Cool effect

Xenon Fog

Xenon Fog is a colour grade in FRCTL, the browser VJ studio. Bright white-blue haze with softened midtones.

Runs live on video, images, a camera or generated art. Stack it with any other effect, and route LFOs, envelopes or any of ten audio bands to its controls so it moves with the music.

What Xenon Fog does

Keeps more of the picture than the other Cool grades. It tints the source blue and lifts its blacks, lays a steel-blue to icy-white fog gradient over it, then adds a blue-white haze to the upper mids and bleeds out some saturation. Fog sets how much gradient covers the tinted source, Haze adds the glow and grey, Blend scales the lot.

Using Xenon Fog

Where it works: Smoke-machine atmosphere on a live set, winter or early-morning shoots and slow ambient intros. Faces stay recognisable because source detail survives underneath, which also makes it a sound base under heavier effects.
With the music: Nothing inside reacts to music. A beat-triggered Envelope on Haze gives each downbeat a quick white bloom, and B2 sub bass on Fog thickens the gradient through drops.
Starting point: Blend at centre, Fog a quarter, Haze three-quarters, then lower Fog until dark lines come back through.

Controls

Blend: Strength of the filter vs source.
Fog: Fog layer mix vs cool-tinted source.
Haze: Additive haze and desat punch.
