“Alta (White)” is an installation by James Turrell, created around 1967, that falls within the Light and Space art movement and is part of the Projection Pieces series. The artwork exemplifies Turrell’s innovative use of light to interact with spatial perception.
The artwork features a triangular projection of white light onto a corner of a room, creating a striking interplay of light and shadow. The luminous triangle appears to float, transforming the ordinary architectural space into a canvas for pure light. Turrell’s precise manipulation of light challenges viewers’ perception, inviting them to explore the relationship between light, space, and the sense of immateriality.
