Adobe has also worked on its algorithms for automatic fixes, and they do seem better. Auto Tone and Auto Contrast actually do a nice job, provided you start with an image that's not too skewed toward one end of the histogram or the other. They're still not great on grossly over- or underexposed images, as they seem to be a bit too conservative. The painting engine now offers erodible brushes -- brushes whose effect lessens as you use it -- plus enhanced airbrush tips. You also get a much better real-time preview of the bristles, and a great heads-up display can show you how the brush tilt and rotation is registering within the application when using a pen and tablet.
