Composition
Written by Abin Alex and Anu Joseph.
Abstract
Composition is the selection and arrangement of elements within the frame of a photograph or a film shot. This guide sets out the main arrangements taught in visual literacy: the shape of the frame, the rule of thirds, visual weight and balance, diagonals, rabatment, triangles and the L shape. It traces the phrase rule of thirds to John Thomas Smith in 1797, and reports research on viewers' centre bias and perceived balance. Each method is treated as a heuristic, not a proven law, and the guide ends with when a maker may depart from it.
Keywords: composition; rule of thirds; visual balance; framing; visual literacy
What is composition?
Short answer. Composition is choosing what goes in the frame and where each thing sits, so that the viewer understands what you mean.
- A frame is a rectangle with an edge. Everything inside it is a choice, and so is everything left out.
- Composition has two jobs: to select the parts of a scene and to arrange them.
- The same scene can feel calm or tense depending on where the subject, the lines and the empty space sit.
- Viewers do not read a frame evenly. Size, brightness, colour and position all pull the eye, and the strongest pull leads (Arnheim, 1974).
- Painters worked on arrangement for centuries before the camera. A painter builds an arrangement. A photographer or cinematographer finds one and then moves their feet, lens or camera to fix it.
- Rules of composition describe arrangements that often work. They help you see, but they do not replace your judgement.
A photographer composes by changing position, height and lens. Stepping one metre to the left can remove a pole that seems to grow out of a head.
A cinematographer composes a frame that moves. The arrangement must work at the start of a shot, at the end, and while people move through it.
Cham tipBefore you press the button, look at the four edges of the frame, not only at the subject.
Cham taskPhotograph one subject in three different frames. Say which arrangement tells the story best and why.
Check yourself: What are the two jobs of composition?
To select what goes in the frame and to arrange it.
Should I shoot vertical or horizontal?
Short answer. The shape of the frame is the first composition choice. Horizontal frames suit wide scenes and vertical frames suit tall subjects.
- A horizontal frame is wider than it is tall. It is also called landscape. A vertical frame is taller than it is wide. It is also called portrait.
- Many still cameras use a 3:2 frame and many others use 4:3. Video usually uses a wider shape.
- Horizontal frames give a sense of width, calm and space. Vertical frames give a sense of height and focus on one subject.
- Phones and social video have made vertical frames common. A cinematographer may need to protect a shot for both vertical and horizontal delivery.
- Every method in this guide is a way of dividing a rectangle, so the shape of the rectangle comes first.
Turn the camera for a tall door, a standing person or a tree. Keep it horizontal for a crowd, a road or a landscape.
The frame shape is set before the shoot. If a film will be watched on phones and screens, plan one safe area that works in both shapes.
Cham tipShoot both shapes for important subjects. The wrong shape cannot be fixed later without cropping.
Cham taskPhotograph a standing friend, then a group of five. Choose the shape for each and give one reason.
Check yourself: Which frame shape suits a tall subject?
A vertical frame, also called portrait.
What is the rule of thirds?
Short answer. The frame is cut into nine equal parts by two vertical and two horizontal lines. The subject is placed on a line or at a crossing point, not in the centre.
- Imagine two vertical lines and two horizontal lines that divide the frame into thirds. The four points where they cross are the crossing points.
- Place the main subject, or the eyes in a portrait, on a line or at a crossing point.
- Put the horizon on the top line or the bottom line, not in the middle. Choose the top line to show more land and the bottom line to show more sky.
- John Thomas Smith used the phrase “rule of thirds” in 1797, for landscape drawing. He advised “to determine the sky at about two-thirds; or else at about one-third, so that the material objects might occupy the other two” (Smith, 1797). He was writing about the proportion of sky, land and water, not about a nine-part grid. He then extended the idea to light, shade, form and colour, and found the ratio of about two to one “a much better and more harmonizing proportion, than the precise formal half”.
- In a study of viewers watching video clips, gaze clustered near the centre of the frame, and this matched the tendency of filmmakers to put subjects there (Tseng et al., 2009). The centre is the default, and the rule of thirds is a way to move away from it. This does not prove that the rule makes a better picture.
- Most cameras and phones can show a thirds grid. Look for a setting named Grid or Grid lines in the menu.
For a portrait, place one eye on the upper left or upper right crossing point. For a landscape, put the horizon on a line.
Frame a person who looks to the right on the left line, so there is space in front of the face. This space is called look room or nose room.
Cham tipIf the subject looks or moves in one direction, leave more space in that direction.
Cham taskTurn on the grid. Take five photographs with the subject on a crossing point and five with the subject centred. Compare them.
Check yourself: Where does the rule of thirds place the subject?
On a line or at a crossing point, not in the centre.
What is visual balance?
Short answer. Visual weight is how strongly an element pulls the eye. Balance is the way the weights are spread across the frame.
- Larger, brighter, more colourful and more regular elements carry more weight. An element carries more weight the further it sits from the centre (Hübner and Fillinger, 2016).
- Symmetrical balance puts equal weights on both sides, as in a face or a building seen from the front.
- Asymmetrical balance puts unequal elements in different places: one large dark shape can balance several small bright ones.
- The seesaw idea: a heavy element near the centre can balance a light element far from it. The slides call this the fulcrum and lever principle.
- Radial balance spreads elements around a central point, like a flower, a wheel or a clock.
- Balance is not the same as equal. A frame can be unbalanced on purpose to create tension.
Check a picture by covering one half. Ask what the other half would need to feel finished.
In a two shot, the person who is lit brighter or placed nearer the edge changes the weight. Use this to show who has power in the scene.
Cham tipA small bright object far from the centre can weigh as much as a large dark object near it.
Cham taskFind one photograph in each balance type: symmetrical, asymmetrical and radial. Name the heaviest element in each.
Check yourself: What is visual weight?
How strongly an element pulls the eye.
What are the diagonal rule, the diagonal method and rabatment?
Short answer. These are three more ways to divide a rectangle. The diagonal rule uses lines from corner to corner and rabatment uses squares built on the short side.
- The diagonal rule imagines a line from one corner to the opposite corner and places lines or subjects along it. Diagonals tend to feel more active than horizontals and verticals.
- The diagonal method was devised by the photographer and teacher Edwin Westhoff, who dates it to about 2006. He holds that details important to the maker fall close to a 45 degree line drawn from a corner (Unique Photo, n.d.). The source notes that it is not clearly better than the rule of thirds.
- Rabatment starts from the idea that every rectangle holds two squares built on its short side, one at each end. Imagine folding the short side over onto the long side.
- You can put the active subject inside one square and leave the rest of the frame open, or keep the subject outside the square and let the square be empty.
- In a 3:2 frame the edge of each square falls at two thirds of the width, close to a thirds line. The two methods often give a similar result.
- No controlled study of the diagonal method or rabatment is cited here. Treat them as ways to look at a frame, not as tested rules.
Place a road, a railing or a river so that it runs along a diagonal from the lower corner. It leads the eye through the frame.
A diagonal across the frame, such as a staircase or a street, gives a sense of movement even when the actor stands still.
Cham tipA diagonal that starts at a corner draws the eye in. One that ends at a corner leads the eye out of the frame.
Cham taskPhotograph a road or a railing three times: horizontal, vertical and along a diagonal. Which feels most active?
Check yourself: What is rabatment?
Imagining two squares built on the short side of the rectangle.
How do triangles work in composition?
Short answer. Three subjects or points of interest form a triangle in the eye. A triangle gives stability and moves the eye from one point to the next.
- A triangle needs three points. They can be three people, three objects or three areas of light.
- A pyramid triangle has a wide base and a point at the top. It feels stable and calm. Painters of the Renaissance are often described as arranging groups in this way.
- An inverted triangle has the point at the bottom. It feels less stable and more tense.
- Triangles can come from converging lines, from symmetry, from a reflection or from repeated shapes.
- The eye completes an implied triangle even when its corners are cropped or hidden.
- A triangle also moves the eye in a loop, from one corner to the next, so the viewer reads the subjects in relation to each other.
In a family portrait, place the heads at different heights so that they form a triangle instead of a straight row.
In a three-person scene, put the actors at the corners of a triangle. Moving one corner changes who dominates the scene.
Cham tipLook for the third point. Two points make a line, and the third makes a shape.
Cham taskArrange three objects in a triangle and photograph them. Then move one so the triangle inverts and compare the feeling.
Check yourself: Why does a pyramid triangle feel stable?
It has a wide base and a single point at the top.
What is an L-shaped composition?
Short answer. An L shape appears when a vertical element and a horizontal element meet at a corner. It gives a feeling of rest.
- A wall and a floor, a standing person and the ground, or a window frame and a sill can all make an L.
- The vertical and horizontal lines are static. They give a feeling of calm, stillness and order.
- An L shape often leaves an open area of the frame. This empty space is part of the arrangement.
- L shapes can repeat, as in a door within a wall within a room.
- Combine an L shape with a diagonal or a curve when you want to add movement to a calm frame.
Use a doorway, a fence and its shadow, or a building corner as the L. Place the subject in the open part.
A person standing at the foot of a wall and looking into the open space reads as still and thoughtful. It suits a quiet scene.
Cham tipWhen a frame feels calm, check whether an L is holding it together.
Cham taskPhotograph one person using an L shape from the room where you live. Describe the mood in one sentence.
Check yourself: What mood does an L shape give?
Rest, stillness and calm.
When should I break the rules?
Short answer. Break a rule when the picture needs it. Rules describe arrangements found in many good pictures, and they were drawn after the pictures were made.
- A centred subject is right for symmetry, for formal portraits and for tunnels and corridors.
- Ask what the picture is about and whether each edge, line and gap helps that meaning.
- Research shows that viewers tend to look at the centre first (Tseng et al., 2009) and that they sense balance from the spread of visual weight (Hübner and Fillinger, 2016). It does not show one best place for a subject.
- Take the picture by instinct first. Then check the frame against the guides and change one thing.
- Table 1 lists each method with the source of the idea.
| Method | Geometry | Source of the idea |
|---|---|---|
| Rule of thirds | Two vertical and two horizontal lines at one third | Phrase used by Smith (1797) for the proportion of sky and land. The nine-part grid is the form taught today |
| Diagonal rule | Frame split corner to corner | Teaching tradition |
| Diagonal method | 45 degree lines from the corners | Edwin Westhoff, about 2006 |
| Rabatment | Two squares on the short side | Teaching tradition |
| Triangle | Three points joined | Long used in painting |
| L shape | A vertical and a horizontal meeting at a corner | Teaching tradition |
Table 1. Composition methods. Where the table says teaching tradition, no first source is cited in this guide.
Make a frame by the rules, then make a second frame that breaks one rule on purpose. Keep the one that says more.
Directors choose a centred frame for a formal or confronting moment and an off-centre frame for unease. The rule is a choice, not a law.
Cham tipIf you break a rule, know which rule it is and why.
Cham taskTake one photograph by each guide in this guide. Then take one that breaks them all and explain why it works or fails.
Check yourself: Why break a composition rule?
Because the meaning of the picture needs it.
Questions beginners ask
What is composition in photography?
It is the choice and arrangement of what goes inside the frame, so that the picture says what the maker means.
What is the rule of thirds?
It divides the frame into nine parts with two vertical and two horizontal lines. The subject sits on a line or at a crossing point.
Is the rule of thirds a real rule?
No. It is a guide and a starting point. The phrase goes back to John Thomas Smith in 1797, who used it for the proportion of sky and land in a landscape drawing. You can follow it, adapt it or break it when the picture needs it.
What is rabatment?
It is the idea that a rectangle contains two squares built on its short side. Subjects can be placed inside or outside a square.
Do cameras show a composition grid?
Most cameras and phones can show a thirds grid. Look for a setting named Grid or Grid lines.
When should I put the subject in the centre?
When the picture is about symmetry, order or confrontation, such as a formal portrait or a corridor.
