Hazer / Haze Machine / Atmospheric Hazer

Machine that produces fine, even atmospheric haze to make light beams visible and add depth to the image – uses oil or water-based fluid to create a subtle, long-lasting suspension of particles that enhances lighting effects without the thick clouds of fog machines.

What is a Hazer?

A Hazer is a machine that produces fine atmospheric haze. Unlike fog machines that create dense clouds, a hazer creates a uniform, subtle suspension of particles that makes light beams visible and adds depth to the image.

Today

The hazer is standard equipment for any quality-conscious production. It makes the difference between flat and cinematic lighting, between a documentary and a filmic look. Modern hazers are precisely controllable and enable subtle atmosphere that brings images to life.

From the crafts

Perspectives

Cinematographer

Der Hazer ist mein bester Freund für sichtbare Lichtstrahlen. Er macht Licht greifbar, fügt Tiefe hinzu und trennt Ebenen im Bild. Ohne Haze fehlt oft der Magic.

Director

Haze schafft Atmosphäre, ohne aufzufallen. Es macht Bilder filmischer, Räume tiefer, Licht sichtbarer. Ein subtiles, aber mächtiges Werkzeug für Mood.
