Lesson 3 of 8
Composition & Framing
Use the rule of thirds, headroom, leading lines and depth to make every frame look deliberate.
Learn it
The rule of thirds splits the frame into a 3x3 grid. Put your subject's eyes near the top line, not dead centre.
Leave a little headroom above the head, and looking room in the direction the subject faces.
Leading lines — roads, corridors, fences — pull the viewer's eye towards your subject.
Key terms
- Rule of Thirds
- A 3x3 grid guide; placing subjects on the lines or intersections looks more natural than centring.
- Headroom
- The space between the top of a subject's head and the top of the frame.
- Looking Room
- Extra space in front of a subject in the direction they face or move.
- Leading Lines
- Lines in the scene that draw the viewer's eye toward the subject.
- Frame Within a Frame
- Using doorways, windows or objects to surround the subject and add depth.
Fixing a Weak Frame
The same interview shot, improved in four moves.
- 1Before: Subject dead centre, huge gap above the head, a bright window behind them.
- 2Move 1: Lower the camera to the subject's eye line and cut the headroom.
- 3Move 2: Shift the subject onto the left third and leave looking room on the right.
- 4Move 3: Turn 45° so the window lights the face instead of blowing out the background.
- 5Move 4: Add a plant in the foreground for depth — now the frame has layers.
Checking thirds with maths (pseudocode)
pythonframe_w, frame_h = 1920, 1080
thirds_x = [frame_w / 3, 2 * frame_w / 3]
thirds_y = [frame_h / 3, 2 * frame_h / 3]
eyes_x, eyes_y = 990, 350 # where the subject's eyes are
def near(value, targets, tolerance=60):
return any(abs(value - t) < tolerance for t in targets)
if near(eyes_y, thirds_y):
print("Good: eyes sit on the upper third line")
else:
print("Recompose: tilt so the eyes land near y =", int(thirds_y[0]))Many cameras overlay this grid for you — the code just makes the idea explicit.
Try it
True or false? Judge these composition statements.
Placing a subject's eyes near the upper third line usually looks better than centring them vertically.
You should always leave a large empty gap above a person's head.
A subject walking left should have looking room on the left side of the frame.
The background does not matter as long as the subject is sharp.
Challenge
Take (or describe) three frames of the same person: one badly composed, one fixed with the rule of thirds, one using a frame within a frame. Explain what changed in each and why the last one has the most depth.
Pick whichever way suits you — every mode earns the same bonus XP.
