Back in 2565 BC cameras weren’t that advanced like they are today. Due to the long exposure time these people had to stand still for several hours in order to avoid too much blurriness of the photo. You can see that the people in the background (middle left in the photo) were moving slightly as the photo is a bit blurrier compared to the foreground.
I didn’t know. I thought it was some old painting which depicted something in a totally different and unknown context, like so many others in this communtiy. It is never too late to learn.
