That's moire patterning caused by the interaction of the fabric pattern and the camera sensor.. To mitigate this when shooting it helps if the background is slightly out of focus. Use a wide aperture and stop down using an ND filter for a shallower depth of field.</P> Mon, 10 Mar 2025 09:32:04 GMT IamintheUK 2025-03-10T09:32:04Z https://community.usa.canon.com/t5/Professional-Video/Weird-striped-pattern-on-background-with-C300-mark-iii/m-p/538219#M4984 <P>Hello!</P><P>Does anyone know the cause of this striped pattern on the background?
