Has anyone processed K64 as b&W and if so what are the results like. Worth doing? I have some of it in the freezer and figured I'd let it stay and then at some point when I sold off a vintage camera throw in a period roll of film. But, the thought of processing it as b&w might be a better alternative. Also, how is it procesed as to developer, time, etc. and is the result a transparency or negative.
