Thinking about the marks created around the visible mark when being placed there. So here…thinking about all the finger marks made onto the surface whilst tape was being placed there. Not visible, but skin will have touched the surface, so something will have been left behind.
Accidental ink marks here, surrounded by small pencil lines to show the area surrounding that may also have been impacted upon, but the marks less visible.
Here, showing possible marks around the dropped cigarettes…ash, heat marks, places the cigarettes could have first landed and moved from. Here there are two sets of marks. Physical objects left by a person and then the marks that the cigarettes themselves will have left.
