Add halation glow to your photos, free
On film, bright light passes through the emulsion, bounces off the back of the film base and comes back up through the bottom layer — the red-sensitive one. So every light gets a red-orange rim, whatever colour it was: tight, densest right at the edge, and gone within about 1% of the frame. CineStill 800T has no anti-halation backing, which is why its night photos glow like that.

This tool does the same: only near-white lights bleed, the rim hugs them in red, the light itself stays white, and the rest of the photo is left alone.
How to use it
- Open the halation tool and load a photo.
- It works out of the box on night photos with lamps, signs or neon. Threshold sets how bright a light must be to bleed.
- Glow is how strong the rim is; Spread is how far it reaches — keep it low for the tight film look.
- Adjust Hue — warm red is the classic film look.
- Export.
Tips
- Night scenes with practical lights are the ideal source.
- Keep threshold high so midtones do not wash out.
- Pairs naturally with film emulation.

What is halation in photography?
Halation is the glow around bright highlights caused by light reflecting inside film and scattering back through the emulsion, often with a reddish tint.
How is it different from bloom?
Bloom is a soft haze over everything bright. Halation is a tight red rim around lights, from light reflecting off the film base — the light stays white and the rest of the frame is untouched.
