They do look a bit smooth after the NR, so try adding an unsharp mask and seeing if you get some detail back. I get noise in clear blue sky like this as well and have to use NR. I am pretty sure the 7D and T2i have the same exact sensor.
Here is a shot that I had to use NIK Dfine and I let it automate the NR and then pulled it back into CS5 and added an unsharp mask of 105%. Take a look and see if it looks any different to you on your monitor. Every monitor I look at with my pictures seems to show slight differences in the amount of noise I see and any artifacting. I saved this one as a Tiff then cropped it to 70% to make it small enough to upload.
That looks great. I don't have NIK Dfine at the moment, and hope I don't have to get it, but I will if I can't get better from the 7D. I also have always used smart sharpen in the past on my other photos (mostly trains planes and cars, along with my pets), but I guess I need to sharpen my CS5 skills!
Here is one of the pics, converted straight from ACR and resized for posting, the second one is a 100% crop. I was pushing the exposure a bit because I have read that that could help reduce the noise. I am aware that I am really cropping it down for posting because I am too far away too, and that could be the cause, but the sky itself just looks way noisier than I am used to with my other bodies espeically at 200 ISO.
Hey, I am new to bird photography, so any advice is welcome, thanks!
