Camera
The light field controls. Each can be animated: the 
◆ 
at the right of a setting adds or removes its keyframes and moves between them (see Animation).
- Aperture: f/22 to f/0.5. Small apertures keep everything sharp; wide ones blur what is away from the focus (click the picture to choose what is in focus). Beyond f/2, the widest the camera can record, the blur is synthetic, using the depth map.
- Depth: how quickly things blur away from the focus.
- Smoothing: smooths the depth map, following the picture's edges.
- Lytro Desktop depth map: shown for photos imported from a Lytro Desktop library. On, the depth map Lytro Desktop computed (or the one edited there) is used for blur and depth masks; off, depth is measured from the light field as for any other photo. Lytro's map is usually the better one where the picture is blank or out of focus, such as a plain wall behind the subject.
- Show depth map: warm colors are near, cool colors are far.
How carefully the depth map is measured is set in Render (High quality depth map).
- Focus Point: where you last clicked; spread and tilt are centered there.
- Spread: a range of depth kept sharp on each side of the focus.
- Smoothing: softens the edges of that range, so blur builds up gradually.
- Blur: blurs the sharp range itself as well; Smoothing's gradual blur still builds up on top of it past the range.
- Show spread: tints what lies outside it, blue nearer and orange farther.
Tilts the plane of focus, like a tilt-shift lens: Tilt is the amount, Rotation the direction. Enabled turns the tilt off and on without losing the settings.
Viewpoint shows where the viewpoint is (drag on the picture to move it), as a share of the lens aperture across and down; Center is the middle.
Moving the viewpoint shifts every depth but one, the focus plane (or, with the aperture closed, the depth the camera focused on). Custom pivot and Pivot depth choose another depth to stay still.
The shape of out-of-focus highlights: Natural, Optical (softer), Circle or Blades, and Highlights to make bright points glow into bokeh balls.
- Blades (Blades shape): the number of aperture blades, 3 to 12, which is the number of sides of each bokeh ball.
- Oval (Circle shape): stretches the circle into an oval, like the cat's-eye bokeh near the edges of a fast lens.
- Rotation (Circle and Blades): turns the blades or the oval.
- Onion (Circle and Blades): concentric rings inside each bokeh ball, like those from aspherical lens elements.
