In this week’s free Deke’s Techniques episode, Deke shows you how to repair the distortion on a stitched panorama using Photoshop’s Wide Adaptive Angle filter. To ensure that the exercise is a true challenge, he has used nineteen gorgeous shots of the Guggenhiem museum in Bilbao, a building which is itself a puzzle of unexpected alignment. 

Along the way, you’ll discover which things are best tuned-up before photo-stitching (exposure, lens correction, chromatic aberration, and general raw conversion), which are best ignored (the layer masks in Photoshop when you have 19 different contributing images), and what to fix after the stitching is done (the aforementioned distortion, cropping, and recreation of lost areas). 

For members of lynda.com, Deke also has a follow-up movie this week, in which he demonstrates how to fix some stitching errors in areas that require precise matching up. If you’re already a signed-in member, you can catch that video by clicking on the image below:
