Title:
    Horned Owl
Author:

Description:
    The original image was taken in July '90 with a Canon A-1
    and FD35-70 on Ektachrome, 100 ASA, on July 1990 in Alaska.
    The photographer (me :-) is reflected in the eyes (@left),
    and is being completely ignored by this magnificent bird.
    Digitization was done via PhotoCD. From 4Base resolution,
    the alpha channel was created by edge detection and floodfill.
    Low-pass filtering (norm. cut-off 0.2) was applied to create
    a soft alpha mask. The final result was shrunk by half.
