Question: Some pictures or illustrations are black like a shadow and they don’t have the characteristics of a clear picture. Is this allowed?
Answer: “There is not in it a clear picture. It is only the shape of a head and other than it. It is like something that is obliterated. Like something that is wiped/obliterated”
