Berens is notable for his unique and startlingly photorealistic painting methods, which he developed after teaching himself to paint with oils, in an attempt to emulate Old Master techniques. Although he was dissatisfied with the results he was getting with oil, he discovered that drawing inks, which remain fluid and mutable for up to two days, had a similar flexibility to oil paint. He explained, "When painting in oil, there are a lot of 'presents' you get from the medium. The way colors mix. The way the paint behaves, from your brush onto your canvas, how fast it dries, what happens if you force-dry it, etc. And oil is the medium that is closest to what I use. The amount of possible interference is at a maximum." When combined with a recent invention, plastic-coated inkjet printing paper, these fluid inks offered a new opportunity that had not been available to earlier generations of painters – an utterly smooth, semi-transparent surface designed specifically for the absorption of ink. He said, "I use plastic because it has no texture. I use the plastic on printing paper because it is extremely thin, and clever people have scratched their heads over how to keep the ink put." Beginning with pencil sketches and then moving into inks, Berens paints many multiple versions of a figure on
inkjet paper. Because the ink remains wet, he is able to work with it for some time – for example, dragging through it with a knife to create fur effects, or using a blow dryer to blur areas into soft focus. After a large number of small drawings have been completed, he chooses the portions of the figures he is satisfied with and cuts the paper into pieces, retaining the successful sections of the drawings. Peeling the paper backing off the inkjet paper, he is left with fragments of clear plastic bearing semi-transparent ink paintings. These fragments are then collaged onto board with bookbinder's glue, often six or seven layers deep, which creates an illusion of depth. He says, "I use the transparent layers because some things – such as skin, fur and light – can not be done in one layer (by me, that is). It's the same as real skin – the color and texture you see comes from all those semi-transparent layers of tones, and bumps and holes, that your mind blends into 'skin.'" Once he is satisfied with the composition, he marries the disparate elements together with ink and varnish, creating a layered assemblage which often includes hundreds of different elements. In 2011, to demonstrate this unusual technique, the artist recorded a time lapse video of the creation of his painting "Zadok the Deer." ==Publications==
