Chromatic Aberration Removal in LR4 is terrible

I used a manual fixed focal length penatx lens on my Canon 40D and it shows chromatic aerration in the raw file. In LR4 all you can do is check the option to remove chromatic aberration. LR4 did an awful job making it even worse. See before and after image below. The chromatic aberration should have manual controls to adjust it to one's liking. Red/Cyan and Blue/Yellow sliders should be complemented by a Green/Magenta slider in the manual section. Now that would be an improvement on LR3. I loathe chromatic aberration which is unavoidable in many cases. More control over it's removal is a definite must. LR4 has gone backwards. I don't want to have to fiddle with profiles etc to fix this. Just put the controls that were in LR 3 back and add a green/magenta slider please.

I'll try the moire brush as suggested.
I am trying to emphasise the point that the software should be moving forward. That means new tools or upgrades should avoid adding artifacts as much as possible and certainly upgrades to existing tools should not perform worse than the original tool. I have found an example here where it does with chromatic aberration removal where an artifact is formed.
It's interesting that some of the commentary above almost suggests that chromatic aberration removal should be an adjustment brush. The user could then isolate the edges that he/she wants to remove the coloured fringes from. Then there should be the ability to choose which colour shifts are required red/cyan, blue/yellow, or green/magenta.
It looks like the current tool may improve some edges while making others worse. If checking the choice of automatic aberration correction doesn't work - then one has to go to another external editor to fix the problem - not the most satisfactory result of an upgrade. I like the suggestion in another thread of having both the option of auto and manual control options - much like exposure control. Photographers like manual control of image enhancements.
I have chosen to take pictures that have extreme aberrations to test the robustness of the tool. I have shot pictures with high contrast lighting, with older cheaper glass, and with the aperture wide open. I'll try to get some pictures to Eric as mentioned above.

  • Problems With Chromatic Aberration Removal

    I've noticed a problem with the chromatic aberration removal tool in LR4 beta; it seems to make CA significantly worse in some images.  I've attached two versions of the same photo of the moon, one with the CA removal turned on and the other with it off.  There is slight chromatic aberration with CA removal turned off.  When it is turned on, there is an obvious purple cast to the left edge of the moon.  I'd be happy to email the NEF to someone at Adobe, but I'm not sure who to send it to.

    Same for you ?

    I had unchecked Detail to see more precisely the effects of

    Should be easy to correct !

  • Would like some assistance with removing chromatic aberration from images . In using the slider tool only some of aberration is removed tried brushing in but not successful. After magnifying image 1005 i can still see some slight purple fringing .

    Can anyone assist me in using chromatic aberration tools in removing purple fringing completely from images?  I have had limited success in using the slider , but in zooming in at 100% I can still see slight purple fringing in image . i tried brushing in but that did not seem to remove purple fringing completely.

  • Lr 5 Remove Chromatic Aberration

    Hi,
    I've noticed the following with Lr 5 "Remove Chromatic Aberration": it's not only color aberration that disapears (e.g. Red) but all Red transition edges (from highlights to shadows) of the same hue that change to Grey (using either process).
    Am I doing something wrong? Have anybody noticed the same? With Lr 2 I have never noticed this situation: when elimination chromatic aberration (Red / Blue | Cyan / Yellow) and chosing Highlights or All, it was only the aberration that goes off. Can anybody help with this?

    Here's some screen shots with the problem (is defring) but if I don't change the hue and amount I won't have the aberration corrected.
    Camera: Canon 5DMarkII
    Lens: Canon 24-70mm f2.8
    file type: RAW
    OS: OS X Mavericks
    Image 001: no correction
    Image 002: corrected (as you can see in CA amount and hue sliders)
    Image 003: problem (man's face in shadows / highlights transition)
    Image 004: problem enlarged

  • The chromatic aberration checkbox that should be under lens corrections is missing

    The chromatic aberration check box that should be present under lens corrections is missing from my LR4 program, can anyone tell me what the problem is and how to get it back

    What version of LR4 are you using? There was a change made to the CA removal process in LR4.1, and the "Remove Chromatic Aberration" check box is now under the "Color" tab of the Lens Correction panel.

  • New Chromatic Aberration tools kills old settings.

    I've just recently found that new chromatic aberration tools kills settings for old chromatic aberration tools.
    Lets say I have a PV2010 photo with adjusted sliders for chromatic aberration reduction and selected defringe "all edges".
    Now I'm importing this photo to LR 4.1.
    Note: I'm not updating process version!
    Photo is automatically updated by Lightroom to new CA controls (note it still PV2010 photo).
    Well, I must say the the results are superb - they are the same as I was achieving with manual sliders, but now with only one click.
    But the problem is - Lightroom says that metadata have been changed, and I am writing back changes to XMP.
    But now XMP contains settings for new CA tools, but settings for old CA tools are LOST.
    So if I want to open this image in ACR 6.6, or send it to someone with older LR version I end up with completely resetted CA settings, because ACR 6.6 does not have new CA tools, and settings for old tools are killed by LR 4.1 - they are just removed from XMP.
    So I am loosing CA removal settings completely when opening image in earlier version of application.
    And I am NOT updating process version!
    Any comments on this?

    Here is screen shot in which you can see that even PV2010 photo has new CA tools and old ones are gone with their settings applied in LR3.
    I have tried to import CR2 files without any settings in the XMP into newly created empty catalog and have same result.
    When I am switching photo to PV2003 or PV2010 only new CA tools are available.
    And saving metadata to file kills old CA settings and writes settings for new tools (even for PV2010 photo) which previous versions does not understand.
    To my opinion this is very serious bug!
    Here is photoshop feedback message created 5 days ago: http://feedback.photoshop.com/photoshop_family/topics/lightroom_new_cromatic_aberration_to ols_kills_old_settings
    Looks like noone cares...
    Can someone at least say do I am the only person having this issue, or you can see this behaviour too.

  • Chromatic Aberrations and ACR

    I've read that Adobe Camera Raw (ACR) does a very good job of removing chromatic aberration artifacts.
    I do believe that, but what specifically in ACR is the tools / sliders that will do this magic ?

    It is great and a big time saver. Open a CR image in Camera Raw.  On the right just below the histogram are 10 icons with a lens being the 6th from the left.  Click on it, choose the Profile TAB, Select Enable Lens Profile Corrections, below in the Lens Profile select your Camera Make and if you are lucky your lens will be selectable in the Model pull down below.  IF not Click on the manual tab and do it the old way.  Also under the manual tab are some new geometric transforms that are sometimes useful at the Raw level.  Enjoy!

  • Auto-optimize chromatic aberration settings

    This is actually pretty simple to implement, has an obvious interface, and would be very handy.
    Add a dropper/crosshairs type tool to the CA module. When touched to the image it will fiddle with the CA settings until the fringing in that area is minimized. This could converge very quickly and accurately in an area like a backlit edge. If it doesn't converge, no big deal, do nothing and let the user try another point.

    Yes, and I think version 1 had it too.  The high-end cameras adjust in-camera too when producing jpegs.
    There's a lot of talk about proprietary lens tables and encrypted raw files on the internet, but I'm almost certain that these are not required.  If I can remove aberration by adjusting a couple of sliders and the alt/option key at 400% with a squint, without any lens tables, then it must be possible to do this automatically in software by measuring the green/magenta or yellow/blue levels in an image (or part of an image).
    Of course, the proof of the pudding would be in how Nikon cameras and Capture NX deals with non-nikon lenses, like Sigma, Tamron, and Tokina.  Do they get corrected too?
    There seems to be a trend at Nikon of producing cheaper lenses with quite a bit of lateral chromatic aberration.  It makes good business sense to save money on materials if the effect is easily (and cheaply) fixed in post-processing (as long as the aberration can be removed satisfactorily).  So the problem isn't going to go away; it may even get worse.

  • How can I repair chromatic aberrations in PSE?

    Hello,
    how can I please repair chromatic aberrations (the edges around are red, green or violet colored, this might not be) of my Fujifilm Finepix A500, 5,1 MP? I have Photoshop Elements 8 and I can not find a button to remove the aberrations. Can you please tell it step by step. I have not so much experience with PSE 8. You can write to me in English, German or Czech language. Thank you in advance.
    Sincerely
    Lesnivila

    Lesnivila,
    I some cases you might be able to remove the aberration with a Hue/Saturation adjustment layer. In this example, in the H/S saturation dialog box I selected red from the list and moved the Saturation slider all the way left. This desaturated most of the picture but I then filled the layer with black to restore the original.  Then I activated the Paint tool and painted with white over the red portion to restore the desaturation.
    I only painted the red on the sweater along the left portion of the table leg so that you can compare it to right portion.
    Note:  If you paint too far, for example onto the table leg, then undo it by painting with black to restore the original. If you initially set the foreground/background colors to their default black/white values, you can type "X" to toggle between black and white while painting.

  • Correcting chromatic aberration

    Hello all
    Why is there no option to correct chromatic aberration in the RAW procedure?
    Nikon Capture NX2 can do that easily. The correction algorithm looks very good there.
    I love the Aperture interface but finally what counts is simply image quality.
    Thanks

    Clearly this is not a question.
    Perhaps consider using batch CNX and save out tif and use Aperture as an alternative workflow.
    CNX can remove CA on most Nikkor lenses because its their own proprietary format (nef) with their own lens database and with their own bodies, and their own software. You're not really surprised are you?
    Maybe the next version of Aperture will have some CA removal capabilities... There is a suggestion submittal for Aperture.

  • CS5 Chromatic aberration sliders missing

    CS5 camera raw, under lens correction tab, profile, no chromatic aberration slider. Under the manual tab, same thing. Do I need to download an update?
    Thanks,
    Vince

    Nope.  The controls have been removed on purpose in Camera Raw 6.7 and they're not coming back.
    Adobe thinks their automatic CA removal is better, even though examples have been shown where it's not.
    See also:  http://forums.adobe.com/message/4397207
    You are forgiven for thinking that every new version should be made more capable than its predecessor and make better quality images.   Apparently Adobe feels other factors (ease of use?) trump this.
    If you don't need new camera support it's possible you can revert your Camera Raw plug-in to version 6.6, which still has the controls.  It gets a bit geeky, but I can advise you further how to do that if you'd like.
    -Noel
    P.S., It's easy to show that the newer method doesn't always work as well.  Note this Canon 10-22 image including the moon near the upper-left corner as opened with Camera Raw 6.6 vs. 6.7.

  • Lr and NEF Chromatic Aberration

    Dear All,
    The more I look at (D700) NEFs in Lr, the more I think Lr does not do justice to them (note that I do not blame Adobe for this). Indeed, if I look at Lr's rendition of NEFs compared to the in-camera generated JPEGs, I see chromatic aberrations which are not present in the JPEG. For instance compare
    with
    Clearly, the top image exhibits much less chromatic aberration than the second. Now, the top image is the JPEG and the bottom one is the NEF. Clearly, Nikon's on-board chip knows more about rendering the raw image than Lr does. Anyone else seen this effect ?
    With the introduction of camera profiles in V2.4, Lr made a step in the right direction. Now the question is: When will Lr be able to do at least as well as Nikon's on-bord chips when it comes to chromatic aberration ? Couldn't Adobe "buy" Nikon's "secret" and get Lr up to top speed ?
    Thanks for your time and input, folks.

    Jepoma

    Sorry, but the camera generated jpg includes all of Nikon's in-camera processing.  There is no reason why a nef in LR should duplicate it exactly.  Since Nikon is perhaps the hardest core about making certain information proprietary, you are comparing apples and oranges, or more appropriately a raw apple to an apple pie made with a secret recipe.  From my perspective, LR will never do "as well" as the on board chip because you aren't seeing the results of the onboard chip anyway but rather the processed data from that chip.  Actually, the LR image is likely closer to the unprocessed data than the jpg. Personally, I don't like Nikon's in-camera processing (and have never been comfortable with the detail I am losing with Nikon jpgs), so I shoot exclusively raw and am happy to do all the adjustment in LR.
    As far as Adobe buying "the secrets" from Nikon, I just think that is a bit naive.  That assumes that Adobe is the stumbling block, when the reality is Nikon has pushed to keep things propietary and sells its own (lousy) software to take advantage of the propietary aspects.  BTW, of course you are blaming Adobe - LR is not a living being, it is a piece of software designed by the people at Adobe.  If it doesn't do what you want and you are comparing it unfavorably to the Nikon straight-from-camera jpg, you would appear to be attributing a deficiency to someone. Based upon the rest of the post that certainly would appear to be the producers of LR....

  • Edit in photoshop loses chromatic aberration corrections

    Hi
    I have a problem I have not noticed before... when I do a chromatic aberration correction in Lightroom, then do "Edit in Photoshop",  it opens in PS but the chromatic aberration is still there, uncorrected. It seems to be applying other corrections okay, just not the CA correction.
    If I export the image as a tiff, then open it in PS, the chromatic aberration correction looks good. See the images below.
    I have been using Lightroom for years but not in the last year. I don't have the memory I used to have so I keep thinking I am just doing something wrong. Can anyone help?
    Thanks,
    Steve

    Mitch,
    I have seen the same when working with Adobe photo editors and in my case it turned out there were multiple copies of the image, one flattened and one with the layers. I need to nail this one down so I will get on this it evening when I get some time. In the mean time, check and see if there is another copy with the layers intact.

  • Is there a chromatic aberration or purple fringing tool in PSE 10?

    The subject line basically says it all.  The chromatic aberration tool in Aperture doesn't do much for me.  Is there one in PSE 10?  Thank you.

    Well, PSE's implementation of ACR can help correct chromatic aberration somewhat.  Here's the original image from somegirl's web site:

    Not great, but better than I expected.
