I can answer that one: a tintype developer for liquid emulsion needs to essentially fog the gelatin silver layer so it is brownish/yellowish and shows up on the black plate. Thus the addition of fixer to the developer. It still requires fixing.

I figured out a recipe that would use dektol, sodium sulfate, and ammonium thiocyanate but am not quite sure whether the proportions have to be within an exact gram amount or not.
