I film a lot with the Canon C100, I've noticed that when a lot of flashes are going off I get a lot of image issues (which I think is due to how CMOS exposes line by line) (see picture), the effects are more pronounced in slow motion (the c100 only shoots interlaced).
I have a few questions:
whats the technical name of this 'effect'/issue
why is it more pronounced in slow motion (does interlacing effect this?)
and is there anything I can do with regards to shutter/speeds or utilizing 'clear scan' in the c100 to reduce this?
