About Us

Decagon is a contemporary photography platform rooted in Brooklyn, with an interest in what exists behind the photograph — the reason for making it, and the person who made it.

We see photography as a bridge between the seen and the unseen; a way of giving form to memory, wonder and imagination. Founded by John Manno and guided by Curator & Artistic Director Teona Machavariani, the gallery exists to celebrate diverse voices and to create accessible spaces where every photograph can shine.

Our mission is to support photographers who are expanding visual language and redefining the possibilities of the medium today. By showcasing a wide range of artists, we create space for deeper engagement with the ongoing conversation surrounding contemporary photographic practice.

Our Approach

We keep the door open.

Decagon is not tied to a single location. We keep the door open — building relationships with photographers wherever they are, and letting the work, rather than geography, decide who belongs in a show. Our focus is on attention and conversation: looking closely, taking our time, and staying in dialogue with the artists we exhibit.

What Guides Us

01AttentionWe look closely. We take our time with each photograph.

03IndependenceWe remain independent so that artists' voices remain free.
