A fold beside
a filter.
Read the visible relationship before naming its purpose. These paired references invite a question; they cannot settle material history.
One sheet, two contexts.
Compare the assembled relationship with the sheet on its own. A fold changes a flat sheet into adjacent planes.
Observation
A dark slotted block, amber-colored translucent strip, folded white sheet and bent metallic line overlap on one plane.
Interpretation to test
The strip changes the apparent color beneath it. Folding creates the paper’s own light and shadow. The wire meets one edge. These are visible relationships, not proof of intended function.
