I was going to try out the Topaz file, but when I downloaded the trial zip file from their web site, my Norton popped up a warning saying it was an infected file (??). Not going to risk that one.

7D users: Best noise reduction for solid blue skies specifically?

In Adobe's tutorials about their new ACR they are very proud of their new noise management and I think it is justified because it is so much better than the previous version. It is their first update to RAW processing in several years. They say they totally rebuilt ACR. I usually notice a big difference when I reprosses an older photo.

They do have some information about it on their web site, but not a huge amount I agree. Certainly there have been many comments about the improved NR algorithms on these forums. Why don't you download a trial of LR3 and test it out?
Certainly CS5 is a huge improvement on the past.
Kind regards
Stephen

I don't have a 7d..but Noiseware set to reduce noise in Blue/Cyan only.. works pretty well for me. I like it a lot, since you can specify frequencies, and colors you wish to reduce noise in. You can also write Photoshop actions that maintain the settings you choose in each action, in the Pro version. My cameras are all noisier than the 7d and it almost totally eliminates blue sky noise if I chose it, even after darkening the sky in PP. They may still have a trial version.

Here's a crop of what I'm trying to get rid of (below). I want the sky to be just a smooth, solid blue instead of the muddled look it has.
Tried the Ninja trial last night and it actually made the effect worse (??). Downloaded Nik but haven't figured it out yet. It might be better.
Anyway - here's the crop:

NR and overall sharpening algorithms in LR 3 (now 3.2) are SIGNIFICANT. Depending on your image you can almost eliminate any post export processing from RAW once converted to JPEG in both Noise and Sharpening categories.

Is this typically how blue skies look in a 7D shot?
I know you mean well but please do not embed my images into the forum. Thanks for respecting that.

I probably won't get a chance until the weekend. I use NOD32 AV and I'll see what it tells me. You may want to write Topaz customer service a quick email to let them know. It's probably a false positive, but even so they would want to know about it. I've known about the company for a long time and use one of their products, so the company itself is reputable.
Our firewall at work restricts access to photo sharing sites, so I'll have to wait until I get home to see the picture, and try Ninja on it. I've used it on noisy sky with good results, so I'm very surprised to hear Ninja actually made it worse. I may download Topaz and compare with Ninja before weekend after all.

Unfortunately, yes - this was an iso 200 shot. It's more noticeable with darker blue skies of course.

Holy crap, that's unacceptable to me.
Surely it can't be all 7Ds, has anyone else experienced this?

No, that kind of result is what happens when you mess it up. Lot's of things can produce noise in the skies but it won't be an issue with good shooting technique and workflow.
Additionally, even though that shot shows poor conversion or exposure (it's really impossible to tell because the software used stripped away the EXIF), it looks worse than it is because most people are not accustomed to scrutinizing images at such a high magnification.

I used to only use Noise Ninja, for years. Then I heard about Nik's dfine. I used that for the last year or so. For me it was better, especially in single color areas like the sky.
But a few months ago I heard everyone raving about Topaz. They were right. Its seems to be very soft soft handed in cleaning up noise, NOT exaggerating existing noise, and still leaving sharpness preserved.
There are several settings. I usually just crank up the strength till the preview looks clean. Some day I will have to learn all of the other settings.
I use it as a plug-in to Aperture 3 but I think it also works with elements and PS.

They have - it's probably the selling point they've been pushing hardest of all!
It's not just NR: they've significantly improved the demosaicing, and it's that which will make the biggest difference to your skies.

Nope.
Avoid any "final" sharpening to the sky, as it only creates noise.
(1) You can use a program like NIK Sharpener to omit the sky color.
(2) In Photoshop apply selective sharpening with any "Sharpener" by globally sharpening the entire image, then, in the History Panel, take a Snapshot of the sharpened state.
Next revert back to the unsharpened state in the History panel, and with the History Brush, paint the sharpened state back--only where you want it.

I can also give a thumbs up to Topaz Denoise. It even cleans up the blue skies from my little point and shoot, and it's very easy to use.
Also, keep in mind that if you save as a JPG, all can be for naught because JPG compression often creates junk in blue skies.
Anyhow, give TD a try.

Crickey that's terrible, I haven't seen anything like that in my shots out of a 7D from ISO 100 to 500 and above.
Is your camera OK?
The shot was properly exposed? Sorry to question this but I would be sending my 7D back if it was like that!
I hope you get it sorted as that is really terrible.
As for noise reduction I am quite impressed with ACR 6.2. I also found DPP was not that bad, I found you sometimes had to crank the luminance noise reduction up a click or two on the default setting sometimes. But ACR 6.2 is quite amazing, I have gone from singing the praises of DPP to now singing the praises of ACR 6.2. Just have to see how I feel when I get hold of DPP 3.9 as that has some new features. But ACR is very good now.

Here it is after running Topaz Denoise 5, using the canned "JPG Strong", but with both of the color correction sliders set to zero:
I remember reading, when the 7D first came out, about people getting copies of the camera that seemed to have a problem with creating a "maze like" effect in the conversion. Upon returning the cameras, and getting replacements, I believe many got cameras that were a lot better in that respect, so it seemed as though there was a problem with some copies of the 7D.
How was this shot processed? Was it shot in JPG? RAW? If RAW, what converter was used, and with what settings?
I don't have anything to process 7D RAWs, but someone who does might want to take a crack at the RAW conversion, too.
Anyhow, Topaz does a good job removing noise, and one of the things I've used it for with great success is removing noise in bland areas of solid color from 40D images, too.
