How do I correct fan-out distortion?

Post by netaamit »

When I take selfies at home looking upward at the camera which is high up, straight lines fan-out toward the top of the picture.
I tried using the Warp transformation but got bad distortion of faces in the middle of the picture.
With the Fan tool I can shrink the inner radius. Is there a tool that will allow me to shrink the upper radius?

When using Warp, try clicking the Auto Proportions button after straightening the verticals, or try adjusting the proportions slider manually.

If you want to try using Fan, try flipping the image top to bottom first and then flip the result back.
