I'm kind of really excited and had to share. I just bought Lightroom 5! But before I start messing around with it I want to watch some tutorials and read some sites about it. Any suggestions for a complete lightroom beginner? Previously I used Aperture, but since I built a new computer (non mac) I decided to go with Lightroom. 4.2gig OC 6 core processor and 16gig of ram should handle well. Aperture slowed my MBP...
