    Hello,

    Looking for help on Cyanotype. I've followed the instructions, watched tutorials and done successful Cyanotypes years a go at University. However upon trying currently it just is not working.

    I'm mixing the chems, equal parts and painting the paper and then leaving to dry. I'm then placing a digital negative over the image and using a UV lamp to expose the image. However the resulting 'imprint' remains yellow with no signs of blue, and upon rinsing in water the emulsion just runs off the paper.

    Before it runs I can see the image on the emulsion in decent detail.

    So far I have:

    Changed lamps to different UV wavelengths.
    Changed Paper
    Varied or Extended the Exposure times.
    Changed the Ph of the water used.

    All to no avail.

    Any help would be much appreciated.

    I think you are underexposing.

    We've (well, mostly lazy lobster) has just done objects like leaves, keys, and twigs. Once I get this printer replaced, we'll try some photos.

    @Reece Hudson: I'm with compur and thinking exposure.
