Teamspeed, what NR setting did you use for your ISO4000 OOC JPG?

90% of the time I use standard, in rare cases I will go to low (depends on my goals for processing) or high if I just want JPGs and not completely care about total IQ. I have to assume standard on that shot.

I've owned two 7d's.
The first one (I was an early adopter) was just great.
In the first reviews the 7d got good results, but then I saw all kinds of complaints on the web about it being noisy. I couldn't understand why, as the results I was getting from mine were quite good and matched one or two of the initial reports (reviews) from the camera, right after it was announced.
So at the time I guessed people were really demanding and were just expecting full-frame like results.

I sold it and then, some time later, bought a second one.
It was noisier.
Dare I say, much noisier...

Then I understood why people were complaining.

IME, this level of noise at the pixel level won't be noticeable in prints. For web display at reduced size, it's quite simple to filter out the noise, as you have shown in the first photo.

Have you tried ACR/LR in conversion? "Cross-hatched" and "white-dot" types of noise are minimized with ACR/LR when compared to DPP.

And here's an unprocessed 100% crop of the same image. Its a bit soft because of the lack of sharpening and because it was shot with a 2x TC:

Your excellent samples and insights didn't disappoint, TS..... that ISO 12.8K shot is insane!

I see that your workflow is DPP-based. I personally favor ACR conversions because my experience shows ACR can extract more detail than DPP at similar noise levels. Alternatively, ACR is less noisy at the same level of details.

This just shows that regardless of one's preferred workflow, 7D files can be useable at high ISOs if captured and "cooked" right.

Sure Romy, I will bite!

Here are my thoughts on the answer to the question posed, and this is based on 3 years of threads of "the 7D is noisy", and my own workflow developed during this time.

The reason for variances isn't so much camera variance (I have had 3 through the years with very slight differences, if any) but rather because of a combination of the following 3 things.

- Underexposure of the image by 2/3 stop or more
- The software tools utilized to process the raw and jpg files
- The skills of or the techniques utilized by the person

I too had first hand experience with copy-to-copy variations. My first 7D was unusually noisy so I exchanged it. My current one is good, as nice as the pre-prod unit I tested way back and the 3 other 7D's I've used since.

I usually shoot birds with my 7D at up to ISO 3200 (or even higher if necessary), and feather detail is still ok to my taste (YMMV) to make at least 12"x18" prints.

I often come across forum posts mentioning the unacceptable noise of the camera even at mid-ISOs. This leaves me wondering if such is a result of:

1. The noise characteristics of 7D files has a large variance from copy to copy;

2. Some 7D users haven't optimized their capture and post-capture workflows to make the most of the 7D hardware and the info it gathers;

3. Noise tolerance varies widely from

I find the results can vary enormously, but getting good focus (noise seems worse even in slightly oof shots), and exposing to the right can give me either clean files or files that clean up with minor NR.

At times I have thought wow this is crap, but at others I have thought what's all the fuss about. I have modified my workflow too which has helped.

ISO 6400 shot, which I wouldn't have considered at one stage.

Amazing that ISO 6400 cleans up so well, Whayne!

Yes, ETTR is a standard capture technique for me too, as it helps tremendously in minimizing noise.

I shoot 100% M mode, so sometimes I couldn't adjust the exposure fast enough on some skittish birds, resulting into underexposed shots. Still, the 7D files process well enough even when pushed.

BTW, this was among my first birdshots using FW 2.0. Absolutely no issues so far - all my MFA values were intact and as accurate as the previous FW.

Interesting to see the LR workflow. I tested the 7d's 12800 this afternoon and found that being aggressive on the OOF noise reduction and then adding a little NR for the overall followed by sharpening really worked well.

Thanks for sharing your very effective workflow, EJ!

The nominal ISO is only a rough proxy of the exposure, and it's the actual exposure (for which the ISO doesn't apply) which determines how much noise is in an image. For example, you can have an ISO 3200 photo with a higher exposure and less noise than an ISO 800 photo.

At mid-ISOs, say ISO 800, I find that noise is even easier to control.

Wow Luminance 40, I used 30 and set mask to 75 and detail to 5 in my ISO 6400 shot in LR to avoid losing too much detail in the bird and exaggeration noise, and then used noiseware 5 to do the final cleanup in PS. New noiseware engine did a great job of preserving details.
