Reply #11: They don't link to details on that page in Flickr

But it is there - here is all the detail that could possibly be attached to a picture I think :) :

Loaded it into Lightroom 2 and exported is as 16-bit TIFF.
I applied some sharpening and noise reduction in Photoshop, using the plug-in called Noise Ninja, to get rid of the ISO noise - which wasn't too bad on this picture, thankfully.
Converted to 8-bit and exported to JPG and uploaded to Flickr.
For this one I uploaded the original and Flick then resizes it for the other sizes.
For everything else in the two sets, I batch processed them in Photoshop to JPGs with a max width or height of 1024 and uploaded them.

The light they put on the stage is what provides the magic - and your working conditions. Thankfully the lead singer is out of the smoke almost all of the time. :)
I started out with aperture priority, because thats what I seem to read everywhere that people do for concert shots. But since I had maxed the ISO out at 1600 and I could see that f/2.8 would force it to too slow shutter speeds, I changed to shutter priority and could see from the results that it was good enough. Played around a little with the shutter speeds and zoomed in on the results on the display to see what they delivered in terms of sharpness, and decided to stay with 1/160 or 1/200.
It was an outdoor concert btw - but it was almost entirely dark at that time.
