Many beginners are told to keep the sun behind them. But some of the most beautiful photographs are made by doing the opposite: shooting toward the light. Backlight makes hair glow, leaves shine like stained glass, dust and mist sparkle, and shapes stand out against bright skies. It also brings challenges: flare, exposure and dark faces. This lesson focuses on the light itself, what backlight does and how to place it. The exposure side was covered earlier in the exposure course.
What is backlighting?
Backlighting means the main light comes from behind the subject, shining toward the camera. You met it briefly in front, side, back, top and low-angle light. The camera mostly sees the side of the subject turned away from the light, while the light catches its edges and passes through anything thin or translucent.
How to expose backlit subjects, including when to expose for the face or for the sky, was explained in backlighting, silhouettes, high-key and low-key exposure. Here we look at what backlight does and how to position it.
Five effects of backlight
| Effect | What you see | Best conditions |
|---|---|---|
| Rim light | A thin bright outline around hair, shoulders or an object's edge | Low sun behind, dark background |
| Translucency | Thin materials glow from within: leaves, petals, fabric, ears | Strong light shining through |
| Glow and haze | Soft, bright, dreamy atmosphere | Low sun, dust, mist or humid air |
| Silhouette | Dark shapes against bright light | Bright background, subject not lit from the front |
| Flare and sunstars | Streaks, circles, haze or star points from the sun | Sun in or near the frame |
Rim light
Rim light is the bright edge created when light from behind catches the outline of a subject. It separates the subject from the background and adds depth and a sense of quality. It shows most clearly against a darker background. A rim of light around hair against bright sky barely shows; the same rim against dark trees glows strongly.
- Place the sun behind and slightly to one side of the subject, not exactly behind.
- Choose a darker background so the rim stands out.
- Look for the glow on hair and shoulders and adjust your position until it appears.
In the studio, photographers recreate this with a dedicated light behind the subject, covered in background lighting and subject separation.
Translucency and atmosphere
Light passing through thin materials makes them glow with rich color: autumn leaves, flower petals, grass, a cotton dress, even the edges of ears. Front light would show only their surface; backlight shows their inner color and structure. Backlight also lights up anything in the air: dust, smoke, mist, rain or spray become visible as glowing texture.
Silhouettes
When the subject has little or no light on its front and the background is bright, it turns into a dark shape. As a lighting choice, a silhouette needs a clean, bright background, such as sky or a lit window, and a subject with a clear outline. The exposure method was covered in silhouette exposure.
Flare: problem or tool
When strong light hits the front of the lens, it bounces inside and causes flare, as explained in optical limitations. Flare lowers contrast and adds streaks or circles.
| To reduce flare | To use flare creatively |
|---|---|
| Use the lens hood | Let the sun just touch the edge of the frame |
| Shade the lens with your hand or a hat | Hide the sun partly behind your subject or a tree |
| Hide the sun behind an object | Use a small aperture to turn the sun into a star |
| Keep the front of the lens clean | Shoot in low golden-hour sun for warm haze |
Warning:Never look at the sun through an optical viewfinder or with a long lens, especially when it is high and bright. It can permanently damage your eyes. Use live view or keep the sun out of the frame when composing.
Lighting the front of a backlit subject
With backlight, the side facing the camera is in shadow. For portraits you often want the face lit as well as the glowing rim. Options include:
- A reflector in front of the subject, bouncing the backlight onto the face; see reflectors and diffusers.
- Natural fill from a pale wall, sand or pavement in front of the subject.
- Fill flash, covered in fill flash in daylight.
Common mistakes
- Sun exactly behind the head with no plan: strong flare and a dark face.
- Rim light against a bright background: the glow disappears.
- Washed-out photos: uncontrolled flare reduces contrast; use the hood or shade the lens.
- Backlight at midday: the high sun is rarely behind a subject; backlight works best when the sun is low.
How professionals use backlight
Portrait and wedding photographers often plan golden-hour sessions with the sun behind their subjects, add a reflector for the face, and look for dark backgrounds to show the rim. Nature photographers seek backlit leaves, grass and spider webs early and late in the day. Filmmakers use backlight constantly to separate actors from backgrounds. They control flare deliberately, using it for warmth and atmosphere or removing it for clarity.
Practical examples
A child in a meadow
- Situation
- At sunset, you want the child's hair to glow.
- What to do
- You place the low sun behind and slightly to the side of the child, against darker trees, and hold a reflector in front.
- Why it works
- Backlight creates a rim on the hair; the dark background makes it visible; the reflector lights the face.
- Result
- A glowing outline around the hair and a softly lit, clear face.
Autumn leaves
- Situation
- Leaves look dull when photographed with the sun behind you.
- What to do
- You walk around and photograph them with the sun shining through them.
- Why it works
- Backlight passes through thin leaves, revealing their inner color and veins.
- Result
- Bright, glowing orange and red leaves with visible structure.
Key points
- Backlight comes from behind the subject toward the camera.
- It creates rim light, translucency, glow, silhouettes and flare.
- Rim light shows best with the sun low and slightly to the side, against a dark background.
- Control flare with a hood, shading or hiding the sun; or use it creatively.
- Add fill with a reflector, natural surfaces or flash to light the front of the subject.

Conclusion
Backlight turns ordinary scenes into glowing, atmospheric photos through rim light, translucency, haze and silhouettes. Position the low sun behind and slightly to the side, choose darker backgrounds, control flare, and add fill to the front when needed. Next, you will learn how reflectors and diffusers let you shape natural light.
