Did you use LR to initially process this image? That 100% crop looks like ISO 3200 to me.
Be careful with LR; if you set the detail to more than about 15 at ISO 400 it creates a a graininess in areas of low texture, which makes the image look noisier than it really is. No ther RAW converter I've used does this and it took me a long time to realise this was why my 7D shots looked so grainy, even at modest ISO.
For my 7D my LR settings at say ISO 400 for sharpening and NR would...Show more →
I agree completely. To me, the 100% crop looks more like what I'd expect at ISO 2500-3200 with the 7D. I can't figure out what has gone wrong with this one, but it certainly is not what I'd expect at ISO 400 or 800 or even somewhat higher. How much of an exposure adjustment was done before processing? My first guess is that it looks to me like the result of some extreme adjustments done prior to conversion.
For comparison purposes, below is an ISO 3200 shot from a couple of days ago and a 100% crop. Note that the shot was taken on an extremely cloudy day, and I normally wouldn't even bother to shoot on a day like that because I don't like the pictures from cloudy days for reasons other than noise. Also note that I don't have nearly the skills as some of the others do at processing, post processing, and dealing with noise. For this shot, I basically just used default settings for dealing with noise in ACR. The converted TIFF just had a slight shadow/highlight adjustment and some sharpening. While the noise is visible in the background of the 100%, I think it disappears nicely in the full image, and, at ISO 3200, I'll take it, which is why the image that Conrad posted at ISO 400 puzzles me. And, again, I know that some of the others posting in this thread could do a lot better with the processing than I did.
