The Adaptive Wide Angle UI
Once you’ve opened your test picture into Photoshop CS6 and you’re ready to start, choose Filter > Adaptive Wide Angle. The interface uses a modal window similar to the one used by Lens Correction (Figure 2 - click to enlarge). At top-left we have tools for creating Constraints as well as panning and zooming, a large preview in the center, lens information and view options across the bottom of the window, the Correction “mode” menu (I typically leave this set to “Auto” unless I’m using a shot taken with a fisheye lens -- there is a “Fisheye” setting), and a Detail view that will help you with Constraint placement.

As I’ve used AWA more often, I find that the Constraint tool (shortcut: C) is all I need (in many cases) to remove distracting geometric distortions in very-wide-angle shots. This is especially true of photographs that have man-made objects, because we can use the lines and edges of those objects as references for our Constraints.
