Hello Everyone,
Just testing Arriflex BL16 camera. Today I received test footage from Cinelab. There are vertical lines which appeared in the middle of 100' daylight spool.
I admit I loaded magazine in pretty much dark but not totally dark room. On the same take there was one line and then there are two lines. The lines stayed there for the remainder of the footage. Sometimes as one line sometimes as two.
I would appreciate if someone could enlighten me what would be the cause of it.
