Just a complete break for a few days from oil painting, in order to play with something new. I have read several articles on ink and gouache resist techniques but never tried them. They seem to work best with strong shapes and structures, so I dug out a photograph of Glastonbury Tor, famous English landmark, and did a drawing on watercolour paper.
The technique then requires the artist to cover over those areas that need to be white in the final picture. The covering is done with thick white gouache paint. Once this is thoroughly dry, the whole picture is painted over with black india ink (waterproof). This must also be left to dry.
When ready, the paper is placed under a cold flow of water and the gouache paint, although covered with ink, will begin to drift off the paper. The ink on top of it will also flow off. Areas that were not painted with gouache will be black ink. However...
The random nature of this process shows that some areas of white will be flecked with black. Also, some thinner patches of gouache will not totally resist the ink and thus may turn quite dark. In my picture, the black patch on the right hand side happened because I did not paint thickly enough with the white gouache.
The overall effect is one reminiscent of a woodcut. The image is stark black and white. It is possible to add colour but the black ink will resist most water-based paints. You might paint over it with thick acrylic, however.
I decided to leave this image alone and not add colour. I may do a second one....it will never come out the same as the first...and try adding colour as an experiment.
A few days ago I carried out another wash for a different subject, which is more complex. It is testing the ability to place black and white areas in the image; sometimes I get it right, sometimes not. The images are far more graphic than "standard" painting; they may help to create new painting ideas for me.
Good fun in between my usual oil paintings.
