How to Remove Perspective from a Texture in Photoshop
Capturing texture map images often leads to images with skewed surfaces or obvious vanishing points.
In this topic we'll show how to quickly remove any perspective distortion from an image.
Open an image file in Photoshop (File > Open).
Select the Perspective Crop tool (c key) then drag a rectangle in the document.
Drag the corners of the crop selection to match the image's perspective.
Press Enter to crop the image and remove its distortion.
