Digital negatives

May 26, 2017  •  Leave a Comment

I have made digital negatives in the past, for example in order to make gum bichromate prints or occasionally cyanotypes. Recently I have tried making some digital negatives for more conventional printing.

Large digital negatives printed on transparency film by a laser or inkjet printer (being sure to have the right transparency film) can make for some straightforward contact printing in the darkroom. As a teaching tool this can give a partial introduction to darkroom work for those who have never use a film camera. 

What I wanted to do recently was to produce lith prints with an infrared film appearance. Having gone out to the Forest of Saint Sever I found, more or less by chance, a site I had not seen before. With good sunshine and young leaves on the trees it cried out for IR treatment, but I was without my film camera or IR film. A simple digital compact allowed me to get a few pleasant shots. Some of these I converted to simulation IR black and white files and printed a few large digital negatives for contact printing.

This images was originally taken on a simple digital camera. The file then underwent resizing and conversion to black and white - simulation of IR - in Photoshop elements. A digital negative was then printed on a laser printer and that used to make a contact print in the darkroom. The image was printed on Foma 331 (RC) in lith developer.
Of course the print had to be scanned to get it back to digital form to allow it to be posted here.

This is probably the best example of the few that I printed. I need better transparency paper to make some more precise negatives, but this give an idea of what can be done.

PS I have cleared out a few pictures that I felt did not need be on the site, and a couple of galleries. More tidying up should follow but it could mean a few links from other blog posts have been lost.
