Redscale your Kodak BW400CN!


It may seem like a weird idea to redscale black and white film (that’s not sensitive to color either way), but read on to learn why it’s something you should definitely give a try.

Kodak BW400CN is a non-traditional black and white film for development in process C-41. Its back is, therefore and in difference to traditional b&w film, of an orange/brown tone.
My idea was to expose the film through its back, using it like a red or orange filter. To be able to do this, I reversed the film just like any other home-made redscales. If you have never done this, here is an excellent tipster on how to turn your ordinary film into redscale film.

Obviously, even when redscaled, Kodak BW400CN will still only display shades of grey. As with any red or orange filter in b&w photography, it will benefit though: contrast is higher, especially when photographing skies. Here are some of the results I got:

Please note that this tipster will not work for traditional black and white film! You’ll need film with a reddish/brownish back side. Also remember that when redscaled, any film will need more light. I recommend shooting reversed Kodak BW400CN at ISO 100-200.

    Nice idea, but watch out @meesterbrein as i've heard that Kodak have changed the base colour to be a lot clearer more like Ilford XP2.

    @simonh82 Thanks for the tip, but I got some old expired, so I don't think that's a problem.
