I used to be unappreciative of the 7D's tiny pixels, as I saw these as noisier at the pixel level than earlier EOS DSLRs. But when I learned to optimize the processing, NR and sharpening of 7D files, I began to appreciate the extreme detail gathering potential of the tiny pixels, even at ISOs higher than 400. Now, my view took a 180 degree turn around - I'm actually looking forward to even tinier pixels of future EOS DSLRs. In a couple or so generations, I hope pixels will be small enough such that existing birding lenses need not use teleconverters to harvest the full resolution of the main optics. The benefits of such system are no loss of AF speed and light which are inherent in using TCs. To illustrate, here's a macro shot from this morning. 7D + 100 2.8 USM macro, f/8, 1/250 sec, ISO 800, hand held, manual exposure in available light, spot AI servo, 100% crop, screenshot of DPP conversion, zero NR applied (standard PS) . Noisy as hell? Yes!!! 100% crop - converted in ACR 6.1 (camera neutral PS) , NR and sharpening applied, before levels/contrast adjustment: And a processed, resized version with optimized NR and sharpening. The detail and much information were captured by the 7D sensor. One just needs to "separate the grain from the chaff".

Amazing denoising work, Ka Mastah. It would be interesting to see a 100% crop comparison between the original and processed images.

Excellent job on de-noising the phot Ka Mastah! Now let's see if Canon can come up with a 7D MK2! :-)

Nice de-noising job Mastah? Do you use a separate PS plug-in for NR and/or sharpening? Or you do everything in ACR?

Thanks for the comments, folks! Nice de-noising job Mastah? Do you use a separate PS plug-in for NR and/or sharpening? Or you do everything in ACR? Adri, I mostly use the built-in NR tool of PS. When the noise is really high, I sometimes convert the RAW twice in ACR - first is optimized for NR and the other for detail. Then I just combine the two in PS.

Thanks Mastah. I'll try that in my very noisy pied fantail pics!

Boy that really work's. Thanks for the tip. This site rocks. I have had my 7d for about 2 months now and had given up on it for high ISO shots. Just tried it on a speckled barwing. Marvelous
