1. A method of identifying a photographer, comprising:

  • (a) determining a steadiness signal related to hand tremor movement of a camera held by a first photographer while capturing an image or video, wherein the steadiness signal identifies a motion of the camera in at least two dimensions as a function of time, further including providing at least two flames from a video, and storing the flames in memory and comparing corresponding pixel values of the frames for determining the steadiness signal;

    (b) storing a set of steadiness signals where each steadiness signal has an associated known photographer;

    (c) using a processor to compare the steadiness signal to the set of steadiness signals to produce a set of similarity scores between the first photographer and each of the known photographers; and

    (d) using the set of similarity scores to identify the photographer that has captured the image or video.
