I am trying to figure out what type of photography gives the silver (reflective) twinge to photographs like old historic photos. I have started looking in to wet plate photography (I would assume it is some kind of wet plate) and quickly figured out there is a ton of info out there for it. This is a good thing if you know what to look for, but I'm not sure where to begin looking. I specifically want to create some of the silver (reflective) photos. Does anyone know what this specific type is called or maybe have a good reference (book, website, etc.) I should look at? Thanks in advance.
