During the 2010s, James Turrell continued his profound exploration of light and space, contributing significantly to contemporary art with installations that blend natural and artificial light in ways that transform perception and evoke introspection. His work from this decade is characterized by major projects and installations that further developed his themes of light, perception, and the experience of space. Roden Crater Project remained a focal point of Turrell's work throughout the 2010s. This ambitious project, transforming an extinct volcano in Arizona into a naked-eye observatory, epitomizes Turrell's dedication to exploring celestial phenomena and the viewer's engagement with the cosmos. Despite its long development process, with completion dates extended numerous times, the project has been a continual source of fascination and anticipation within the art world and beyond​ (Wikipedia)​. In addition to Roden Crater, Turrell's work in the Ganzfeld series exemplifies his interest in altering the viewer's perception through light. An example from this decade is Apani, presented at the 2011 Venice Biennale. This installation created an immersive environment where viewers experienced a complete loss of depth perception, a phenomenon known as the Ganzfeld effect. The work envelops visitors in a seamless field of color that shifts gradually, challenging their sensory perceptions and blurring the boundaries between physical and visual space​ (The Art Story)​. Another notable work from this period is Twilight Epiphany (2012), a Skyspace located at Rice University. This architectural installation uses LED lights to interact with natural light, creating vivid displays of color that enhance the perception of the sky. Designed to accommodate both visual experiences and musical performances, this work showcases Turrell's ability to merge art with environmental and sensory elements, inviting viewers into a space of contemplation and beauty​ (The Art Story)​. Turrell's installations from the 2010s, whether grand projects like Roden Crater or more intimate spaces like Apani and Twilight Epiphany, reflect his ongoing fascination with the ways light influences human perception. His work not only invites viewers to witness the interplay of light and space but also to participate in a profound, almost spiritual, exploration of sight and self-awareness. Turrell's installations are experiences designed to shift the viewer's consciousness, emphasizing the act of perception itself as a form of art​ (Art21)​. Through his innovative use of light and space, Turrell continues to challenge and expand the boundaries of visual art. His contributions in the 2010s further solidify his reputation as an artist who can transform ordinary spaces into extraordinary experiences, making him a pivotal figure in contemporary art.
