refer to "levels" of Equivalence. The term covers too much ground for a
linear definition. At one level, the graphic level, the word
"Equivalence" pertains to the photograph itself, the visible foundations
of any potential visual experience with the photograph itself. Oddly

regardless of source, might function as an Equivalent to someone,

just to let you know that's all, Chris Jones.
