How do I expose for a backlit portrait?

Meter for the subject, not the background. Switch to spot metering and read directly off the face, or stay in evaluative metering and dial in +1.5 to +2 stops of exposure compensation. Manual mode locks the exposure so it doesn't shift when you recompose. The background may blow out, and that's usually fine. An overexposed golden-hour sky behind a well-lit face reads as ethereal, not broken.

Is lens flare always bad?

No. There are two kinds, and they behave differently. Veiling flare is the invisible kind that washes out contrast and makes images look hazy, and you want to minimize it. Ghosting and streaking are the visible circles, hexagons, and streaks. Those can ruin a shot or add atmosphere depending on how you compose. A clean lens, a lens hood, and small position changes are how you control which kind you get.

Can autofocus work when shooting into the sun?

Yes, on modern cameras. Contrast-detect and phase-detect systems handle backlight reasonably well, and face-detect or eye-detect AF locks onto a subject regardless of background brightness. If the camera still hunts, pre-focus with the sun partially blocked and recompose, use back-button focus to lock and shoot, or switch to manual focus with focus peaking if you're on a mirrorless body.

What's the best time of day for backlight?

Golden hour at sunrise or sunset. The sun sits low, the tones run warm, and the dynamic range stays manageable. A low sun is easy to partially obscure behind a subject's head, which tames flare while keeping the rim light. Overcast with a bright patch of cloud behind the subject also produces soft backlight without extreme contrast. Midday sun sits too high for traditional backlit setups.

How do I make a silhouette work?

Meter for the sky so the subject falls into shadow. Use evaluative metering or spot meter on the brightest part of the background, and dial in -1 stop if the silhouette isn't dark enough. The outline has to carry the photo, so pick subjects with recognizable shapes: a person with arms raised, a tree with distinctive branches, a skyline. Pair it with a dramatic backdrop like a blazing sunset.

Mastering Backlight: Myths, Metering, and Magic

“Never shoot into the sun.” It’s one of the first rules new photographers learn, and it’s one of the first they should forget. Some of the most compelling photographs ever made are backlit: subjects glowing with rim light, sunflare streaking across the frame, silhouettes cut sharp against blazing skies.

The advice to avoid backlight exists because it’s technically challenging. Your camera’s meter gets confused, autofocus hunts, and lens flare can ruin an image if uncontrolled. But these are solvable problems, not reasons to avoid an entire direction of light.

Let’s dismantle the myths, solve the technical problems, and turn backlight into one of your most reliable tools.

Myth 1: Backlight Always Creates Silhouettes

The claim: If the light source is behind your subject, the subject will be dark.

The reality: A silhouette happens when you expose for the bright background and let the subject go dark. It’s a creative choice, not an inevitability. If you expose for the subject instead of the background, you get a properly lit subject with a bright (potentially blown) background and a rim of light around the edges.

These are two completely different photographs from the same lighting situation. The difference is where you point your meter.

How to get a properly exposed backlit subject:

Spot metering: Switch your camera’s metering mode to spot. Meter directly on your subject’s face or the area you want correctly exposed. The camera will ignore the bright background and expose for what matters.
Exposure compensation: In evaluative/matrix metering, dial in +1 to +2 stops of exposure compensation. The camera wants to darken everything to compensate for the bright backlight. Push it back up.
Manual mode: Meter for the subject, set your exposure, and lock it in. This is the most reliable method because your exposure won’t shift as you recompose.

Yes, the background may blow out. That’s usually fine. A slightly overexposed golden-hour sky behind a properly exposed portrait looks ethereal, not broken.

Myth 2: Lens Flare Ruins Photos

The claim: Flare washes out your image and destroys contrast.

The reality: There are two types of lens flare, and they do very different things.

Veiling flare is the invisible kind. Light bouncing around inside your lens reduces overall contrast without creating visible artifacts. Your image looks hazy and washed out. This is the kind you usually want to minimize.

Ghosting and streaking are the visible artifacts: circles, hexagons, and light streaks across your frame. These can absolutely ruin a photo. They can also add atmosphere, warmth, and a sense of being present in a moment. A golden sun flare streaking through a portrait at golden hour is a feature, not a bug.

How to control flare:

Use a lens hood. Always. It blocks stray light from hitting the front element at extreme angles.
Adjust your position. Moving 6 inches left or right changes the angle of light entering your lens and can eliminate or introduce flare. Small movements, big differences.
Partially block the sun. Position the sun behind a tree branch, a building edge, or your subject’s head. This creates a sunstar or reduces flare intensity while keeping the backlit quality.
Clean your lens. Fingerprints and dust on the front element scatter light and amplify veiling flare. A clean lens handles backlight far better than a dirty one.
Embrace or eliminate, don’t leave it to chance. The worst flare is the kind that looks accidental. If you want flare, compose to make it look intentional. If you don’t, shade your lens or reposition.

Myth 3: You Need Expensive Multi-Coated Lenses

The claim: Only high-end lenses with advanced coatings can handle backlight.

The reality: Modern lens coatings have improved dramatically even in budget glass. A current 50mm f/1.8 handles backlight far better than an expensive zoom from 15 years ago. Technique matters more than coatings.

That said, some lenses do handle backlight better than others. Prime lenses generally flare less than zooms because they have fewer glass elements for light to bounce between. But the difference is manageable with proper technique, not a reason to upgrade.

Myth 4: Autofocus Can’t Work in Backlight

The claim: Your camera will hunt for focus when shooting into bright light.

The reality: This was more true a decade ago. Modern contrast-detect and phase-detect autofocus systems handle backlight reasonably well, especially face-detect and eye-detect AF, which lock onto your subject regardless of background brightness.

If your AF does hunt:

Pre-focus and recompose. Focus on your subject with the sun partially blocked (by turning slightly), lock focus, then recompose.
Use back-button focus. Decouple focus from the shutter button. Lock focus, then shoot as many frames as you want without the camera refocusing.
Switch to manual focus. For static subjects, backlit scenes are a great time to focus manually. Use focus peaking on mirrorless cameras for precision.

How to Meter for Backlight: A Practical Workflow

Here is the step-by-step process I use for every backlit situation:

Step 1: Evaluate the Scene

Ask yourself what you want: a silhouette, a properly exposed subject with a bright background, or a balanced exposure where both subject and background retain detail.

Step 2: Choose Your Metering Approach

For silhouettes: Use evaluative metering as-is, or spot meter on the sky. The bright background drives the exposure, and the subject goes dark. Dial in -1 stop if the silhouette isn’t dark enough.

For exposed subjects: Spot meter on the subject. Or use evaluative metering with +1.5 to +2 stops exposure compensation. Chimping (checking the LCD) is perfectly acceptable here because backlit metering is genuinely tricky and varies shot to shot.

For balanced exposure: This requires either fill flash, a reflector, or HDR/exposure blending. The dynamic range between a bright backlit sky and a subject in shadow can exceed 6-8 stops, which is beyond what a single exposure can hold.

Step 3: Position the Sun

Where the sun sits relative to your frame changes everything:

Sun fully in frame: Maximum flare, most dramatic. Hard to manage but stunning when it works. Partially obscure the sun behind the subject’s head to control intensity.
Sun just outside frame: Rim light on the subject’s edges without direct flare. Often the most practical position for portraits.
Sun well behind and above the subject: Broad, soft backlight. Less dramatic but easier to expose for. Good for even rim light.

Step 4: Shoot and Adjust

Take a test shot. Check the histogram. Your subject should be in the right half of the histogram (well-exposed to slightly bright). The background will likely clip on the right edge, and that’s acceptable. Adjust exposure compensation and reshoot until the subject looks right.

When Silhouettes Are the Right Choice

Silhouettes aren’t failed backlit photos. They’re one of the most powerful techniques in photography when used intentionally.

A silhouette works when:

The outline is recognizable. A person with arms raised, a tree with distinctive branches, a skyline. The shape must tell the story because there’s no detail visible.
The background is dramatic. A blazing sunset, a textured sky, backlighting through stained glass. The silhouette needs a compelling backdrop.
The mood calls for mystery or drama. Silhouettes hide identity, obscure detail, and create a sense of anonymity or atmosphere.

Technical settings for silhouettes: Meter for the sky. Use evaluative metering or spot meter on the brightest part of the background. Set a small aperture (f/8 to f/11) for a defined sunstar if the sun is in frame. Shutter speed will typically be fast (1/500s or faster) because you’re exposing for bright light.

Backlight by Time of Day

Sunrise/sunset (golden hour): The classic. Low sun, warm tones, manageable dynamic range. Best for portraits, silhouettes, and any scene where you want warmth and rim light. The lower the sun, the easier it is to partially obscure behind subjects.

Midday: The sun is too high for traditional backlight. But if your subject is on a hill, stairs, or elevated position, you can create a backlit situation from below. Less practical, more specialized.

Overcast with bright patch: A bright area of cloud behind your subject creates soft backlight without the extreme dynamic range of direct sun. This produces a gentle rim light effect that’s flattering and easy to expose for.

Indoor window backlight: A window behind your subject. Same principles as outdoor backlight, but the dynamic range is more extreme because the interior is much darker than the exterior. Expose for the subject and let the window blow out, or use sheer curtains to reduce the background brightness.

Common Mistakes

Exposing for the background and wondering why the subject is dark. This is the most common backlight error. If you want the subject visible, meter for the subject.

Shooting with a dirty lens. Fingerprints and dust amplify veiling flare and reduce contrast. Clean your front element before every backlit session.

Standing too far from the subject. In backlit portrait situations, being closer (and using a longer focal length from that closer distance) helps minimize the proportion of bright background in the frame and reduces flare.

Ignoring the rim light. Rim light is the signature of backlit photography. If you’re shooting backlit but your subject has no visible edge light, the sun isn’t positioned correctly. Move until you see that glowing outline.

Over-processing in post. A common temptation is to recover blown highlights in the sky behind a backlit subject. Sometimes this works. Often it creates an unnatural halo effect. If the sky blew out, consider letting it stay bright. That’s the look of backlight.

A Challenge

Next golden hour, go outside with a willing subject (or a bicycle, a plant, a fire hydrant, anything with a recognizable shape). Position the sun directly behind them. Take three versions:

Silhouette: Expose for the sky.
Exposed subject: Spot meter on the subject or add +2 stops compensation.
Flare shot: Put the sun partially in frame, let the streaks fall where they will.

Compare the three. You’ve now produced three entirely different images from the same light, the same subject, and the same position. That’s what understanding backlight gives you: options.
