I was browsing through my local Apple store carrying around a copy (the LAST copy) of Aperture and "Apple Pro Training Series: Aperture (Apple Pro Training Series)" like I was ready to make the purchase. Now I'm no professional photographer. In fact I take pretty average pictures which is why I want some software to make them look better. If I was a good photographer I wouldn't need touch-ups. A eventually stumbled upon LightZone. Now this seems much more useful to some one like me than Aperture. While I have a couple thousand photos in iPhoto, I don't usually need to compare rolls of photos from a photo-shoot. There is also an apparent user base out there too. The negative info I could find was a review on VersionTracker that claimed the software was too slow because it was written in Java. I don't know about that, but it did win Best of Show at Macworld Expo 2006. I still have not decided, but LightZone is looking pretty good right now. If I finally decide on a new Camera that supports RAW format, it might push me over the edge to plunk even more money down on some better editing software.
