7D and High ISO noise reductiuon settings

From what I have been able to pick up on here in the forums, leaving the 7D set to either low or standard high ISO reduction will not slow the camera down. What I am really trying to figure out (since I am new to the 7D) is if leaving the camera set on low/standard high ISO noise reduction has any detrimental affects on the overall detail & photo quality of the 7D's lower (100-800) ISO photos. I have tried doing a set of test photos and I can see the difference the noise reduction makes in higher ISO settings. If it does not degrade the photos in lower ISO settings I will just leave it on low or standard. What are the opinions of the those who have experience with this?

I had the same question but the conclusion was to DISABLE this feature and act manually un postprocessing.

I had a tremendous experience doing 30" nigt shots with this feature enable, also long time exposure noise reduction (or something like this) and the foto were AWFUL.

For me 7D is the BEST camera I have ever had but some features must be turned off, RAW shots....Lightroom.

Otherwise, like what I have done, is to register C1-C2 or C3 with noise reduction settings on HIGH and use it when necessary.

Which kind of test have you done? Standard and high decrease sharpness or which other problem arise?

thanks!

Set high iso noise reduction setting to STANDARD or LOW,
Set long exposure noise reduction to at least AUTO,
The key here is CORRECT EXPOSURE,
Dont under expose now and push later,
and dont forget the tripod.

What do you think about this photo?

Thanks for the replies. In the test photos I have taken I can see the noise reduction working in the high ISO photos (although the effect is minimal at 1250-1600 ISO). My concern is, from what I have read, the noise reduction is still working even on low ISO settings. But with my testing I am not seeing it in the 100-800 ISO range nor do I see any loss of detail. I am mainly just looking to see if that is the conclusion of others as well.

Just set the camera up like i said,DONT under expose and push later on computer,
use a good fast memory card, GO out and shoot like nobodies watching you .
forget the B/S for awhile and have fun,and learn from your MISTAKES.

High ISO noise reduction works to some degree at all ISO settings according to Canon. I prefer to leave it turned off and deal with any noise issues in PP.

I always leave it on Standard, and never worry about it. If there is any negative effect to low-ISO jpg's (say ISO800 and below), I don't see it (but I don't pixel peep either).

If it's an important shoot, I'll shoot RAW and deal with NR in ACR.

What I have found is at really high ISO's (say, 3200 and above), I get better NR results shooting jpg, in-camera set to Standard, picture style on Neutral, then a pass through Neat Image with default settings.

I've tried to shoot RAW and use the excellent ACR NR, but I just haven't been happy with the results at 4000 (I shoot two HS hockey teams, so I probably have 10,000-15,000 images at ISO4000 before the seasons are over).

I presume you're shooting JPEG? If you're shooting RAW, the in-camera NR has no effect, so it doesn't matter what you set it to. For JPEG, the NR works to some degree at all ISO settings, but is less visible at low ISO. I keep mine set to low. On the occasions when I shoot JPEG (sports), I find that to be the best compromise between detail and noise. I shoot basketball occasionally from the stands, using ISO 3200 with NR at low. When I resize the shot to 1200 pixels for web viewing, I don't need any additional NR. I would recommend shooting RAW whenever you don't need huge buffers or huge numbers of shots on your CF card. Lightroom has really excellent NR. Since switching to Lightroom, I haven't needed to use Noise Ninja, Nik, or Topaz NR programs (all of which I have).
