Whats fun about Auto is that once you run it, you can cycle through the three filters to see the different types of corrections, and then choose the one you want to use. On this shot of the Willie McCovey statue at San Francisco's AT&T Park, for example, the Temperature & Tint version was the best starting point, with the Natural Gray option a bit cool for my taste.

Keep in mind that these corrections are brushable too, so you can further adjust the color in specific areas.

One tool, Highlights & Shadows, was rewritten and streamlined. It now preforms faster, and the output seems better too, or at least potentially less damaging to your images. The primary improvement is the virtual elimination of halo artifacts that could result from heavy handed image editing.

You may also notice that the brick has been trimmed to 3 sliders: Highlights, Shadows, and Mid Contrast. The sliders that were eliminated (Radius, Color Correction, High Tonal Width, and Low Tonal Width) were combined into the rewritten existing sliders. Apples view is that you dont need the eliminated controls because they are more intelligently applied into the current sliders.

Our testing supports Apples view that the new controls provide smoother tonal results. But I do miss having the set of Advanced sliders from the previous version.
