Is anybody here?

This photograph is the result of a double exposure on film that I made in July 2019.

While strolling through Venice, my attention was caught by an elderly lady dressed entirely in white who was a few meters ahead of me. Stopping at the doorway of a palace, she knocked on a door and was opened, after which, instead of entering, she lingered in front of the door. A particularly pleasant guitar sound came from inside the building. I, therefore, photographed the woman intent on listening to the music and then walked on again until I met a street performer intent on playing mandolin. I, therefore, stopped the rewinding of the film and shot again, achieving this result
