About Focos

Focos is a computational photography app that lets you refocus photos and simulate different lens apertures after capture. It uses the iPhone's dual-camera depth data to create realistic bokeh effects.

What it does

After taking a photo with Portrait mode, Focos extracts the depth map and lets you change the focal point, blur strength, and lens shape. You can also apply light leaks, film grain, and other analog-style effects.

Best for

iPhone photographers who want more control over depth of field
Social media creators looking for cinematic portrait effects
Hobbyists experimenting with computational photography

Strengths

Post-capture focus adjustment works with any Portrait mode photo
Simulates real lens apertures (f/1.4, f/2.8, etc.) with accurate bokeh
No learning curve—basic edits are one-tap

Key features

Depth editing — change focus point and blur intensity after shooting
Lens simulation — choose from 20+ aperture shapes and sizes
Light leaks & flares — add analog-style effects to photos
Film grain — apply realistic grain textures
Export options — save as HEIC, JPEG, or TIFF with depth data
