The presence of the things close by...and how we attach relevance to them....
How dependent is this of a person running through or not?
Is the material agency of the direct foreground only activated through the presence of the subject running through?
I have read some of Paula Kramer's PhD thesis " Dancing Materiality', ...but she dances in the vicinity to the material scene that she has created...I am moving away from it, leaving it to the camera and it's not so clear role in it all, to 'define' things.
