My favorite example of a synecdoche is "the 'suits' walked into the room".
A photograph is a thing. Just like Magritte's painting of a pipe is a thing but not a pipe. But these photographs are paintings and not photographs. They are records. They are not ships nor painted over weathered graffiti. I often see this way-- one or two steps out from the thing that it is. I need this in my life for some reason.
