How do you expose a strongly backlit portrait while keeping subject detail and a bright halo?

I’m trying to photograph subjects in strong backlight, similar to images with a glowing rim/halo from low sun behind the subject. My problem is balancing several things at once: keeping some detail in the subject, avoiding a completely blown background, and preserving the bright halo effect.

When I expose for the subject, the background often blows out badly. When I protect the highlights, the subject becomes too dark or turns into a silhouette. I’m shooting RAW.

Is this mainly about camera dynamic range, or are there practical shooting techniques—such as metering approach, time of day, fill light, or post-processing—that help achieve this look?

The trick here has nothing to do with metering, and everything to do with timing and atmospheric conditions.

You want to shoot late in the day when the sun is very low in the sky, preferably when there is lots of haze. This gives you a good diffuse light from the hazy area to lift the shadows and a manageable amount of rim lighting from the sun itself.

If you try this mid morning or mid afternoon or with very clear skies the contrast between the highlight and shadows will be too great, no mater how you meter or expose the photo. Even if you have a very wide dynamic range camera, or shoot multiple exposures to blend you will still have problems with flare.

Much better to simply wait until the highlight and shadows balance themselves!

This look is usually less about a special metering mode and more about controlling scene contrast.

The most important factors are timing and conditions: shoot when the sun is low, especially in hazy golden-hour light. Haze diffuses the backlight and lifts the shadows, so the contrast is much easier to manage. In clearer, harsher light, the dynamic range can simply be too great.

A common approach is to expose a bit lower to protect the bright rim light and background highlights, then lift the shadows later from the RAW file. Post-processing may also include reducing exposure in the sky/background with a graduated adjustment.

If the subject is still too dark, subtle fill flash can help balance the backlight. Done well, it won’t look obviously flashed, but it can restore detail to the face or foreground while keeping the halo effect.

So the recipe is: low hazy sun, slight underexposure to save highlights, RAW recovery in post, and optional gentle fill flash. Camera dynamic range helps, but the lighting conditions and technique matter more.
