Photoshop: Says wrong horizontal FOV in 3D
When you create a 3D layer Photoshop says (calculates) wrong horizontal field of view if the canvas is not a square. The similar problem is when you use the vanishing point filter. When you determine a group of parallel lines in the image and after try to back a 3D layer, the FOV calculations are always wrong, so the perspective of the image and created 3D layer doesn't match. Wherein no matter what type of the canvas the image is: square or rectangle.
