North of the Sea documents Guillaume's photographic expedition along Norway's coastline, as he explores his wife's ancestral homeland. The project's defining moment came during a family crab fishing trip when he released a small bait fish back to the sea—only to watch a seagull immediately seize it. This encounter revealed the complexity of natural systems and the unintended consequences of human intervention. The series captures Guillaume's sway toward restraint: observing rather than manipulating, documenting rather than directing, finding stillness in simply what unfolds.
