I'm a new Lightroom user, and so far I really love it! I've been adding photos to my Lightroom envronment that I took years ago. It's fun practcing what I've learned by watching several of the Adobe training videos. Prior to moving to Lightroom I was using iPhoto. Everything in iPhoto was organized by events. I'm just wondering how most of you organize in Lightroom. Do you use collections or catalogs? So far I've started making use of smart collections that are based on meta-data keywords. Just wondering if this is the approach others take. I appreciate any input!
