    Any possibility of returning CA slider ?

    Vit Novak Community Member

      Checked more raw files from Canon compact with acr 7.1. Yes, 10x zoom lens is of poor quality, but my hand made profile (tuned it with text editor, without profile editor) was able to deal with it succesfully. New automatic CA removal removed only a half of CA. Attaching result without CA removal, with profile and with automatic CA removal. Defringing was off in all cases

          For this image I would use auto CA + defringe, local defringe and noise reduction.

            Obviously.

             

            However, I wanted to show differences between automatic and profile based CA removal on that image

              Ouch.  That's the first I've seen the image analysis-based version work that badly.

               

              Seeing the old code go away I have been a bit scared I'd come across an image that throws it off, but so far I hadn't.  The fear had started to subside, as my results have so far been better than before, but your image scares me afresh.

               

              Perhaps putting up the raw file for the Adobe people to work with might entice them to tune up the algorithm for a future release?

                I can believe that for most people, results will be better than before, because several profiles I tried were not perfect so to say. However, math model of profiles was good enough to cope even with quite severe cases like this. I didn't make very extensive tests so far, it was just 4th photo from the bunch of photos from my last vacation

                 

                Of curse, I can post the raw and the lens profile if someone wants it.

                    Have you sent this to Eric Chan with an explanation of Auto-CA not working for the extreme edges?  madmanchan2000@yahoo.com  He’s really the only one who can fix things with the Auto CA. 

                     

                    It is interesting that the remaining fringes against the sky can be fixed with the manual defringing relatively easily, but the edges of the archways do not defringe properly even with the amount sliders maxed out at 20 unless the color ranges are also significantly widened.

                      Well, Eric is reading these posts from time to time, so I hope he will read it and decide what to do

                       

                      However, there is more. This one is from Panasonic LX5. Also a compact camera, but lens is quite good and CA is corrected in-camera (including raw I suppose - lens can't be that good anyway). However, defringing isn't corrected. So I tried new defringe tool (global only). Check the photo

                       

                      Defringe.jpg

                       

                      When I moved purple hue slider too far to the left to get the whole hue range of fringes, sky suddenly bacame defringed

                       

                      I have a feeling that it should possible to improve this defringing algorithm, because fringes are over the dark sides of the edges and not over the brigh sides like sky.

                       

                      Hope I won't get the advice to use more NR again

                        In the past Eric has requested people send him sample files, directly, along with a short explanation of what you’re seeing.  I have sent more than one since Auto CA was introduced.  If you like, I can send your files to him, in case he doesn’t happen upon this thread, himself.  I would probably link back to it, as a way to source the files.

                         

                        Regarding your new example, yes, that is what I saw when trying to fix your earlier image.  Fringes extend from either side of an edge, so both the trees and the sky are probably having their color neutralized, you just can’t see it because the trees are already dark and relatively neutral.  I think the color-range slider is there to choose the areas to start neutralizing from—a Photoshop select-color-range-globally and the strength slider is the +/- fuzz amount out from the selected color.  Fringes typically fade into the surrounding color so there needs to be a way to select colors not entirely within the defringe-color range, but connected to an area of that color.

                          Yes, in my opinion, fringe color should be neutralized on the dark side of the edge, but not on the bright, or at least to much shorter distance. And amount of neutralizing should decrease with the distance. I'm not sure it's the case here, although I didn't make extensive tests

                            Yeah - I've had a few cases where the defringer works fine as is, but more cases where it bites too much non-fringe before biting enough fringe, in which case I have to resort to painstaking local application to remedy... - there's definitely room for algorithm improvement, in my opinion.

                              I’m not sure the manual defringer looks for luminance edges or at least not entirely.  My impression is that an “edge” is between the area you’ve defined in the defringe-color range and the areas outside of that, so if you include sky color in your fringe color range then you’ll get sky neutralized.

                                Perhaps you need to use more NR. 

                                 

                                With enough NR, the color fringing goes completely away.  To wit:

                                 

                                NR.jpg

                                 

                                In all seriousness, we have some disturbing things happening with Camera Raw 7.1...

                                 

                                They've tried to improve something that was already very good, and most importantly gave the user a great deal of control, with something that works better in some cases, and (as you've shown) MUCH worse in others.

                                 

                                I am all for simplifying things, but in this case, why not just leave the original controls (and algorithms) in place and add the new controls and algorithms as an option.  Maybe it could even be an either/or thing.

                                 

                                It's the combination of loss of both the CA correction controls and the Defringe Edges feature together that's made it work worse, in my opinion.  In one case user control has been taken away exposing shortcomings of the automatic operation, and in the other additional control has been added without obvious benefit.

                                  Using manual defringe, you can control the mask, so it won't cut into the sky, or whatever - you have to paint carefully...

                                   

                                  But yes, purple against blue sky is more removable (globally) than blue fringe against blue sky...

                                    Yes, using manual defringe can work I suppose, although my first attempts were not very sucessfull.

                                     

                                    However, I was doing it on some photos even before local defringe existed, brushing those parts precisely and using desaturate, correction of exposure and usually some color temperature change. Worked quite well, but it was VERY slow

                                     

                                    I hope Adobe is able to make something of similar effectivity, but not as time consuming as that method

                                      Was it a bare lens or there was anything between the lens and the subject?

                                        Good point.  There appears to be a car window in between the camera lens and the rainy scene, at least in the first example.

                                          I have no problem with asking a question for curiosity's sake, but it doesn't matter from a software perspective - if the old version could globally fix the radial color-fringing, and the new one can't without a twisted application of some of the features intended for other purposes, then the changes can be classified as:

                                            Re-reading this thread, and noting that the only feedback from Adobe to arguably the most brilliant user of Camera Raw anywhere to be found is complete ignorance that a bona fide problem has been exposed and the offer of a basic suggestion to try to use some of the other features, I'm a bit disappointed.  Yes, I realize we've just been through a weekend, but Vit's thread was here all day Friday.

                                             

                                            Can we please hear from the Camera Raw architects here?

                                             

                                            Frankly I expect no less than either assurances we're either going to see a reinstatement of the old features that worked, or a tweaking of the new features until they work as well or better.  Just being quiet about this and hoping it will go away is not a valid option!

                                             

                                            What better feedback than this could you possibly hope to get from exposing the pre-release code to the public?

                                              Well, it's not like they don't have a life elsewhere...point of fact, Eric is traveling and Thomas is busy doing stuff. This is a user to user forum so it would be useful to keep that in mind and not demand an ACR engineer to engage here (such demands have a greater likelihood of driving them away dooode).

                                               

                                              Personally, I was able to fix the lateral and longitudinal CA using the auto CA and a touch of global Defringe and a touch of local Defringe and morie. The results are better than Vit's tuned lens profile. With a cheap lens whose more obvious defect seems to be the black lamps against blue sky, I really don't think this rises to mission critical (considering there are fixes one can do). The odds of bringing back the old CA adjustments and lens profiles are just about zero. And again, it's not like the guys don't have anything better to do.

                                               

                                              And while Vit is pretty good technically tweaking DNG profiles and hand tuning lens profiles, I don't think he ranks as "arguably the most brilliant user of Camera Raw anywhere to be found". ACR 7.1 is at RC status...I think you are gonna have to learn to live with the current functionality and learn how to use it. The old tuned profiles for CA are not gonna work–period.

                                              Since it's really primarily just this single area that looked less good with the globals and needed the locals, I still suspect something else is going on that interfered the auto CA fixing that area...I didn't see the same CA on the right side. The auto CA looks at all courners and edges...I'm not sure it looks at objects pre se...but I will say that in all my tests of the Auto CA and the new Defringe for longitudinal CA, I've rarely had to resort to local fixes like this image needed. So, I'm not sure calling ACR 7.1 "broken" is warranted...

                                               

                                              Vit, sorry bud, but I think you're gonna have to learn how to move on without the old functionality...

ACR 7.1 is at RC status...I think you are gonna have to learn to live with the current functionality and learn how to use it. The old tuned profiles for CA are not gonna work–period.

                                                 

                                                Since it's really primarily just this single area that looked less good with the globals and needed the locals, I still suspect something else is going on that interfered the auto CA fixing that area...I didn't see the same CA on the right side. The auto CA looks at all courners and edges...I'm not sure it looks at objects pre se...but I will say that in all my tests of the Auto CA and the new Defringe for longitudinal CA, I've rarely had to resort to local fixes like this image needed. So, I'm not sure calling ACR 7.1 "broken" is warranted...

                                                 

                                                Vit, sorry bud, but I think you're gonna have to learn how to move on without the old functionality...

                                                 

                                                Jeff, I have to say I'm not satisfied with your answer

                                                 

                                                I certainly don't claim I'm the most brilliant ACR user here and I don't claim that image couldn't be fixed with this version of ACR. I wanted to demonstrate that in this particular case profile based CA removal works better, that's all. So I didn't use other tools that would hide that fact. So I'm not sure that removing the feature, that worked very good, at least with good lens profile, is a good idea, unless there is some sound reason for this

                                                 

                                                It's however up to people from Adobe to decide what to do with it. I can still use old ACR version for this camera

                                                 

                                                I'm actually more concerned about new defringe feature that doesn't work the way I think it should be working. But I hope I'm wrong

                                                  The lamp is very easy to fix.  What do the arches in the building look like?

                                                    The CA-modeling seems to be failing near the left and right extremes in Vit’s example, not so much the lamps, those are easy to defringe, but the arches and other less stark edges.  I would vote for more work to be done on the modeling, to handle a case like this.  It’s possible that the small-sensor RAW is so noisy that the fringes are lost in the noise and cannot be detected very easily.

                                                      If I paint the local corrections of Defringe +10 and Moire + 15 into the arches, they're fine...I can get rid of any hint of color fringing in the whole raw image with the above settings...plus the global settings.

                                                        It worked fine for YOU who hand tuned a lens profile that didn't correct CA very well on its own...how many users in the ACR user base have ever done that? How many have even created a lens profile? How many actually use any sort of lens profiles or CA corrections?

                                                         

                                                        I don't really care about HOW I correct my images...I'm interested in the ability to do so. If the auto CA needs some help (and you have to admit you had to help the old lens profiles with hand tuned editing) with some defringe either global or local, so what? How many angels can dance on the head of a pin? If you can get what you want, does it matter?

                                                         

                                                        I'm not really too interested in extreme edge cases where auto CA doesn't work quite as well as hand tuned lens profiles as long as I can get my images to look the way I want them. I think your use case is weak and unlikely to get much traction...

                                                            I don't think defringe is a particularly satisfactory way to correct excess lateral CA, as it only applies to high-contrast edges (as far as I know). One of the problems caused by lateral CA is a general softening of the image caused by misalignment of the different light frequencies away from the centre of the image, and defringe won't help with that.

                                                             

                                                            Personally, I haven't had a bad auto-correction with 6.7 yet, and I am very pleased with it, but I can see Vit's point of view, and I appreciate that it would be nice to have the option if it did fail.

                                                                I checked two photos with 400D in the meantime, and, interestingly, automatic CA correction was better than my profile (which is slightly corrected profile from Adobe) with those photos, although it was a kit lens, so it's not especially quality piece of glass either

                                                                 

                                                                So if automatic CA correction works quite well with this lens, I'm wondering why it isn't so succesfull with SX110. Is aberration in lens so severe? Is it because of more noise? Shorter focal distance? Or something else?

If I use manual CA correction, blue/yellow correction needed is considerably higher than for other lenses. Optimal manual setting for CA correction for this focal length is about -30 for red/cyan and about +40 for blue/yellow. Maybe I'm wrong, but it looks like ACR is trying to compensate only red/cyan, so it's the best it can get. Or something connected with this

Most profiles by Adobe contain also parameters of 2nd order (while it's possible to use even 4th and 6th order, according to the paper by Eric and his coworkers - I used them only for vignetting and distortion correction, like Adobe in other profiles) ... so this profile was actually simplified and not overtweaked

                                                                      Well, the portion of my post you quoted has nothing to do with whether or not the CA is or isn't "good enough" but has everything to do with YOUR expectations that the engineers should come running when you call.

At some point, I'm sure Eric will take a look at it. But he'll do so when he can find the time and at the moment, he is taking some well deserved time off...is that ok with you?

You know better than that. Eric does a real good job of spending time with users and addressing their concerns when he has time. You really should not take that for granted...which is what I read in your demands.

Also, there was manual CA correction introduced several years ago that also worked fine although required some more work. Now both options are gone and replaced with automatic CA correction, which fails here
