The Portrait Lighting Effects:
The new feature in iPhone 8 Plus brings professional level lighting effects to your iPhone. Portrait Lighting feature lets you do the same without an expensive camera setup.
Step 1: Open the Photos app and find the Portrait mode shot you want to edit.
Step 2: From the photo, tap on Edit.
Step 3: Scroll to see all the effects. Tap on an effect to add it.
Step 4: If you want to go back to the default effect, just go back to Natural Lighting effect.
Right now, there are 5 different types of lighting effects.
Natural Light: This default Portrait Mode effect keeps the person’s face in focus and blurs the background.
Studio Light: This is probably the best effect and the one you’ll end up using often. This effect brings out more detail in the person’s face. It’s also more brightly lit.
Stage Light: The background will be pitch black and the subject will still be in color (although the colours will be a bit muted).
Contour Light: Now things start to get dramatic. This effect will add a shadow to the face and the surroundings.
Stage Light Mono: If you want a black and white portrait that only shows the face, and turns everything else dark, this is the effect for you.
