Natural Light Photography: Tips for Beautiful Images

Natural light photography means making pictures with light you did not make: the sun, the sky, cloud, shade, and the light coming through a window. You cannot move the sun or switch it off, so the skill is choosing: when you shoot, where you put the subject, which way you point the camera, and what you add or take away.

It matters because light decides more of a photograph than any setting does. The same face, building or field can look flat, harsh, warm, cold, dramatic or gentle depending only on where the light comes from and how big its source is. Learn to read daylight and you can predict a picture before you lift the camera, and fix a bad one by walking ten steps or turning your subject a quarter turn.

Four questions to ask of any light

Every lighting situation comes down to four things. Name them each time you shoot.

• Where does it come from? In front of the subject, beside it, behind it, or above it. Direction decides where the shadows fall and so how much shape and texture you see.
• How big is the source, seen from the subject? A source that looks small from where the subject stands gives crisp shadow edges; a big one gives gradual edges. That is the whole of hard versus soft light, and it is about apparent size, not brightness.
• How bright is it? Brightness sets your exposure, and the difference in brightness between the lit side and the shadow side sets the contrast.
• What color is it? Low sun is orange, light from blue sky is blue, light bounced off grass or brick takes on green or red. Your white balance decides how much of that color you keep.

The sun is tiny in the sky, about half a degree across, the width of a pencil held at arm’s length. That is why a clear day gives hard light. Cloud, haze, a big window or the open sky above a shaded doorway each turn that small source into a large one, and the light softens. Quality of light covers these terms in more depth.

Direct, diffused and reflected daylight

Daylight reaches your subject in three ways, often all at once, and it helps to separate them.

Direct light comes straight from the sun’s disc. It is hard, bright and directional, and it changes color with the sun’s height.

Diffused light has been scattered on the way: by cloud, fog, haze, or the atmosphere itself, which is why the clear sky glows blue. The source becomes large and the light becomes soft. On a sunny day the subject’s shadow side is lit mostly by diffused skylight, and that is why shadows on a clear day are bluish. Diffused light has more on how scattering works.

Reflected light has bounced off something before it reaches the subject: a pale wall, a pavement, sand, snow, water, a lawn. It is the free fill light of natural photography, and it always carries the color of the surface it bounced from. A face beside a red brick wall picks up a warm cast; a face over a green lawn can look slightly sickly. Notice the surfaces around your subject, not only the sky.

Read the light from any shadow

A shadow tells you three things about the light, and you can read them in a second, even through the viewfinder.

1. Its edge tells you how hard the light is. A razor edge means a small source: clear sun. A blurred edge means a large one: cloud, open sky, a window. No visible shadow at all means the light is coming from everywhere, as under heavy overcast or fog.
2. Its direction tells you where the light is. The shadow points away from the source. If shadows run toward the camera, you are shooting into the light.
3. Its length tells you how high the sun is. The lower the sun, the longer the shadow, and the warmer and more directional the light.

The length rule is simple geometry. On flat ground, an object’s shadow is its height divided by the tangent of the sun’s elevation. A person 1.7 m tall casts these shadows:

Two checks you can do on the spot: if your own shadow is longer than you are tall, the sun is below 45 degrees; if it is twice your height or more, the sun is below about 27 degrees, which is low enough for good side light on faces and buildings. A fist held at arm’s length covers roughly 10 degrees of sky, so a sun one fist above the horizon is in the warm, long-shadow band at the top of the table.

Want to make the shadow itself the picture, not just a clue? Shadow photography works with shadows as shapes and subjects.

How daylight changes from sunrise to sunset

Because the sun’s height decides shadow length, contrast and color, the time of day is the biggest single control you have over natural light. The sun moves about 15 degrees across the sky every hour, and how fast it climbs depends on your latitude and the season.

Golden hour. When the sun is within about 6 degrees of the horizon, its light travels through so much atmosphere that much of the blue is scattered away. What gets through is warm, and it arrives from low down, so it lights the fronts of things rather than their tops and throws long shadows across the ground. It is called an hour, but its length is set by sun height, not the clock: about 25 minutes near the equator, roughly half an hour to 40 minutes at mid latitudes around the equinoxes, and far longer in high-latitude summers. The golden hour calculator gives the times for your location, and golden hour photography covers how to use it.

Golden hour light is often called soft. On a clear evening it is not: the sun is the same half-degree disc and its shadows are still sharp-edged, as on the buttes above. What changes is contrast. The atmosphere dims the direct sun far more than it dims the sky, so shadows get relatively more fill and the gap between lit and shaded sides narrows. If you want truly soft light at sunset, you need haze or thin cloud in front of the sun.

The rest of the day. As the sun climbs, the light becomes whiter, brighter and more overhead. Shadow sides darken compared with lit sides, eye sockets fill with shadow, and landscapes lose the long shadows that showed their shape. This happens when the sun is high, not at a fixed clock time; in a high-latitude winter the sun may never climb high enough for midday to be a problem.

Test your eye: one of these two photos was taken in golden hour and the other with the sun high. Pick the golden hour one, then read how the light gives it away.

Which photo was shot during golden hour?

A B

Blue hour. Once the sun is a few degrees below the horizon there is no direct light at all. The whole sky becomes one large, soft, cool source, and the light is dim enough that artificial lights in a scene balance with the sky. Blue hour photography covers the exposures this needs.

The color of daylight across the day, in kelvin, as a rough guide. These numbers vary with haze, cloud and latitude, so treat them as directions, not settings:

See color temperature for how the kelvin scale works and why higher numbers look bluer.

To see what those numbers do to a picture, pick a light below, such as sunrise, cloudy or shade, then set the camera white balance and watch the colors come right when the two match.

Choosing the direction of daylight

You cannot move the sun, but you can move almost everything else. Turn the subject, walk around it, or come back at a different hour, and you choose which of the three main directions you get.

Front light (sun behind you) puts the shadows behind the subject where the camera cannot see them. Colors are bright and detail is clear, but form goes flat, and a person facing the sun squints. “Keep the sun behind you” is snapshot advice that trades shape for safety.

Side light (sun roughly 90 degrees to your line of sight) lights one side and shadows the other. Shadows now fall where you can see them, so surfaces show their texture and round things look round. Low side light is the classic landscape light, because every ripple, stone and blade of grass casts a shadow the camera can see.

The two photographs below show the same idea at a glance: one with flat light, one with side light.

Which photo uses more directional light?

A B

Backlight (sun behind the subject) puts the side facing you in shadow and outlines the subject with a bright edge, a rim light that separates hair, leaves and grass from the background. Translucent things, leaves and petals especially, glow. The cost is exposure: the bright sky fools the meter into making the subject dark. Expose for the subject and let the sky go light, add fill with a reflector, or expose for the sky on purpose and make a silhouette.

Want to plan which way the light will come from before you arrive? Planning around the sun, moon, tides and weather shows how to predict the sun’s direction for any place and date.

Overcast light is soft, and it comes from above

A sheet of cloud turns the sun’s half-degree disc into a source that fills the whole sky. Shadows lose their edges, contrast drops, and you can photograph a subject from any side without squinting or harsh highlights. For flowers, forests, products and faces, that softness is a gift. Overcast day photography goes through subject by subject.

The storefronts above show both sides of soft, shadowless daylight. No hard shadow falls anywhere on the facade, so every brick, sign and window frame reads clearly. But nothing models the building’s depth either, and the front looks almost as flat as a drawing. The exposure tells you how much dimmer this light was than sun: 1/40 at f/8 and ISO 160 is four stops more exposure than the sunny 16 rule gives at that ISO (f/16 at 1/160), so the light on the facade was about one sixteenth as bright as direct sun.

The common misconception is that overcast light is always flattering. A heavily overcast sky is brighter overhead than near the horizon, roughly three times brighter in the standard overcast sky model used in daylighting, so most of the light falls from above. On a face that means dark eye sockets, a shadow under the nose and chin, and eyes without a catchlight. Fix it by blocking the top: stand the person under a porch roof, an awning, the edge of a tree, or just inside a doorway, facing the open sky. The light now arrives from the front and side, the eyes fill, and the bright sky appears as a catchlight. A white card or reflector held low in front of them does the same job from below.

Overcast also flattens landscapes, because the long shadows that show shape are gone. Frame out the blank sky, look for color and strong shapes that hold up without shadows, or wait for a break in the cloud.

Open shade, deep shade and dappled light

Shade is not one kind of light. What lights a shaded subject depends on what it can see.

Open shade is shade with open sky in front of it: the shadow side of a building, a covered porch facing a street, a doorway. The subject is out of the sun but lit by a large area of bright sky, so the light is soft and still has direction. It is the best portrait light you can find on a sunny afternoon. Open shade photography shows how to find it in any town.

Deep shade, under dense trees or well inside a structure, sees little sky. It is dim, very flat, and colored by whatever surrounds it: blue from the sky, green from leaves overhead.

Dappled light is sun broken by leaves into bright spots on a shadowed subject. On a face it usually looks like a mistake, a bright patch on one cheek and a dark band across the eyes. Move fully into the shade or fully into the sun, or use the pattern deliberately on a subject that suits it. Dappled light photography covers both.

One setup works almost everywhere: subject just inside the shade line, facing out toward the open sky, with a sunlit background behind them. The face gets soft light, the background glows, and the brightness difference separates the two. Expect a blue cast in shade; a shade or cloudy white balance preset, or a custom one, warms it back.

Working in hard midday sun

When the sun is high and the sky is clear, you have five options.

• Move into open shade. Usually the quickest fix for people.
• Put the sun behind the subject. Turn them so the sun becomes a backlight and the face is lit by the sky and the ground in front, then expose for the face.
• Diffuse it. A translucent diffuser panel held between the sun and the subject makes a small hard source into a large soft one, over a small area.
• Fill the shadows. A reflector bounced into the shadow side, or a fill flash set one to two stops below the daylight, lifts dark eye sockets without looking added.
• Use the hardness. Strong graphic shadows suit street, architecture and abstract work. Make the shadows part of the composition rather than an accident.

Hard sun can also exceed your sensor’s dynamic range, so watch the highlight warning and decide which end you will let go.

Photographing people outdoors most of the time? Outdoor portrait photography applies all of this to faces, posing and backgrounds.

Window light, and why distance changes it

A window is a large, directional, soft source that you can use all day, and it is the easiest way to learn lighting indoors. Two things control it: how big the window looks from the subject, and how far away the subject is.

Put the subject close to a large window and the window fills a big part of their view, so the light is soft and bright. Move them back across the room and the window shrinks in their view: the light gets harder and dimmer, and less of it wraps around to the shadow side, so contrast rises. “Further from the window is softer” is a common misconception; it is the other way round.

You may read that window light follows the inverse square law, where doubling the distance leaves a quarter of the light. That law describes a small source. Close to a large window, light falls off much more gently than that, because different parts of the window are at different distances from the subject. Only once you are several window-widths away does it start to behave like a small source, and then doubling the distance does cost close to two stops.

Which way the window faces matters too. A window facing away from the sun’s path (north-facing in the northern hemisphere, south-facing in the southern) gets little or no direct sun, so its light is soft and steady all day. A window facing the sun’s path gets beams of direct sun for part of the day: hard and patchy unless a sheer curtain diffuses it. Turn the subject at about 45 degrees to the window for a lit side and a gently shaded side, or face them to the window for even light. Moving the subject toward the edge of the window, or turning them so the light skims across the face instead of hitting it head on, is called feathering, and it gives a gentler step from lit side to shadow. Window light portraits has the full set of setups for faces.

Adding light and taking it away

Natural light does not mean no control. Three cheap tools let you shape it.

A reflector adds light. Held on the shadow side, it bounces some of the main light back in. White gives subtle, neutral fill; silver gives stronger, crisper fill; gold adds warmth that can look like late sun, or like a cast if overdone. The closer the reflector, the stronger the fill. Pale walls, sand and snow do the same.

A diffuser enlarges the source. It sits between the sun and the subject and spreads the light, which softens the shadows and drops the brightness by a stop or more.

A dark surface takes light away. In soft light the problem is often too little shape, not too much shadow. A black card, a dark wall, or a dense hedge beside the subject blocks the light that would have bounced in from that side, so the shadow side deepens and the face gains shape. This is negative fill, and it is the most useful trick for overcast days and open shade.

Want to plan a setup before you try it? The lighting diagram tool draws a top-down plan of subject, camera and lights; treat the key light as your window or sun and the fill as your reflector.

How bright natural light is, in stops

Daylight varies hugely in brightness, and knowing roughly how much helps you set an exposure and know when the light will run out. The sunny 16 rule gives a starting point: in direct sun, at a shutter speed of 1 over your ISO, use f/16. Each step dimmer costs one stop. At ISO 100 and 1/125:

Past that, light drops fast. A full moon is roughly 400,000 times fainter than the sun, close to 19 stops, which is why moonlight photography needs exposures of many seconds.

Two situations reliably fool the meter in natural light. In backlight the bright background pulls the exposure down and the subject goes dark: meter the subject with spot metering, or add one to two stops of exposure compensation. In snow or bright sand the meter tries to make the scene mid-grey and underexposes it, so add about one to two stops. Shooting RAW gives you room to correct white balance and recover a little in both directions afterwards.

Weather and the seasons

Weather changes daylight as much as the hour does. Fog and mist scatter light in every direction, so the source becomes the air itself: shadows vanish and distant layers fade, which builds depth. Fog photography covers how to expose for it. A clearing storm often throws low sun against a dark sky, the strongest contrast daylight offers. Photography in bad weather covers rain, snow and wind. When sun breaks through haze or cloud gaps, the beams become visible; god rays photography explains when to expect them.

The seasons change the sun’s path. Away from the tropics, the winter sun stays low all day, so side light and long shadows last through much of the day; in summer the sun climbs high, midday is harsh for longer, and the good light comes early and late. Near the equator the sun rises and sets steeply all year, so the low-sun period is short. Winter photography covers snow exposure and cold.

Common mistakes and misconceptions with natural light

• Thinking golden hour light is soft. On a clear evening shadows are still hard-edged. It is warm, low and lower in contrast. For soft light at sunset you need haze or thin cloud.
• Assuming overcast is always flattering. It is soft top light. Block the sky above the subject and let the light come from the front, or the eyes go dark and lose their catchlights.
• Keeping the sun behind you. It gives flat light and squinting subjects. Try side light or backlight first.
• Treating all shade as the same. Open shade facing a bright sky is soft and directional. Deep shade under trees is dim, flat and green or blue. Look at what the subject can see.
• Moving a subject further from the window to soften the light. Further away is harder and darker. Move closer, or use a bigger window.
• Half in shade, half in sun. A face split by a shade line or dappled spots almost never works. All in, or all out.
• Letting the meter decide in backlight and snow. Both fool it. Check the subject, not the overall frame, and correct.
• Ignoring reflected color. A green lawn or a red wall tints the shadow side. Move the subject or plan to correct it.

Try this: walk a circle around one subject

This takes ten minutes on any day with sun, and teaches direction, hardness and exposure at once.

1. Pick a still subject outdoors at about head height: a person willing to stand still, a statue, a fence post with a hat on it, a potted plant on a wall. Do it when your own shadow is longer than you are tall if you can.
2. Stand with the sun behind you and take one frame. Then walk around the subject in eight steps, a frame every 45 degrees, keeping the same distance and framing, until you are back where you started. At one point you will be shooting straight into the sun.
3. Now move the subject into open shade, facing out toward the open sky, and take two more frames: one from the front, one from 45 degrees to the side.
4. If you have a white card, sheet of paper or reflector, take one last backlit frame with it held low in front of the subject.

How to judge it. Lay the frames out in order. Find the one where you can see the most shape and texture; it will almost always be one of the side-lit frames. In each frame, check where the shadow side falls and whether the shadow edge is crisp (sun) or gradual (shade). On a face or a shiny surface, look for a catchlight and see which frames have one. Compare the backlit frame with and without the card: the shadow side should be visibly lighter. If the backlit frame without the card has a dark subject, that is the meter being fooled, and you now know what to correct next time.

Natural light questions

What is the best time of day for natural light photography?

It depends on what you want. Low sun gives warm, directional light with long shadows for texture. Overcast gives soft light all day for faces and close-ups, and blue hour gives soft, cool light that balances with city lights. Sun or cloud is not better or worse; they do different jobs.

How do I photograph people in harsh sun with no shade nearby?

Turn them so the sun is behind them and expose for the face, which is now lit by the sky and the ground in front. A reflector or a white card held low in front of them adds fill and a catchlight. If you have a flash, fill at one to two stops below the daylight does the same job.

Why do my photos in the shade look blue?

In shade the subject is lit by blue sky rather than the sun, and that light is much cooler. Auto white balance often leaves some of the blue. Use the shade preset, set a custom white balance off something neutral, or shoot RAW and warm it afterwards.

Do I need any equipment for natural light photography?

No, a camera or phone is enough. A collapsible reflector with a diffuser panel is the most useful extra because it lets you add fill, soften sun and take light away with the dark side. A white card and a dark jacket do a surprising amount of the same work.
