Just a slight mention on the 24-bit output from the Sculpt range.
It is worthless UNLESS you have an accellerator with math co-processor
and the version of the program designed for this package.
Optimizations used in the standard version for speed result in a huge
loss of accuracy in the final colour information. This improves with the
special versions.
