Daniel Demoustier is principally known for his long-standing career as a Belgian war correspondent and documentary maker, recognized for both frontline journalism and creative media productions across global contexts. He worked as as a freelance cameraman, director of photography (DOP), producer, and director for major international broadcasters and media outlets, including the BBC, ITV (ITN), NBC, Channel 4, Al Jazeera English, and Belgian networks.

His work covers reporting from numerous war zones and crisis regions worldwide, such as Afghanistan, Bosnia, Darfur, Gaza, Haiti, Iraq, Kosovo, Libya, Mali, Syria and Ukraine.

Beyond frontline journalism, he has produced documentaries, corporate and educational films, and engaged in art-related multimedia projects, corporate events and music videos.

His archive of over 20 years of war reporting has inspired artistic works such as Unfolding an Archive, a performance by his daughter Zoë Demoustier, reflecting on his visual legacy and Orestes in Mosul, a film about Milo Rau's theatre production in Mosul.
