Most decent photo enhancement apps for the Mac have a built-in leveler function; a tool which levels or straightens a crooked horizon in a photo, for example. Here’s a tool for Mac photographers that’s the obvious ultimate on perspective. It’s called DxO Perspective and you’ve probably never used an app quite like it.
Instead of simply straightening the horizon, DxO Perspective can also correct perspective issues in a photo. Got a photo with a skewed building? That takes just a few clicks. Need the horizon straightened as well as some of the objects in the photo? DxO Perspective does that, too.
Here’s a typical example. We’ve all had some nice wide angle shots which distort nearby structures. DxO Perspective fixes that with a few clicks.
The tools to straighten crooked, skewed, or distorted objects in a photo are similar to skewing tools with handles. Click the appropriate tool, drop it inline with the object to be straightened, adjust as needed.
DxO Perspective works well on interior photos, landscape photos, even street and architectural photos. The initial perspective recovery is easily obtained in Automatic Crop, but there are additional Manual Tools to fine tune corrections, and Loupe Window to make sure you get the anchor point positions pixel perfect. The app works on JPG and TIFF images (both 8 and 16-bit) but not RAW.
Photos with some skewing or perspective distortion that normally would not make the cut, are easily saved and recovered with DxO Perspective. This is a nicely done, obviously one-trick pony app, but if you’re serious about recovering photos, you’ll find it well worth the nominal price.
