\Users\[USER]\AppData\Roaming\Adobe\CameraRaw\LensProfiles\
    4) I created the following subfolder:
    C:\Users\[USER]\AppData\Roaming\Adobe\CameraRaw\LensProfiles\1.0\[MyCamera]\
    5) I copied the RAW profile files from #2 above into this new folder.
    6) I set the files to not be "read-only"
    7) I opened those files into a text editor, and I performed a Find/Replace.
    From: <stCamera:CameraRawProfile>True
    To: <stCamera:CameraRawProfile>False
    (Note that there are multiple instances, so I performed a Find/Replace ALL.)
    8) I set the files back to "read-only" (probably not necessary)
    And now when I turn on Lens Correction for a JPEG, it works! And it seems like my camera isn't performing any lens corrections (such as vignetting) when saving JPEGs, so it's pertty good as-is. Though, per #1 above, probably the best solution would be to make my own Lens Profiles from scratch.
    Thanks to all & I hope this helps somebody...

  • I don't get the Lens Correction Profile for Sigma 10-20?

    I see several postings of people discussing the lens profile for the Sigma 10-20. As a proud 10-20 owner, that is the first profile I looked for in LR3, but in my (trial) copy I don't seem to have it - there's only the DC4.5, DC18-200, DG8, DG12-24, and the DG15.
    Where can I find the Sigma 10-20 lens correction profile that others are referring to?
    (Thanks!)

    That is confusing.... So I cannot see/use the Sigma 10-20 lens profile on any jpg picture ... ?!?
    Is there no Sigma profile for jpg available?
    Well....technically no.
    However, I found this approach limiting so I converted all the Sigma-generated raw profiles to JPEG profiles.  Yes, they might not be perfect, but they work better than nothing (actually, way better than nothing).
    Inside each profile lcp file, you'll find tags that look like this:
    <stCamera:CameraRawProfile>True</stCamera:CameraRawProfile>
    or this
    <stCamera:CameraRawProfile>False</stCamera:CameraRawProfile>
    The first is for raw files, the second for JPEGs.  There can be many such tags in each lcp file.
    What I did was copy all the Sigma-generated profiles and replace all those tags in the copies.  Voila!  JPEG profiles for Sigma lenses.

  • Lens correction profile for new Sigma 12-24 mark II

    Hi
    Sigma 12-24mm f4.5-f5.6 II has been out for a while. But i can not find a lens correction for it in lightroom. Does anyone know if there is such a profile ??

    Adobe does not announce release dates for new profiles. However, you can except that the next minor release upgrade after the release of the lens will bring the profile to LR.
