Am I crazy? Possibly, but certainly curious. I tried a number of search parameters here on APUG and I mostly got a lot of posts about using color neg films in conventional developers. I'm wanting to do the opposite, but I really don't like reinventing wheels or doo-hickies if I can avoid it. I'm hoping someone here has gone before me. Why do you want to do this, I hear you reasonably ask. Well, it was known almost a century ago that a certain developer had the ability to make very, very fine grain. Acutance sucked. These are the para-phenyenediame developers, precursors I believe, to the modern color developers. So, the first chemo-hurdle is, am I wrong? The other reason I"m intrigued with this concept is that, let's face it, B&W developers pretty much stagnated years ago. Yet, at least up until digital putting the wooden stake in the heart of C-41 processing, C-41 got all of the attention of the Big Minilab Boys. Surely they kept tweaking the chemistry. Finer grain, better acutance. Anyway, what I"m hoping for. Obviously, no bleach. Has anyone tried this?
