Thomas is always a pleasure to work with and bounce ideas off.
Unfortunately, the AtariAge thread has attracted one or two people who don't
know how to constructively encourage experimentation and progress - and
instead belittle and/or disparage the participation of others.

Enough said - the fine Stella gang to the rescue!

Personally, I am absolutely TOTALLY against a technique which requires hand
optimisation/processing.  Tools, utilities... and perhaps a handtweak at the
end.  But certainly as little hand-manipulation as necessary.  None of my
images, so far, have been handprocessed on an individual basis.  That is, my
procedure is the same for all.

Cheers
