Ok so I'm anticipating a new K-3 for Christmas, and I've never worked with digital photography before. I just installed Lightroom, and I want to get accustomed to some of the features it offers. I don't intend on doing heavy editing, but the ability to fix exposure mistakes that couldnt be addressed from an impromptu shot is nice. If anyone has a few raw files they'd like to post for me to mess around with in lightroom that would be cool.
