1. A method for shifting perspective in a composite image derived from a plurality of images including a first image and a second image, the composite image including the first image as a center of projection and a modified version of the second image, the modified version of the second image being corrected for perspective distortion relative to the first image, the method comprising: receiving an instruction to shift perspective to make the second image the center of projection of the composite image; determining a transformation for mapping a set of reference points in the modified version of the second image to a corresponding set of reference points in the second image; and transforming the first image and the modified version of the second image based on the transformation to generate a modified version of the first image and the second image.
