Rule of thirds and lighting — Animation for kids

The rule of thirds splits the frame with two lines across and two lines down into 9 boxes. Placing the subject on a line or where two lines cross (there are 4 crossing points) usually looks better than dead centre. In a frame 1920 pixels wide, the vertical lines are at 1920 ÷ 3 = 640 and 2 × 640 = 1280 pixels. For light, face a bright window or put a lamp behind the camera; a window behind the person turns them into a dark silhouette. Three-point lighting uses a key light (the main light), a fill light (softens shadows) and a back light (outlines the edges).

Creator's tip

Thirds and light — “put the subject on a third line, and light the face from the front”

  1. Thirds lines: width ÷ 3 and 2 × (width ÷ 3); the same for the height. 9 boxes, 4 crossing points.
  2. Good light falls on the face from the front; a bright window behind makes a silhouette.
  3. Three-point lighting: key light, fill light, back light.

Use it for: Framing photos and videos on any phone or camera, setting up a video call or a school presentation recording.

Worked example: 📸 A video frame is 1920 pixels wide. You split it into thirds with two vertical lines. How many pixels from the left edge is the first line? → 640

  1. The first line is one third of the way across.
  2. 1920 ÷ 3 = 640 pixels.

Check: 640 × 3 = 1920 ✓
