A method for composition of two digital images which overlap in an overlapping pixel region, including adjusting the pixel color values of at least one of the digital images so as to produce resulting digital images including at least one modified digital image, and combining the resulting digital images in the overlapping pixel region by taking weighted averages of their pixel color values. There is also described a method for feathering two digital images which overlap in an overlapping pixel region, including aligning the digital images so as to approximately register them in the overlapping pixel region, determining three curves, one of which is a leftmost curve, another of which is a middle curve and another of which is a rightmost curve, and at least one of which is not a straight vertical line, the curves extending from the top to the bottom of the overlapping pixel region and lying within the overlapping pixel region, and the middle curve lying between the leftmost and the rightmost curve, and combining the digital images by taking a weighted average of the pixel color values, in such a way that the weights used are a value above 50% of image A and a value below 50% of image B to the left of the leftmost curve, 50% of image A and 50% of image B along the middle curve, and a value below 50% of image A and a value above 50% of image B to the right of the rightmost curve. Systems for carrying out the methods are also described.

1. A method for aligning a first digital image with a second digital image which overlaps with it in an overlapping pixel region, comprising:determining a two-dimensional table of strictly vertical pixel displacements for each pixel location in said first image, wherein the strictly vertical pixel displacement for a pixel location, P, is constrained so as not to be more than one unit smaller than the strictly vertical pixel displacement for a pixel location that is one unit directly below P; and replacing the color value in said first image at each pixel location in said first image with the color value of a pixel displaced from said pixel location by said strictly vertical pixel displacement for said pixel location.
