Kinetic Umbra Exploration of Space

Long Exposure Photography

Having practiced many styles of breath and movement, I want to explore what shapes the practices leave in space. My intention is to record the full range of a flow in one exposure to discover what that might reveal about the practice and about the body. The act of recording these images is an especially intensive in-the-body experience as the movements need to be consistent throughout the entire exposure. In addition, these photographs take place in complete darkness where I am blind. This acts to deepen the practice, timing, breath, and balance.

Limited edition giclée prints are available square in any size from 12″ x 12″ to 36″ x 36″ on a clear acrylic substrate. Editions are limited to 18 per image in any size. All prints are shipped with standoff mounting hardware unless other mounting options are specified. For larger sizes, installed work or other information, contact me.


Kinetic Umbra

uses the human form recorded in time and space via a single, long-term exposure digital photograph, to reveal hidden organic geometry and elemental shapes.

The Artists

Concept and Performance:

Arthur Grau has worked in design, performing, and media arts throughout his life. Themes that arise in his work include meditations on natural forms, public participation, and representations of cultural symbolism. Early works include multi-media graphics as Enzyme and music recordings and performances with ‘Missed in Diary’ and ‘Dissolve’. Later, under the name Circa, his work centered on two-dimensional design and three-dimensional installation. Through intricate cut paper art, he explored geometry, symbolism, and meditation. Using labyrinth installations and experiences, ‘Deeper Jester’, ‘Man-dala’, and ‘Mojave’ he engaged the public to explore self and surrounding in new ways. ‘Mojave’ is now made visible by Google Earth.
