fos/4 takes the most desired features of a standard incandescent Fresnel and adds in the nuanced color mixing, smooth fades, and LED technology of ETC’s other professional grade fixtures. With fos/4, you get a true Fresnel with an LED engine, not the other way around.
With the addition of a deep red LED, we render skin tones, sunsets, and moody saturated scenes better. We’ve reached further into the corners of the CIE color space to grab the deepest red — a red that is essential to accurately capture the warm glow of firelight, romance at sunset, the most nuanced skin tones, and the truest whites.
Predictable nuanced color from reality, to the camera, to the screen. See how fos/4 transforms how you work each day.
