I agree on the ISO, I don't often use ISO as high as 800, except for the concert in L.A. I was sitting in a pretty dark corner >"<
BTW, thank you for the Flickr link, is it possible if you enable downloading for that album so I can save some pics which aren't in here ?
p.s: hey hi-5 for Nikon users !!
Added you to Flickr so you should be good to grab the original file sizes. Enjoy
Let me know if you still have problems downloading the high-res files.
