Re: Behind the lens filters (was [Largeformat] Red Dot Artar 14" f:9)

Wonder if the angle of light has something to do with this.
At relatively wide openings, the rays should travel in a
straighter direction to the film. Maybe, depending on the
focal length, the high angles of the small openings may have
projected the flaws off the edge of the film?
