"Event Horizon" is the fourth book by aerial photographer Kacper Kowalski. It reveals the most intimate parts of the artist's soul, showing his introspective approach to nature and the discovery of his vulnerability and feelings through flying in a gyrocopter around Poland, the author's home country. "With the onset of winter, I embarked on a journey in search of harmony. Driven by instinct, I ventured further and further, until I exceeded the limits of rationality," says Kowalski.

"Event Horizon" is both a standalone book and a companion piece to his previous book, Arché. Both projects were made in similar locations and physical conditions. Despite their similarity, they are very different on a meta-level.

The book "Event Horizon" was awarded first prize in the nature category in the American International Photography Awards IPA competition in 2023.
