Film Noir puts a fixed diagonal gradient on your screen — solid black, sweeping up through white, then back to black — for a hard, graphic light-and-shadow split reminiscent of classic noir cinematography. It's a static gradient, not a live camera filter: it lights your face or a scene with real screen light, it doesn't process your video feed.
Before you start
- A screen you can angle, since the gradient runs diagonally and doesn't move on its own. A laptop, monitor, or tablet all work — what matters is the angle you point it at.
- Control over competing room light. A hard black/white split reads as "dramatic contrast" only when it's the dominant light source. Ambient room light flattens it back into a dim gray glow.
- A camera or recording app running separately, since this is a screen effect, not a video filter.
Set it up
- Open the Film Noir effect on the screen you want to use as your light.
- Position the screen off to one side, angled toward your face or subject — similar to where you'd place a hard key light, not a straight-on fill.
- Set Brightness. Start around 80–90; this is the only control that changes the output.
- Select Go Fullscreen so the gradient fills the whole screen with no browser chrome around it.
- Check your camera preview and move the screen or your position until the bright edge of the gradient crosses your face or scene rather than missing it entirely.
You'll know it worked when you see a hard, diagonal line between black and white on screen, with no color, blur, or movement — and that same edge shows up as a sharp highlight against shadow on camera.
To leave fullscreen, press Escape or move your mouse and select Exit Fullscreen.
What each control does
| Control | Range | What it changes |
|---|---|---|
| Brightness | 10–100 | Overall opacity of the gradient. At low values the whole screen dims toward black; at 100 the white band reaches full strength. It does not change where the bright band falls or how sharp the transition is. |
A color swatch also appears on the effect page, as it does for most effects. For Film Noir it has no effect — the gradient is always black and white regardless of what color you pick.
Common setups
- Dramatic video call moment. Angle the screen to one side at about 45°, Brightness 90–100. Good for a brief serious or dramatic beat in a call rather than the whole meeting — the hard contrast is fatiguing to sit under for long.
- Presentation section break. Put Film Noir fullscreen on a second screen or projector between slides as a visual palate-cleanser before a serious topic, Brightness 80.
- Moody background behind a subject. Position the screen behind and to the side of whoever's on camera so the gradient reads as background light and shadow rather than lighting their face directly. Brightness 60–70 keeps it from blowing out behind them.
- Photo or short video backdrop. Place the screen directly behind the subject facing the camera. Brightness 100 for the strongest graphic split; move the subject left or right to control how much black versus white shows behind them.
Troubleshooting
Changing the color swatch does nothing. This is expected — Film Noir's gradient is hardcoded to black and white and never reads the color picker. There's no setting that changes this; if you need a colored dramatic look, try Blue Hour instead.
The bright band is always in the same spot no matter what I do. There's no control for this — the gradient's shape and the position of the white band are fixed in the effect itself, not adjustable by any slider. To move where the bright light falls on your face or scene, move or re-angle the physical screen instead.
My screen looks almost entirely black. You're likely positioned toward one end of the diagonal, where the gradient is solid black, or Brightness is set low. Raise Brightness toward 100, and shift your screen's angle or your own position so the transition band crosses where you need light.
I expected the light to flicker or move like an old film, but it's completely still. That's correct — Film Noir is a static gradient with no animation or flicker built in. There's no setting to add motion to this effect.
The contrast looks weak or washed out on camera. Room light is competing with the screen. Dim or turn off other lights nearby so the black-to-white split on screen is the dominant light your camera sees.
On my single laptop screen, only part of my face is lit. With one screen, only a portion of the diagonal gradient is in frame at once. Angle the laptop so the bright band crosses your face, or use a second screen so more of the gradient is visible and usable.
Next steps
For a colored, animated take on moody lighting instead of a fixed black-and-white split, try Blue Hour or Moonlight.
