I'm shooting a film in a month and a bit all on S16 with 250D film stock. We are shooting a scene in a department store that has all fluorescent lighting (photo below). We don't have the budget to replace all the tubes in the store and I was thinking of shooting it mostly with the natural fluorescent light for the wides but adding more fill and shape in the closeups. A possible question that would raise when I'm doing this is the flicker. Will there be flicker? Would checking flicker from a DSLR in video mode be a suitable way of testing for flicker or would I need to play with the shutter in this instance and run some actual tests from the lab.
Looking forward to your responses.
