Its a production camera and not really made for run and gun shooting. If I was to go that route I would simply download a days work into resolve adjust WB, exposure and tint and then output to prores. Then delete the raw. Minor tweeks hold up well with prores for the final grading.
For me the most difficult thing would be to select what glass to use with an EF mount no less. Kind of wish it was a e-mount with a 12mm Zeiss for WA.
Anyone know what the red guys use for the epics?
I know some guys who have been shooting underwater with the Red Epic and the Tokina 11-16mm. It seems to be pretty sharp with a big dome- and I've been happy with it on the 7D. It's better at f8 and beyond.
