Exhibition: Turned Toward the Firmament – Joachim Froese

Joachim Froese presents a series of downloaded NASA photographs of Mars translated into unfixed salt prints. Washed in a strong solution of sodium chloride the prints are stabilized but not permanent. They remain sensitive to UV light and are destined to change and eventually disappear.

    That is an interesting idea. Presumably, the NASA photographs are in the public domain.

    A question: ‘how do you translate the NASA photographs into a salt print that is then exposed in indirect sunlight within a frame?’

      Howdy Gary,

      I like this idea, especially the historical text on Joachim`s website. I should imagine this would be a fairly familiar process for those working with digital negatives. He says that he downloads the photographs which for these prints of a modest size is absolutely possible. The rest is, as they say, contact printing!

    Thanks very much Matt, David and Ellie for that information. It is much appreciated.

    Is this the process to make an inkjet negative?

    Open your downloaded image in your photo editing software, convert to greyscale to make the negative, flip the image horizontally, invert the image, place a sheet of Digital Transfer Film in your inkjet printer, then print. Once the negative is dry you place the negative face down on your paper to make your print.

    Have I got that process right?

      Gary, there are dedicated programs for making digital negatives, but yes that is correct.
      The process of making digital negatives has become better and better. Not long ago ‘alternative process’ photographers wouldn’t dream of using digital negatives, now almost all use the process. So much so that large format cameras larger than 4×5 or 5×7 are being used less and less due to the ease and quality of large format digital negatives.
