I've got a project shot with a bunch of DSLRs. Since symphony tends to rely on the "tape" column to color correct en masse, this leaves me in an awkward situation: adding 'tape' data to these files will delete their 'source file' column data. I suppose this is logical, since Symphony is trying to say "hey, this either came from a tape or a file, not both, dummy!"
But then... what data column can I use to assign a common value to all these files, and have symphony use it for color correction ?
