Hi, I'm from Minneapolis, MN but currently a student living in Malibu, CA. I bought a Canon XTi about a year ago. I'm just starting to try to move beyond the basic modes on the camera. Hoping to become a better photographer and gather some tips and tricks from the forum. I have a MacBook, is there any consensus on the best editing program for a Mac? Lightroom, Aperture? Right now I have the 18-55mm kit lens, but I'm going to be purchasing an 18-200mm lens soon!
