The negative image has been of interest for some time- for example I have tried digitally blending abstract positive and negative video clips with a variety of blend modes. Recently I stepped back and tried something simpler – combining positive and negative projections of slides with the aim of creating a grey image..
I was interested in the way in which bodies or objects shadowing the projections could then create positive or negative images of their own, but what turned out to be as intriguing was the effect of cancellation – which is imperfect. This kind of faint grey image seeping through seems like a liminal image. An image on the threshold of visibility.
