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).
