For over a year, I had been using LR2 because it wouldn't run on OS X (Tiger), and I wasn't about to enrich Apple with $129 for an OS upgrade. When Fry's suddenly offered it for $29 I installed Snow Leopard, fought with the things that stopped working, like printers, until I understood how Apple had reorganized stuff. Then, yesterday, I installed the LR upgrade. So, it would be interesting to know what the major changes are. Most things look pretty much the same. I understand they claim that they have improved the noise reduction, but it is so pathetic compared to what NoiseNinja will do in its most simple-minded automatic mode that I would not even bother with the LR noise reduction facility. Interesting point about NoiseNinja. They provide a chart which can be photographed with various cameras at various ISO values, the idea being that you create noise profiles from those photographs and then use them to reduce noise in subsequent photos. Well, I tried it, and to my surprise found that the dumb simple way of using it produced better results. The simplest way is to go full automatic. The software finds a number of uniform areas in the picture, samples them, and then produces a profile for THAT picture which is then used to remove noise. It does show you what spots it is sampling. It can be fooled if some area with uniform microscopic detail looks like noise. I found one photo where the automatic procedure did not work. In that case, one has the option of manually selecting small areas in the picture that should look uniform, drawing little sampling rectangles just as if one were cropping out tiny areas. I.e., you're telling the software where sample the noise. One drawback is that it produces .tiff files that are over 100 MB in size. They can be cut back with what I think is loss-less compression, but that becomes an extra step. Can anyone summarize for me what other goodies besides backing up at a SANE time differentiate LR3 from LR2?
