Drag Shutter

Flash + slow shutter

Fire a flash with a slow shutter and you get two pictures in one, a sharp one frozen by the flash and a blurred one from the light in the room while the shutter stays open. Drag Shutter does that to your picture, with the camera dragged sideways, zoomed or spun.

What it's like

Club and concert photos where the dancer is crisp but the lights behind smear into streaks. Photographers swing, twist or zoom the camera during the exposure on purpose. The flash freezes whatever it lit, and everything else turns into motion.

When to reach for it

  • Nightlife and concert energy on a still picture.
  • A rush of speed. Zoom pulls everything toward the center.
  • The full party look. Put a Flash under it, so the lit subject stays sharp and the room smears.

How it works

Drag Shutter blurs the whole frame, then keeps the brightest parts sharp, the way a flash lights the near subject brightest. Lights caught in the blur streak brighter, and a faint offset copy sits in the blurred parts, like a second exposure.

Controls

6 controls in 2 sections, in the order Tune shows them.

Motion

  • SelectMotion DirectionalZoomSpin

    How the camera moved. Directional is a sideways drag, Zoom rushes toward the center, Spin twists around it.

  • Hero knobBlur 0 to 100 · rests at 50

    The hero. How far the camera moves while the shutter is open.

  • KnobAngle 0° to 180° · rests at 0°

    Directional only. Which way the drag goes.

Flash

  • KnobSharp core 0 to 100 · rests at 45

    How bright a part must be to stay frozen sharp. Low keeps most of the picture crisp. High freezes only the brightest parts and lets the rest smear.

  • KnobTrails 0 to 100 · rests at 55

    Lights in the blur streak brighter, like light trails.

  • KnobGhost 0 to 100 · rests at 30

    A faint offset copy in the blurred parts, the second exposure.
