Try increasing the Color Noise Reduction sliders or turning on the Defringe option.
I see no difference, except that the camera RAW image should really be sharpened a little. Where do you see colored spots in that image?
to Eric: by using CNR or Defringe you can reduce the effect but you cannot mremove it completely - to look like on original JPEC or Capture NX. By the way, i turned off all correction in NX but no color spots appeared
to Jao: try to zoom the picture in - spots can be easily seen at 200% or more
Ah, I figured out how to zoom. You can only zoom in the page with three images otherwise it yells at you in Russian if you try to zoom.
Anyway, that's funny. Some of the dots are blue and red (and orange and pink). I assume they should be black or gray? I don't think color noise reduction or fringe correction will help much here although upping chroma reduction might help some. This is a very curious effect and must be caused by the demosaic where some of the dots are not precisely aligned with the pixels and you get partial coverage by the Bayer mosaic, causing ACR to think the dot is another color then neutral. Weird!
Can you please post the raw file? Thanks. Or email directly to firstname.lastname@example.org
Eric, I have sent the file via 'yousendit' to your email. Also it can be downloaded from here
but I am afraid the download speed will not be fast
Thanks, I've got the file now.
Just an idea...
What if Nikon stores lens type in RAW file and then Capture NX (or internal camera processor) uses proprietary calibration information when developing?
>Capture NX (or internal camera processor) uses proprietary calibration information when developing?
the camera and capture NX do an automatic CA correction by a simple live fit algorithm (why can't ACR/LR do this? ;-) ) and they do fringe correction by default, so yes, there is an automatic correction but it is not related to the proprietary information. It works for every lens that you can take an image with with your camera.
> why can't ACR/LR do this?
It is bad enough that ACR makes these nonsensical automatic exposure adjustments, but that can be encountered if one knows about it. The last thing I need is automatic CA correction.
I am working with raw data just
b in order to avoid automatisms.
This is the SINGLE point of using raw data.
(Beside, there is no CA involved in this case.)
I also don't think that CA is involved. Capture NX indeed does automatic CA adjustment but the effect is not visible if CA is off. Not sure about defringe, however - it looks like NX applies it by default because there are no controls in Camera Settings.
Of course, RAW processor should avoid automatisms but in this case I could not remove the effect with any combination of ACR parameters
I'd love automatic CA correction! But we can all be happy if it's selectable in preferences, just like 'auto tone adjustments'.
It frustrates me that I need to do CA on almost every shot I take, when it can't be that difficult for a computer to do the same job.
just to follow up...
Eric, did you manage to find out anything from the raw file?
ioutkine, I'm still looking into it. Thanks for providing the file.
I see that ACR 5.3 release candidate is available. Does anybody know if the issue discussed in this topic has been fixed in 5.3?
No changes were made in this regard for 5.3.
to Eric or any one from ACR team.
Has anybody had a chance to sort out the problem?
Due to the bug all Nikon D90 users cannot benefit from Raw processing using Photoshop. This is very frustrating fact...
I'm not from the ACR team. However I downloaded your DSC_0566.NEF raw file.
I opened it in ACR 5.3. The image is overexposed by about 4/10 of a stop and consequently has numerous clipped highlights. I moved the exposure slider to -0.40 and the Recovery slider to 28. I left all other settings at whatever the Auto adjustment left them: temperature 4850; Tint -7; Fill Light 0; Brightness 0; Contrast +19; Clarity 0; Vibrance 0; and Saturation 0.
I see no color artifacts like those clearly shown on your posted crops. Same results (no color artifacts) with Adobe Standard, Camera Standard, Camera Landscape, Camera Neutral, Camera Vivid, etc.
Default Sharpening settings (25; 1.0; 25; without any additional sharpening. Noise Reduction: Luminance 0, Color 25. No Chromatic Aberration correction, Defringe off, no Vignetting correction.
Screen shot of 200% view in ACR 5.3 preview box.
the colored spots appear with lowered color noise reduction.
IMO this is a byproduct of the demosaicing algorythm.
>Due to the bug all Nikon D90 users cannot benefit from Raw processing using Photoshop. This is very frustrating fact...
That's just a tad hyperbole. I doubt any significant amount of Lightroom and D90 users notices this problem.
>the colored spots appear with lowered color noise reduction
Interesting. Thanks for pointing this out.
There are many arfitacts when processing D90 with current ACR. This example demonstrates just most visible one. Even though they are nearly not noticeable on whole picture, the fact that they are still there - does not add confidence.
To Ramon: I do see color spots on your picture. The problem is that other software (Nicon Capture NX) does not make any at all - having all correction off! Please refer to my first post.
I like Photoshop and don't really want to develop my RAW with other program and that's why I pointed out to the problem
Yes, I see the blue spots now. I had focused on the red ones. My bad.
(Sorry about my English)
I do have the same problem. I work with Lightroom 2.3 or with Camera Raw 5.3 and Photoshop. The D90 RAW-handling with LR and CR is very bad. When I compare with the Olympus ORF-File , difference is incredibly. Also when I do NEF&JPG together. JPG-Files are full of brightness, and the NEF-Files are sallow, have dark areas. Please open the NEF and look at the hair. The structure is completely washed out specially the darker areas.
I work all the time with RAW-Files in LR, CR and Photoshop. But now I cant do this with my new D90. Its frustrating. Is there no solution from Adobe? With Nikon ViewNX and so on, it works well. But my standard is Adobe LR and PS!!!
I also work with Nikon coolscan v. This NEF-Files are brilliant to work around in LR and PS. Its really a problem with the D90 and Camera Raw.
Please help me!

try the camera matching profiles. They will make your nef files look like the jpegs as long as you don't use ADL on your camera. See this article and hundreds of others around the web. If you use ADL, turn it off, the only thing it does is underexpose your RAW files.
Thanks a lot!! It looks good! I give a feedback after few tests in the next days, now it's very buisy...
to Jao van de Lagemaat :
Unfortunately setting camera matching profile cannot help to resolve the issue described in the first post. Currently there is no combination of ACR parameters that could eliminate the artifact. It looks like there is a bug(s) in ACR which has not been fixed yet.
Question to ACR team - do you agree that this is ACR problem? When are you going to look into it?
I already mentioned that neither jpeg nor picture produced by Nikon Capture NX have the artifact - it only appears if NEF file is processed by ACR
The issue will be addressed in a future update.
Any progress on this or ETA? I really would like to go directly from camera to LR/CS4...and not have to stop at Nikon software just to get the Chromatic Aberration processing.
Thanks for addressing and replying on this threat. It really helps the community when there is input from Adobe directly on issues like this.
Yes, there has been good progress on this, but unfortunately I do not have an ETA to give you. I can assure you the issue has not been forgotten, and will not be forgotten. The sample image provided earlier in this thread was very useful -- thanks.
I understand there is good progress on the problem. Maybe now you already have ETA, please can you tell us when the issue with D90 is expected to be fixed?
Unfortunately, I do not have an ETA for you. It will be in a future release, for sure. However, which release, and the date of that release, is not known at the moment. I understand that you are curious, and that this lack of real info is likely frustrating to you. All I can do is ask for you to be patient. It will come.
Yeah, it's really frustrating that such reputable company as Adobe cannot fix the bug reported more than half a year ago
It's been very long time since the issue was spotted. I am just
wondering if the problem has been fixed. In which version?
Yes, it was fixed in Camera Raw 5.7 (free update for CS4 users).
For CS5 customers, yes, it is also fixed in Camera Raw 6.x.
