I'm a fan of the one touch photo editing in Picasa. Otherwise, I like using iPhoto (despite the lack of effectiveness using "Enhance"). Clicking enhance often makes the picture look worse instead of better. With that said, is there a better application for Mac OS X that has a good one-touch photo editing feature? I'm not very good at editing the photo myself and would love to be able to make the pictures look better without much effort. I've read about Lightroom and Aperture (not interested in Photoshop). Do either of those offer this feature or something similar? Thanks!
