    Cross process Kodachrome as B&W

    I have searched the forum but I didn't really find what I was looking for :-(


    I want to try developing Kodachrome in B&W chemicals and printing onto colour paper (it'll look similar to a cyanotype?), just for the craic really. However, I haven't exactly found step by step instructions on how to do this. I quite regularly process B&W film so this is no problem, but I haven't been able to find information on the exact process.

    I've read that the anti-halation layer needs to be removed (pre-soak?) and that a residual coating needs to be removed after processing. Is this correct? Doesn't the residual coating give an unusual texture to the print if it's left on? I would probably use ID-11 but would use another developer if it is better suited (although, image quality isn't too important).

    Any help would be appreciated.

    No residual coating must be removed from the film after processing.

    The anti-halation layer is removed by wiping the back of the film with a sponge soaked in sodium carbonate solution. Then rinse the back with a damp sponge.

    Just process as B&W and you will get a yellow B&W negative.

    Thanks. Have you got any advice about development times, or is it good enough to process as Plus-X rated at 64 ISO?

    Sorry, I have no idea what development time to use. I've never tried it.

    Someone else may have that information. You might try a small piece of the leader and see how long it takes to develop to dmax. That would give you an estimate.

    Hi, sorry to bump this thread, but my question is related.

    I believe I have maybe 10 rolls of Kodachrome 64 in storage, but I won't be able to get to them until around February or March 2011. Am I to understand that Kodachrome can be developed in regular D-76? What kind of results would I get from just standard processing?

    Caffenol to the rescue!

    Search out the caffenol blog at Blogspot.com, and read all of it.

    Kodachrome comes out kinda weak and grainy, but there definitely is a B&W negative.

    I have a partially exposed roll sitting here, from an old camera bought on Ebay, but I really look forward to allk the durn cheap KC thats gonna be dumped on the market in about a months time!

    AH, times and stuff:

    Caffenol C-M :

    Water to 1000ml
    Washing soda (Na2CO3) 54 gram
    Ascorbic acid (vitamin C POWDER) 16 gram
    Instant coffee (brazero or pure black) 40 gram

    Mix in the order given and let bubbles stop between Vit C and coffe, let stand for 15 minutes.

    Develop at 15 minutes at 20 centigrade.

    But read the blog, there is a better explanation!

    i have crossed processed other chrome films, but not kodachrome ..
    and i also used a strong brew of caffenol. it was about 3x the strength of
    the conventional caffenol recipe ( around 8 tbs robusta-heavy /cheap instant coffee, around2 tbs washing soda, and around2tbs powdered vit c )
    i don't have any convention about how i mix them, usually it is coffee first, then washing soda then vit c ...
    i also add some print developer, i use ansco 130
    ( it has glycin, potas bromide, carbonate, metol+hq as well )
    it is like dektol kinda-sorta but with glycin if you have dektol or a similar developer whatever else you have might work as well
    ... i add it in around 1:10 - 1:12ish
    it doesn't sit for long, just as long as it takes to pre-wet my film.
    the film is stand developed for about 25mins
    i water bath/pre wet tap bubbles off the film, first then after 2 mins
    add the instant coffee mixture.
    i tap the bubbles out and that is the only agitation i do.
    water bath, then fix ...

    i say " around " for my measurements because i eyeball measure my ingredients

    i've never shot kodachrome or cross-processed anything but straight e6 / c41 ..
    so i don't know if it will develop the same way ... but a strong brew and stand develop always works for me ...

    please be advised the uploads are part of a hybrid thing ..
    ... i removed the hue that plagues cross processed slide film.

    YMMV


    good luck !

    I have dug up 8 rolls of Kodachrome 64. They've been in the freezer since I bought them 3 years ago.

    I'd like to shoot it as B&W, what ISO would folks here recommend? 64? 50?
