Lightfield Studies: Lightfield Study #1

Fifty-six unique artworks, each with 20 x 16 inch prints, from Lieberman’s daily sketching practice.

Some came out of the same mathematical rules as each other and arrived at very different forms. Others vary by just a small change: a shifted angle, a different curve, an adjustment to how light bends or accumulates.  

Each stands on its own, but together they reveal an ongoing process of exploration in code.

EXHIBITION TEXT

Zach Lieberman makes photographs of math.

The works begin with observation. Lieberman studies the ways light interacts with different materials, from metal and lenticular lenses to iridescent film.  He translates these observations into code, where behaviors can be exaggerated, combined, or pushed beyond what physical materials allow.

The geometry is simple: lines, grids, boxes, and curves. The complexity comes from how light interacts with these forms. Here, light takes on qualities of a physical material. It appears to have edges, volume and weight, without solid boundaries. It leaks and blends. Light becomes the object itself.

The eye completes the work. Some of what we see comes from the image itself, and some from our own perception: vibrating edges, colors that seem to separate, and forms that linger like afterimages. These effects aren't just part of the image. They happen as we look.

For more than a decade, Lieberman has maintained a practice of making daily sketches in software. Across thousands of experiments, ideas recur, mutate, and branch into new directions. The fifty-six smaller works offer a glimpse into this ongoing process, while nine large prints bring selected experiments to a new scale and a series of animations unfolds them over time.

Abraham Palatnik and Gottfried Jäger offer important historical precedents. In the 1950s, Palatnik used mechanical systems to compose light, color, and movement. In the 1960s, Jäger used photographic rules to make images without depicting the visible world. Like these artists, Lieberman uses systems to shape light, but computation allows him to go further: rewriting the very rules that govern its behavior.

Nothing here was ever lit. A photograph records light from the physical world. These works record light that never existed, behaving in ways real light cannot. Each work is an investigation of what light could be.
