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.

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.

Can Photoshop CS3 Cut Chromatic Aberration (Purple Fringing) On Hi-Contrast Photos?

Some cameras such as the Panasonic FZ38 claim to eliminate chromatic aberration (purple fringing on high contrast pictures) from their lenses electronically.
If that is so, I would have thought that an app like PS CS3 (which has far more computing power) might be able to do the same.
Can it do this simply and quickly? I am fairly sure it can be done manually by spending hours retouching . . . . but that's not what I want!

sorry should have read open with camera raw

Chromatic Aberration - Purple Fringing

I've tried trawling the web and the Apple help for this but to no avail. I have a few random photos trying out new lenses which are coming up with purple fringing. Using other image editors I've been able to get rid of it, but the CA tool in Aperture 3 doesn't have purple - I'm sure you could make it from Red/Cyan and Blue/Yellow but not with just two sliders so I've been unable to get rid of it without resorting to exporting or lots of different desaturating tips and tricks. I found the halo adjustment brush but that seems burn the image while it removes the halo, so all in all I'm not having much luck.
Has anyone found a good process for removing purple fringing in Aperture 3? If so I'll pay good points for help.
Thanks all, James

Hi Kirby no I don't see the same in RAW shots with the same lens/body combo. It may be that Aperture's RAW converter is doing a great job and removing the CA before I can see it, or it may be that it was just the light / f-stop / shutter speed that day which contrived to give such obvious fringing around the blond hair of my son. I'll post some pics tonight to show you what the jpeg looks like, but I've been unable to find any in my RAW files.
I do convert my older RAW's to jpegs after I know I'm done editing / marking / scoring / printing them so I can't even go back to older photos and slide the RAW setting back to see if the fringing appears again. Sorry. If we ever see the sun again here in the UK I'll do some test shooting in the garden again and see if I can re-create it.
Thanks both. James

Canon HF R400 Chromatic Aberration and Blocking Zooming, Hard Time Focusing, LCD Display GUI

An otherwise nice cam for the price point especially end-of-the model year. I'm going to keep for primarily shooting youtube collectibles in a controlled environment of clamp lights with diffusers and either Auto White Balance or 'P' mode.
1. In my optical zoom tests (it's nice there's four speed options. I use number 3. The cam exhibits a lot of chromatic aberration which is purple, white ,or even green fringing around the subject matter. I shot of a telephone pole transformer box in bright light, the sky behind it, tree branches and snow on hedges in winter.
2. On a couple occasions when I zoomed in from about estimated 100-150yds the sky exhibited large blocky pixels for a second. But if I took it to an amusement park to shoot roller coasters I'd hold my breath for both reasons.
3. It has a hard time adjusting focus when zoomed in even from a close 1-6ft distance to record detail of collectibles or leaves on bushes etc.
4. The amount of display items on the LCD GUI is too much. Even the cheap Samsung F90 has a button to turn it off. Am I missing something. I read the 197pg PDF manual. Is there a way to turn off or at least reduce the number of items I don't need to see in order to actually shoot a video/picture? In still life tests. I had to take photos with the cam. Look at them. Then adjust. Then repeat. Just to see the composition. Kind of like in the day when pro photographers would take Polaroids prior to the film shot.
Note: If I'm allow to post youtube links or at least the titles of the videos to demonstrate in the near future when I upload examples of the Likes and Dislikes of my purchase I'd like to know from a Canon moderator (thanx in advance).

Hi ElectroT2!
Thanks for posting.
Chromatic aberration is not always something that can be completely eliminated. It most often appears when shooting a subject in the foreground that highly contrasts with the background Chromatic aberration is caused by a lens having a different refractive index for different wavelengths of light. Because each hue in the spectrum is not focused at a single point, colored halos or fringing appears. There are two types of chromatic aberration: longitudinal, where different wavelengths are focused at different distances from the lens, and lateral, where different wavelengths are focused at different positions on the focal plane.
Are you zooming optically or digitally when you see the "blockiness" in the image? If digital zoom is being used, it would explain why you see it. Digital zoom appears as the light blue area of the zoom bar. When you zoom digitally, the image is basically cropped and expanded more and more as you zoom. Because of this, the image quality will deteriorate the more you zoom in. You can select the type of zoom used in the settings menu under [Zoom Type].
Autofocus may not work well on the following subjects:
- Reflective surfaces
- Subjects with low contrast or without vertical lines
- Fast moving subjects
- Through wet windows
- Night scenes
You can always adjust the focus manually by selecting [ Focus] in the menu. You can then touch a subject that appears inside the frame, then touch and hold to adjust focus. When it is focused where you want it, then touch [ X ] to lock the focus. Something that may help you is when you are focusing manually, you can touch inside the frame to automatically focus on that spot to help you with the adjustment process.
As for the onscreen displays you are describing, they cannot be disabled so that only the subject appears on the LCD. You can, however, keep them from being displayed when the camcorder is connected to an external monitor. The setting is in the menu under the tab. It is called [Output Onscreen Displays].

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.

Chromatic aberration being introduced to RAW file by PS CS3

I have been working on some old photos (Canon 10D RAW files) and when I open the files in Photoshop I find that the file has severe chromatic aberration (introduced upon opening). While in ACR, the file is fine (no CA) but when it opens in PS there are significant green and red shifts (unfixable using the lens correction filter). This happens regardless of whether I open the file as a smart object, a 16 bit or 8 bit file. I have recently loaded OSX 10.5.1, and the PS version is 10.0.1. Has anyone else had this problem?

>While in ACR, the file is fine (no CA)
You may need to zoom into the corners of the image to 200-400% to see and correct CA as well as other fringing. The Lens correction DOES produce reduced or eliminated defringing if you properly use it. If you have a question, post the raw file.

Zoom does not reflect Chromatic Aberration in Develop

Hello
Have anyone noticed that in LR 1.0 (last build) the chromatic aberration correction shows up correctly if image is zoomed (for precise correction) but remains the same (not corrected) if the "fit" zoom is restored?
I corrected some .ORF (Olympus) RAW and found that if zoomed the correction (after playing with CA cursors) is ok (no more visible red/green fringe) but restoring the default zoom to see the full image doesn't show the corrections made. And the aberration is very strong so is visible even at "fit" zoom.
Does the Develop module not resample/redraw the image using a preview?
I think can be misleading to correct CA and not see changes reflected at all zooming.

Great.
These changes aren't viewable in the Develop module, except at 1:1. Gee, real helpful for 24 megapixel images... viewing at 1:1 that is. Unless, of course, I have a 42" high-quality LCD that, oh, doesn't exist yet.
And the Library module will probably just show the image with banding/JPEG macroblocking, so, no use there.
So, looks like the only option to view your CA/noise/sharpening-adjusted image fitted on your screen in high quality is to first EXPORT the file then VIEW in a viewer OTHER than LR.
Fascinating, how LR is such a wonderful image EDITOR, but is worse than just about every other piece of software out there for VIEWING.
Sorry, but even hyperbole doesn't suffice here. It's really just shocking that LR is the crappiest image *viewer* I've seen to date.
Actually, more shocking to me is that it seems that people *don't even care* about LR's sub-par viewing capabilities. Save for all my posts and one corroborating post by Andrew Rodney & another one by someone I can't remember (apologies!) -- no one has complained about the ridiculously horrid image quality when viewing images outside of the 'Develop' module. I mean, for a program that's all about 'aesthetics' and 'focusing on the image' (lights out mode, etc.), why show me a sub-par view of my images? Aren't my images the most important part of the whole picture??
And what's with all these optimizations for speed? Cutting corners here and there for speed...? On my 5400RPM hard drive MacBook Pro (ok, fine, Core 2 Duo w/ 2 GB of RAM), LR is *blazing* fast and I work with 120MB 16-bit film scans and I NEVER find myself sitting around for LR to perform a calculation, etc. It's *fast enough*... now how about putting some emphasis on *quality* back into the program rather than crippling the program so it runs faster (or not, if you have a decent machine anyway)?
Or how about at least giving us the *option* to enable purportedly 'high-end' features like, uh, viewing an image in full quality when presenting a slideshow to friends, or, *gasp*, PAYING CLIENTS...!!
Gosh I love Lightroom, and have mad respect for the developers... they are brilliant, intelligent, revolutionizing everything. But, man, sometimes these fundamental omissions, and lack of their recognition by the community at large, drive me insane!
Many apologies for the rant, since I know some people out there would like to bite my head off for being so caustic :-P

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.

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.

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.

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.

Chromatic Aberration Gone

I don't know exactly at what point this happened, perhaps with the 4.1 update, but the Chromatic Aberration check box has disappeared from Lens Corrections panel. It isn't where it was a while back under the Profile tab; nor are the old fringe tools available under the Manual tab; the Defringe pup-up menu is also gone. What gives?
I helped a friend upgrade from Lightroom 3 to 4 yesterday and found the same issues on here computer.
What gives?

Thanks, guys. I finally figured it out after some more tinkering. But the infor is not, unfortunately, in Scott Kelby's Lightroom 4 book, which was published before the change. If you can point me to any tutorials for the new version of the Defringe panel I'd appreciate it.

No chromatic aberration tool?

i shoot primarily wide angle, so i'm often dealing with CA. by not having this corrective tool as part of the RAW workflow (like in Adobe Camera Raw), i think i'll be locked out of using aperture all together. because, unlike with other features i wish aperture had - layers, masks, etc. - there is no workaround (export to photoshop).
does anyone know if this tool there and i just can't find it? or is there a workaround that i don't know about? because overall, i very much like aperture so far, and want to be able to use it. it would be a shame if this one small but important omission kept me from using what otherwise seems like a great program.
powerbook 1.67 Mac OS X (10.4.3)

thanks, just realized that cs2 has a chromatic aberration tool as a filter; it seems much cruder than the one built into ACR, but it will do the trick and keep me working in aperture.

Better chromatic aberration repair than ACR? Plugin?

I've suddenly (and sadly) become wise to the existence of chromatic aberration in my images. I'm finding that it's different from image to image - undoubtedly due to different lenses, zoom setting, etc.
I've been using ACR's chromatic aberration fix to generally good effect, but since it's different from image to image, it's not possible to just save settings as a template to use with every image. It's not a LOT of work to tweak each image, but I was wondering whether there was any "miracle" CA-fixing plugin out there that I should know about. Similar to how Noise Ninja seems to do a better job with noise than Photoshop's built-in tools.
Any recommendations?

It's expensive, but works wonderfully.
