Comets
J.-L. Dighaye
The left-hand picture shows the comet as it would appear as the result of a
conventional photographic enlargement. The right-hand picture shows the
effect of a non-linear processing similar to a photographic solarisation,
bringing more contrast between the comet's inner and outer coma
(black and white, respectively).
