C-41 Color film processed in D-76 sucessfully

Discussion in 'Darkroom Developing and Printing' started by Chris Camporeale, May 8, 2004.

  1. Hello,

    For all of those people out there looking to process color C-41 film
    in B&W Black and white chemicals, here is what I did:

    I took kodak gold 400 and developed it in D-76 for 13.5 mins with
    agitation every 30 seconds.
    The negs came out perfectly except for the classic brown/red tone that
    color film has. Decent B&W prints can be made if you have a dichroic
    enlarger and add enough cyan and magenta to make it look white.

  3. What does such processing achieve that conventional or
    C-41 black and white cannot?

  4. Archival stability, for one. Conventional colour processing strips the
    silver image and replaces it with dyes. Black and white processing leaves
    the silver image intact.

    I have no idea how useful the process is - you'd be better to shoot black
    and white film than colour if you want black and white images - but it does

    Actually, I do know of one usage. Very old films often process better as
    black-and-white images than as colour. Film Rescue International processes
    C-22 and K-11 (-12?) as black and white for this very reason. The odds of
    getting usable images are greatly enhanced.

  5. One, it may allow use of very inexpensive one-time purchases of film
    (cleaning out the photo department of a closed drug store, say) without
    paying a lab to process (and without dealing with the vagaries of home
    C-41). Two, it might produce a particular effect someone wants to see
    (with my scanner and software, for instance, it's possible to get a
    pseudo-color effect from a monochrome image produced with HC-110 or
    similar, on color film stock, by telling the scanner it's looking at a
    different brand or type of film to induce an incorrect correction for
    the base color). Three, it might be the preferred method of recovering
    images on found film, compared to commercial processing and being unsure
    what the lab techs will see (one just never knows, these days, what will
    be on a roll of found film). Four, it is the only reliable and
    economical way to recover images from very old color film (C-22, K-12,
    E-3, etc.), and it's better to practice on something other than the
    irreplaceable roll from Grandma's camera.

    I looked at it because I can get ISO 400 C-41 film for less than fresh
    Tri-X -- but then I found a good deal on bulk Tri-X and haven't needed
    to pursue things. Still worth knowing, just in case -- in these days of
    waning photographic options, I can make my own developers and fixers,
    but I might be able to buy color film longer than B&W. Or maybe not...

    I may be a scwewy wabbit, but I'm not going to Alcatwaz!

    Opinions expressed are my own -- take them for what they're worth

  6. You can pickup color negative film for cheaper than BW films. Freestyle sells 100ft for 9.99.
