What would it be? I just got my MBP, and am going to buy one piece of photography software. I am going to be taking a lot of 'art' photos (landscape, streetscene, etc.) and snapshots of family and friends. Assume that the price difference doesn't matter (I get an educators discount on the software) and I am looking at Aperture/Lightroom or Photoshop. I will do a trial of both Aperture and Lightroom to see which I like best, but am wondering if it would be better to purchase Photoshop? I don't really know the full extent of what can be done in Photoshop, as I have never used it, but it seems to be a standard. Is it worth it for a hobbyist to own it? I ask this knowing full well that I will likely buy Photoshop eventually, but am wondering if I should buy it first and get Aperture/Lightroom later?
