Yes, experienced all that and at that time came to the very disappointing
realisation that digital B&W is only possible when not using glass filters.
Fortunately, I can across FilterSim and DXO FilmPack and can pretty much do
what I had desired from the start, just not in the manner that I became used to
with film.
However, I can correct for colour temperature with 81 and 82 series
Wratten filters instead of changing the internal colour temperature setting,
which suits me fine. The plus side is that I only need to take a small set of
ND, 81, and 82 glass filters with me.
This reminds me that I need to return to becoming familiar with GIMP and
see if it will accommodate the PS7 Wratten filter actions.
