If you use LR3, would you mind sharing what general capture sharpening settings you use? Obviously not everyone uses the same settings for everything, so maybe you can break it up into typical settings for portraits vs. landscapes, etc...
The reason I ask is that I've found that the sharpening in LR3 is a bit different than what I'm used to, and extra-special care is required for the very pixel-dense 7D/T2i sensor. I tried a quick search for this on the forum, but didn't find a thread on this topic exactly.
To start things off, here's what I use as my general sharpening setting (which I then change to suit the picture in question):
Amount: 80
Radius: 0.9
Detail: 0
Masking: 60
I find that increasing the 'detail' slider too much introduces a weird "paintery" effect when the 'amount' slider is high, especially in areas where there is noise - this is why I keep it small (maybe up to 5 at the most). If I need more sharpening, I'll instead increase the 'amount' up to 120 or 130, increase the radius to 1.3 or so, and decrease the masking to maybe 30. FYI, I can get similar results bringing the 'amount' slider much lower, but instead increasing the 'detail' slider - as long as 'amount' is low enough, I won't see the "paintery" effect.
Finally, I don't do any output sharpening when I export my JPEGs, since I try to sharpen enough during capture sharpening for my targeted application.
