Kossakovsky utilizes a distinct direct-cinema style, relying on observational footage rather than traditional voiceover narration. The film is structured around the literal and metaphorical concept of the solstice—the "Baltic Sun" that never sets during the peak of summer.

Directed by the enigmatic Latvian-Russian filmmaker Aleksandr Volkov (a controversial figure often compared to Andrei Tarkovsky’s spiritual heir), Baltic Sun was financed as a co-production between Lenfilm Studio and a small Estonian production house. Volkov’s goal was radical: no voiceover, no interview, and no linear plot. Instead, the documentary would rely entirely on the "language of light."

The core of Baltic Sun at St Petersburg centers on open conversations with Russian naturists. Morozov’s camera steps away from the bustling urban center of St. Petersburg and moves toward the serene, wind-swept beaches of the Baltic Sea. 1. Personal Journeys into Naturism

The film explicitly highlights the systemic and social pushback experienced by the community. Interviewees detail confrontations with local authorities, the lack of official legal recognition for designated clothing-optional zones, and conservative public backlashes.

The film was released during the 300th-anniversary celebrations of St. Petersburg. While major TV specials like the St Petersburg 300th Anniversary Gala captured the high-brow opera and ballet at the Mariinsky Theatre, Baltic Sun documented a more grassroots, human experience.
