I have just got Lightroom 3 and was playing around with it and found very fast how much better it is then 2.7.
Tested on a photo I had taken away with the old lightroom and this is the result.
Will now start to go true my shots from my expedition to Brazil, think this will make then better especialy on the noise.
If you want tips on lightroom check out Patriks site:
