This is what I am seeing also, I get much better results with ACR 6.1 than Topaz Denoise.

High ISO Comparison 7D vs D700.
- Thread starter SpartanWarrior
- Start date
It will have an effect on noise of course, the D700 shutter speed is suppose to have less noise, unless of course your not telling the "TRUTH"

Yep, the low ISO 100-200 blue sky on the 7D is indeed a negative surprise to me! How it comes that this smaller sensor performs so well at high ISO and has this issue with a blue channel?

I have a question is that from a jpeg out of the camera?
I'm wondering if its from jpeg artifact. Would a slight chrominance noise reduction reduce that or is it only noticeable on 100% crop?
I don't really trust the camera jpeg conversion and only shoot raw and do my own convert to jpeg.
For my own I disable all in camera processing like high iso noise and especially highlight tone priority.

If the lighting in the shots for both cameras is infact the same, then this should be translated to any real-life application. Suck it up people. Why can't you just take the shots for what they are. Stop with all of this Tom Foolery!

Even disregarding the D700 for a moment, there's something fishy with 7D's ISO rating. See how when going from ISO 1600 to 3200 the shutter speed didn't double? Either Canon's been sneaky or you did something wrong. Anyway, as others have pointed out, by ISO 12800 D700 gains more than a stop in shutter speed so this isn't exactly a valid test.
If you want a meaningful test, go out and actually take photos in low light where people actually use high ISOs for. Also, take something with colours and lots of it. Tests like these don't usually show the full abilities of good high ISO sensors because they lack colours. I'm willing to bet you'll see a visible difference that no amount of resizing will change.
Now, the D700 sensor is 2 years old and 7D is Canon's latest effort. We all know how fast sensors technology advances so it shouldn't a surprise that the gap is closing between the latest APS-C and older FF sensors. Having said that, 7D has done remarkably well with noise control. I think it goes to show Canon has the superior sensor technology to beat Nikon/Sony....They simply choose not to compete head-on, which is a real shame since they keep crippling their own cameras.

Interesting. Maybe I'll try some tests again, but when I first got my 7D I thought DPP did better at NR than ACR (which was a beta version), and I feel like Noise Ninja can beat both.
I'll have to try some controlled comparisons with the latest ACR.

No, as I wrote, its a raw file converted by Lightroom 3.0, no processing, to a 1:1 max size jpeg of a 100% (best possible) quality. I never shoot jpegs.
This low ISO blue channel issue with eos-7d was reported by many people before.
Thomas
I'll agree with the LR3 comment on NR, at least against Noise Ninja. I have the paid, full version of Noise Ninja and I still prefer LR3 
(though I should try NN again - haven't touched it in a while, and maybe they've improved it).

MUCH appreciate it actually as I am about to spend $5000 on "some" new camera and have been collecting real world examples of raw files.

However, these are:
-ISO 100 OUTDOOR daylight shots both from the 7D only :-(
-DNG format, not original camera RAW out of the camera
-Not the same shot as your example above.
Can you simply post the Nikon and Canon RAW files out of the camera for the above example you used? It would answer a lot of questions as to the findings. I am curious to see if it is indeed that little difference or if the 7D is indeed better than the Nikon. If the 7D is as good, I will consider [it] instead as it has a "few more pixels"
Thanks...

DNG is fine if it is all you have Never really worked with DNG... is it supposed to be RAW data as well or has it been massaged by Adobe during conversion?
Thanks much

Have you tried the same RAW file conversion with DPP? I've not used LR for 7D RAW's but I've never seen anything that bad in a blue sky using DPP with serveral 7D's. That's truly horrible and reminds me of the bad results I got with ACR converting XTi RAW files. I was so disappointed I sold the camera but later opened the RAW's in DPP and the blue sky grain was gone, smooth as silk.
Here's a RAW ISO 200 7D file converted with DPP using "standard" picture styles (default shapness of 3) with about another 150 of sharpness added in the RAW window.
