contrary person

When I was working at the cafeteria in my university, a professor in the department of education came to my house and taught students.He said, "I will never take photos while making a V sign, because V signs make the photograph look poor", which made me think he is cynical.
The other day, I was looking at photographs taken during club activity. There were so many photos with people making a V sign. I couldn't help but think that they are ridiculous. I might be one of those contrary people.
