"Before / On / After: Permutations" by William Wegman is a series of seven gelatin silver prints that explores temporal sequencing and conceptual permutations through systematic photography. The work exemplifies Wegman's interest in language, logic, and visual wordplay, using the tripartite structure of before, on, and after to examine how meaning shifts across different orderings and contexts. The dual mounting technique (flush mounting followed by secondary mounting) emphasizes the materiality of the photograph while reinforcing the work's conceptual framework about process and presentation.
