I enjoy seeing cosplay pictures in black and white because you end up spotting details you didn't see before, and it just adds so much more depth to the image. I also think it brings a certain street style and candid element to the shots, which I find very fitting as many of these types of images aren't taken on movie sets or with scenes meant for these types of characters. It is often just extraordinary people in everyday situations.
