Built on CoreMediaIO

Your webcam deserves
more than software filters

CamTune adjusts exposure, focus, white balance, and more directly on your camera's hardware — not through a filter layered on top of the picture.

The problem

Software filters fight the picture. CamTune fixes it at the source.

Most "webcam" apps sit between your camera and your calls, reprocessing every frame to fake a better picture — burning CPU the whole time. CamTune never touches a single frame. It just tells the camera itself what to do.

Software filters

Reprocess every frame

Brighten, sharpen, and color-correct in software, after the sensor already got it wrong — spending CPU and battery on every single frame, forever.

CamTune

Sets it once, on the camera

Every control lives on the camera's own chip. Set it once and it's right for every app that uses the camera — no CPU spent, no filter to break.

Powered by CoreMediaIO

Every slider talks straight to your camera.

CamTune reads and writes your camera's real hardware controls through macOS's own CoreMediaIO framework — the same path Apple's UVCAssistant extension already uses. Drag a slider, and the change shows up instantly in FaceTime, Zoom, OBS, anything already looking at that camera.

Set it once

Dial it in, then forget about it

Save exactly how a camera should look as a profile, switch back to it in one click, or have it apply automatically the moment CamTune starts.

  • A profile per cameraEvery camera you own keeps its own set of saved looks — nothing gets mixed up when you switch.
  • Apply at startMark a profile to load automatically the next time CamTune launches — no manual step, ever.
  • Menu bar quick switchChange cameras or profiles from the menu bar, without ever opening the main window.

CamTune never sees your video

It only talks to your camera's hardware controls over CoreMediaIO. No capture session is ever started, no frame is ever read — CamTune couldn't show you your own video if it tried.
