HOW TO Master bokeh on your iPhone

1 Set f–stop

Tap to select Portrait mode. Tap the f–stop icon to dial in an aperture value. The lower the number, the blurrier the bokeh will be. Here we’ve gone for f8.0. By default we’re using the Natural Light preset. Take the shot.

2 Adjust blur

In Photos tap Edit. Tap the f–stop icon. Drag the aperture slider to a larger number (such as f16) to reveal more background detail. Drag it to a smaller number for more blur. The 12 Pro Max can open to a wide f1.4.

3 Adjust lighting

Tap the hexagonal icon to access the Lighting Effects wheel. Drag to experiment with different studio effects such as the face–modelling Contour Light. Here we’ve gone for Studio Light to brighten the face.
