Until a few years ago I processed my own Minox color films, C41 of course. They came out all right (ish), always having trouble with temperature and color shift. Anyways, I gave up doing this sort of thing, mainly because is too time-consuming and to be honest, I prefer to send my Minox color films to a lab abroad than to spend time and money for what I perceive to be a nuissance, for me that is.

Obviously, when one cuts and rolls his own Minox film, one stocks up on 35mm (usually bulk) rolls of bw and color negative. So, when stopped shooting color film, I suddenly had a good number of color films in my fridge, mainly Kodak Ektar 100, Fuji Superia Xtra, and other brands. Not hundreds of rolls, you understand, but some 20-30 in total. For a long time I was just keeping these in my fridge, when I thought why don’t I shoot color and develop it as bw negative? I did some in the past and it worked all right.
So, I run a test, involving a Minox IIIs and Agfa Color 200, processed it in Rodinal, and this is what I’ve got:
Not as bad as I would’ve thought they would come out. However, this is not the proper way of using color film, so I guess I will stick with the real BW film for now. But is always good to know that if in a pinch, I can use some color film for my Minox cameras, and why not, do the same for 35mm or even 120.
