1. A method of identifying spatial image modifications, comprising: receiving an original image and an adjusted image; identifying a first subset of pixels comprising pixels in the original image that have a same first color value; and determining whether a second subset of pixels in the adjusted image all have a same second color value, wherein the second subset of pixels spatially correspond with the first subset of pixels; wherein a spatial adjustment is identified if the second subset of pixels do not all have the same second color value.
