celter Member 99 posts Joined Jan 2006 Location: Oslo, Norway More info | Dec 26, 2006 07:11 | #1 I haven't found a method of correcting severe distorsion resulting from using a wide angle lens at an angle, f.ex. when I am shooting a building and pointing the camera upwards. PTLens can correct the distorsion when I shoot an object with the lens paralell to the ground, but not the severe distorsion I get when I point the camera upwards. Can you help me? 5D Classic, 6D, 7D, Canon 16-35 f/4 L IS USM, Canon 24-105 f/4 L, Zeiss 35 f/2, Sigma 50 f/1.4 Art, Canon 100 f/2.8L Macro, Sigma APO 100-300mm f/4 EX IF HSM, Kenko 1.4X, Canon Speedlite 580EX, Canon Speedlite 90EX, Benro C-227, Benro KS-1, HP Photosmart 8750

In photoshop it's fairly easy to correct by using 'transform'. "I think the idea of art kills creativity" - Douglas Adams

You can fix horizontal and vertical perspective distortion and any combination of both at the same time... AND you can fix barrel or pincushion distortion. Keep in mind though, as with any editing you do in JPEG mode, you risk destroying pixel data so your results (while probably quite acceptable) will never be optimal... with either method. The best way to correctly capture images of subjects while pointing up is with a T/S lens if you want true perspective.  HOSTED PHOTO please log in to view hosted photos in full size.
