Ah, I hadn't thought of a primitive video recorder - that would explain it then.

Quote: "Also doesn't specifically mention by Dishonored 2. Might mean before D1."

I took Pauolo's statement of "Cameras called Silvergraph have just been invented by the time of Dishonored 2" to mean like JUST invented shortly beforehand. If he meant it different or I misread his post, then I apologize.
