wow Mark… to make this happen is so incredibly involved compared to the 1980s when it all happened so easily. We lived and died by comet-trailing and posterization – especially when it added absolutely nothing to the production.
Additional notes – you forgot to mention the use of “controlled” feedback through the DVE. Always gave that special look through the ADO 1000.
Chyrons often were done in yellow “because it read better” over the overly lit footage – still no edge and the worst drop shadow possible.
This all wasn’t JUST public access – most broadcast was the same.
