I think that's really bending the rules.
The purpose of the contest is to see what a renderer can do. In order to
achieve this purpose, only the image output by the renderer is allowed.
Adjusting brightness/contrast is in the limits of this, although still
allowed.
However, improving the antialiasing of an image by post-processing it
with a paint program clearly breaks this purpose and the rules. The resulting
image is not what the renderer generated, but it has been improved with
a paint program.
There's a simple way of seeing the difference between adjusting
brightness/contrast and smoothing an image by scaling it smaller (ie.
improving its antialiasing): If the image has some pixel-sized artifacts
(which usually appear due to bad antialiasing), brightness/contrast
adjustments will not do anything about it, but they will still be there.
However, scaling the image smaller can get rid of these artifacts. Thus
what it is doing here is to remove artifacts produced by the renderer with
a paint program. The resulting image is not the one produced by the
renderer, but an improved one.
If that's not illegal post-processing, then what is?
How is this different from, for example, applying a blur filter with the
paint program to remove pixelation? Why blurring should be any more illegal?
