I need some tips on getting rid of keystoning in Photoshop (too late in camera as I am back now).

Below is a stitched image of Notredame.




Well this image is more barrelling distortion than keystoning.

I am afraid I dont have a quick or even ideal fix!


I have in the past, used CS Filter>Lens Correction or Distort> Pinch/Spherize, followed by Image>Transform>Warp on images like this. But there is some loss of definition using them, so you need to work on high res and sharpen afterwards.


Personally I would do any corrections on each frame before stitching... to help the software's interpretation.
