what happened with this system when you ran the film backwards- did
the presets understand the direction of the film? I would guess not,
and that you had to start from the beginning each time, or else count
back manually and reload the preset to suit.

Dubner would then have been the very next scene-by-scene correction
system? I do remember getting new software releases on 8" floppies
from Dave Tosh (Chief Engineer at Action Video) and being amazed at
the foresight of the engineer at Dubner who wrote the code (have
forgotten his name, perhaps Dave can recall). Autoread, Autopreview,
Autowrite, .. they still seem to be advanced features. And nothing
later ever compared with the Holtz/Tosh white compression system,
available in 3 channels; it allowed an amazing degree of curve control
in the highlights. We were however limited by the signal out of a Rank
Mark III Digi3, and then Digi4. The Digi4 was orders of magnitude
cleaner in color than the Digi3..
