This is just a gas! I am working my way through Scott Kelby's book, and having so much fun with my old photos.
I haven't been scrapping much because I have been scanning a lot of old photos and playing with Lightroom. I know I still have a lot to learn about PSE, too, and the Kelby book on that is next on my list, but for now, all I can say is: I am amazed at what Lightroom can do. Some old scanned photos that I thought were beyond hope are coming to life.
I am probably still quite heavy-handed and clumsy in my use of LR adjustments, but I am having a great time with it and still learning. I wasn't sure if LR would be as useful on scanned photos as on digital photos, but it seems to be.
AND, I have finally gotten all my photos organized on my computer!
I just posted a page about how much I love Lightroom
here.
