I didn’t have the facilities to do the exact same as Luigi did in his photo but I took one similar. I took a photo similar but using the same door and person, but making sure that the person was in different positions.
In Bussolati’s photo he shows the rule of odd and even, and the people slowly decrease in focus. I tried to do this but the focus didn’t fade.
In his photos he has take it from above the images, I again didn’t have any facility to recreate the exact image but I took the photo in a similar way by taking a photo of my plate of food from above.
