The Deep Dark is an art installation that asks "why do we fear the dark?"

The Deep Dark is a recurring art installation by Caitlind Brown and Wayne Garrett:

To develop the installation, the artists conducted interviews, asking: why do we fear the dark? Is darkness a presence or an absence? What separates real fears of nighttime from imaginary fears of things we cannot see? By unearthing commonalities between interviewed participants, a loose narrative emerged, exposing a collective insight into our human relationship with the deep dark.

The Deep Dark uses domestic doorways as an entry point, inviting you to move through ghostly architecture. As you pass through each frame, you are blinded by intense white light that overexposes your eyes. The darkness beyond the frames is magnified to blackness, much darker than before. As your eyes adjust to the dark, the next illuminated doorframe becomes visible in the distance, beckoning you onward. From an outward perspective, as viewers step through the gates, they disappear completely. Intended to impose artificial light into the wild darkness, The Deep Dark is light by which the darkness grows darker and disillusions the night.
