Which blend mode should I use?

Most double exposures use Screen on the top photo. A portrait on a plain, bright background underneath and a landscape on top works well.

Can I blend more than two photos?

Yes. Every photo is its own layer with its own blend mode and opacity, and you can reorder layers in Layers.

Blend two photos into one dreamy image.

1
Add two photos
Tap Photo and pick both pictures, often a portrait and a landscape or texture. The second one goes on top.
2
Choose a blend mode
With the top photo selected, open Edit and pick a blend mode. Screen gives the classic bright double exposure; Multiply darkens; Overlay adds contrast; Lighten and Darken keep only the brighter or darker parts.
3
Fine-tune
Lower the opacity to soften the effect, and drag or resize either photo until they line up.
4
Save
Tap Export. The blend is saved exactly as you see it.
