At the Hagia Sophia museum in Istanbul Turkey I'm going to photograph. I took the photo from the internet due to the pandemic process. It is visible information how many people came to this museum in one day. Because you can get a certain fee at the entrance and enter with a ticket. But the age groups of the people coming to the museum, whether they are tourists, their gender, their behaviors are invisible information. What people are interested in the museum depends on everyone. What this change depends on (gender, age groups, etc.) is an invisible information.
