I fell in love with Photography a few years ago. Shortly after that I found that Canon’s suite of tools (primarily Digital Photo Professional) was absolutely terrible for editing and managing photos.
I briefly used (and loved) Picasa for it’s organization capabilities (geo-, keyword- and face-tagging en masse). But Picasa–at the time, anyways–was very weak on editing capabilities. A friend recommended Lightroom 3 and I haven’t looked back since (I’m now on v4.4).
Lightroom isn’t perfect, however. It has a few usability issues. One of my pet peeves is that Lightroom for Windows doesn’t support the mouse wheel. I’ll reflexively scroll down… but nothing happens. This drive me crazy.
