all right... so i took a picture of the room and my hand with the filter. THEN i took another picture of me in the spot where the filter was... took the two pics and put one on top of another and wamo! the picture is there!! oh and the camera was on a tripod so it was really easy to line up all the lines and stuff. so there you have it!
Nice and creative idea..if the frame of the circle were more sharp it would be a bit better...seems as if the piece is a way to see the past kind of...black and white...as if that's like a spirit or something still present but invisible to the human eye...you can take it in other ways too..
I would have approached it differently but your style works for it. Nice job.
