Just downloaded a trial version of NX2. The axial color aberration feature is very handy for certain images. Have not been able to use the Chromatic Aberration tool in Develop to even come close to doing the same thing. Defringe options do not match the NX2 solution. Am I missing somthing in LR?
Thanks for any help . .
jrs40 had this to say:
In 7 hours, no one has any response? Adobe, are you there?
This is not an Adobe official support forum. This is for user of LR,
helping other users of LR.
Since I don't use NX2, I can't help you.
Jack, I don't think you're missing anything. Lr also does not have NX2's automatic lateral chromatic aberration correction feature. Seems like Adobe has not given CA the priority it deserves. In fact, I wonder if Adobe give Lr the priority it deserves. I'll wait to see Lr 3.0 released to make a statement on this, but for now it could be more promising. Too bad NX2 has that poor user interface and no DAM component worth talking about ...
I'd suggest you make a feature request in the dedicated forum. I'd second it without problem.
Thanks very much for the response. It seems as though this is one area where LR is lacking. Have just tried DxO and it seems to work as well as NX2 in this regard. It looks like DxO will be a solution for now, as NX2 isn't real friendly. In any case, I'll add a feature request . . . again, thanks for the time.
We've had this discussion many many times before in the previous update/beta cycles and the Adobe folks are very aware that we want this. Some caveats: DxO takes the approach of measuring every body/lens combination and uses correction tables based on that. This means that lots of very common combinations of body/lens are unsupported and won't get corrected. It also means that there is no way Adobe is going to do the same thing as the parameter space is far too large. Nikon uses an automatic algorithm that they hold several patents on. Their algorithm works with any lens you put on a Nikon body. Which is exactly what you want. However, this also means that it might be hard for Adobe to implement it as they might have to license from Nikon.
I understand the differences between NX2/DxO and LR. The kind of aberrations we are having trouble with are those not corrected by Nikon's in-camera processing. This has only occurred using a 50mm G prime between f1.4 and f2.8. When stopped down, the aberrations are corrected by the camera. Nikon has stated this is somewhat a function of the lack of ED glass on the 50 f1.4G. In any case, no matter how Adobe can do this, it would be a welcome addition to improving the IQ output from LR. It sure would be nice not to have to complicate the workflow (although DxO does import directly to LR).
In any case, thanks for taking the time to respond.
Have you tried the LR 3 beta? I've noticed that the axial type color aberration (i.e. not the LCA I was talking about above) is much better controlled there than in LR 2. I don't know how they are doing it but it is significant.
I found this post looking for an answer to your question. In general, I really like using lightroom 3 for almost everything. I mostly use Canon, and was not as happy with the IQ of my Nikon d300. To see if some issues I had with my nikon was because of RAW conversion, I tried Nikon's View NX2. There were some notable improvements with the Nikon View NX software.
One of them was the "Axial Color Aberation" correction. Using my Rokinon 85mm f1.4 lens wide open resulted in some purple fringing in the transitions between black and white fabric on the sailor (see sample below). The Nikon software did a fantastic job of cleanup, Lightroom left something to be desired.
Of course ViewNX is pretty clunky, and 95% of my photo library is Canon so I'm happy to stick with LR for most everything. But I wish Adobe could replicate some of the controls of View NX.
Also, I would suggest that Nikon users that encounter undisrable results run their images through ViewNX software (it's free). In some cases, the results were notably better.

Did you try the new built-in correction in LR3? You might need to build the profile yourself but that is very easy ( i built several myself in an hour or so) There also might be one available for this lens on Adobe's lens profile downloader.

Yes I did use the profile I created for the Lightroom example. It did a great job regarding vignetting. And the Rokinon doesn't have a big problem with lateral CA's, that I think do get fixed with LR. I could be wrong (I often am!) but I don't think LR3 does a good job fixing the purple fringing thing. Also, I've tried turning on the defring all edges setting.
FYI: I've been experimenting with building lens profiles (all with no warranty) here: LENS PROFILES for various oddball lenses including the 85mm Rokinon example, as well as the 1000mm sigma apo, vivitar 100mm, etc etc.
The profile thing indeed only corrects for lateral fringes as it is designed now. Sometimes it also reduces axial fringes as a sideeffect so I was curious whether you tried. The defringe option is not very useful I would agree.

As you can see in the sample I uploaded, the difference is huge. Unless I'm missing something, LR isn't much help. Of course I only plan to use ViewNX in extreme cases like this because it's very inefficient and won't work for my Canon raw files of course. But it seems Adobe would be wise to impliment such a feature. And until they do, other photographers with similar issues should consider conversions with Nikon ViewNX 2.
BTW, I am very very happy with the new lens profile correction options of LR and PS!
