No More Keystone Quilt

When you photograph a quilt or other flat, rectangular artwork, watch out for keystoning. Keystoning happens when the edges of the quilt are not parallel with the edges of the camera frame and the quilt looks crooked, with one edge shorter than the other. To prevent the keystone quilt look, photograph the quilt straight on, with the camera centered on the quilt side to side and top to bottom, and make sure that the camera lens is sitting parallel to the floor, not tilted up or down slightly. If the picture looks slightly crooked despite all your precautions, some photo editing programs can apply a filter to correct keystoning and other camera distortions.
