Bloom and Halation recreate the way light used to behave in old lenses and on film — the soft glow around a streetlight, the warm halo bleeding around a backlit subject's hair. They're the difference between a photo that looks *captured* and one that looks *remembered*: dreamy, atmospheric, a little nostalgic.

Both effects come from how light diffuses through glass and film, and they complement each other. **Bloom** softens and spreads the brightest areas outward into a gentle glow. **Halation** is more subtle — a warm orange halo that forms only on the hard edges of high-contrast highlights, exactly like vintage film. You'll find both inside [Adjustment Sliders](/help/edit/adjustment-sliders) under **Texture**, so build your base tonal edit first, then add them as a finishing touch.

## Bloom: a soft, glowing light

Bloom makes the brightest parts of a photo bloom outward, wrapping light sources and bright edges in a gentle, radiant glow. Photographers used to chase this look physically — smearing a little vaseline on a filter, or stretching a stocking over the lens — to soften highlights while keeping the focal point sharp. Bloom gives you that ethereal quality with a single slider.

It's at its best wherever light is part of the story: golden-hour and backlit **portraits**, where it adds a flattering glow to skin; **night scenes**, where it softens harsh streetlights and neon into something cinematic; **weddings and events**, for romantic, emotional moments; and **sunrise/sunset landscapes**, where it tames the sun and smooths the transition between bright sky and darker land. Try pairing it with the Exposure and Highlights sliders to shape the glow, or a touch of [Color Grading](/help/edit/color-grading) to warm a golden-hour scene.

## Halation: warmth at the edges

Halation adds a subtle red-orange glow around high-contrast edges, the kind you'd get when light scattered through a film's layers and reflected back. On film it was an imperfection manufacturers tried to suppress; photographers loved it anyway, because it lends an unmistakable vintage warmth and character.

Because it works on contrast, Halation depends on the light in your scene. **Backlit portraits**, **high-contrast scenes**, and **urban night photography** light it up beautifully; an evenly lit, low-contrast frame may show almost nothing. That's expected — reach for Halation when there's drama in the light, and lean on more Contrast or the Shadows slider beforehand to give it edges to work with.

## Using them together

Bloom for atmosphere, Halation for edge warmth — used together and kept restrained, they build a cohesive, filmic look. Add a little grain or fade and you've got a convincing analog rendering. The usual caution applies: these effects stack quickly, so start low. If glow turns to haze and your image goes flat, pull Bloom back before touching contrast.
