Halation. Let the light linger.

Give bright lights a warm red-orange halo. Turn headlights, window light and sunlit edges into part of the feeling of your photograph.

A little warmth at the edge of light.

Halation is the coloured glow associated with light scattering back through film. Photonica recreates that character around bright areas, letting a warm fringe reach into the surrounding shadows.

Move the divider: before on the left, Halation 100 / radius 3 on the right. Look along the lower edge of the headlight.

Start with a bright edge.

A headlight against a dark street gives the glow somewhere to show. Window reflections, illuminated signs and backlit hair are good places to experiment, too.

A softly lit scene with little contrast may show only a gentle change. Halation follows the light that is already in your photograph.

These examples were made in Photonica. “Before” retains the photographer’s original treatment. Halation is a creative interpretation of a film effect.

More glow. More room to spread.

Amount controls how pronounced the halo is. Radius changes how far it spreads. Adjust one at a time and watch the same bright edge.

Follow the daylight, too.

Look for sunlight catching a glass rim or a bright window behind a darker subject. The small highlights can pick up warmth while the rest of the scene keeps its detail.

Halation or diffusion?

Use halation for a coloured fringe around bright light. Use diffusion for a broader veil of scattered light and softer contrast. You can combine them, then lower either amount if the image feels too hazy.

How to add halation to a photo.

Start with your own photograph. Halation is free and works with or without a film look.

  1. Open your photograph.

    Open the editor and choose a photo with bright highlights. Your image is processed locally on your device.

  2. Find Light, then Halation.

    Raise the halation amount from zero. Try 35 as a starting point, then compare the bright edges with your original.

  3. Shape the halo.

    Adjust Halation radius for a tighter fringe or a wider glow. Check both the whole photograph and a close detail before saving your JPEG.

A few things to know.

Why can I barely see the effect?

Look for a bright highlight next to a darker area. Increase the amount, then try a wider radius. An evenly lit surface gives the halo less contrast, so changing the photograph may help more than pushing every setting.

Do I need to choose a film first?

No. Halation works on its own. The night and window-light examples on this page have only halation added. You can also combine it with a film look and grain.

Can halation recover a blown-out highlight?

No. It adds a glow around bright areas; it cannot restore detail missing from the original photograph.

Is halation free?

Yes. Amount and radius are both free, with no account needed to edit or export. Pro adds original-resolution export and other creative tools.
