How to Blur or Replace a Photo Background (DSLR Portrait Effect)

TL;DR

Once PhotoRepair isolates your subject, you can drop in a new background — a color, a scene — or blur the original for a DSLR-style portrait look, all composed on-device.

Steps

In PhotoRepair, remove the background to isolate your subject.
Choose a new background — a color, an aesthetic scene, or a blur of the original.
For a portrait look, keep the subject sharp and blur behind them.
Adjust so the subject sits naturally against the new background.
Export the finished image.

Why it works this way

The DSLR “portrait” look comes from a sharp subject against a soft background — something phone cameras approximate but can’t always nail. By cutting out the subject first, PhotoRepair lets you blur the real background convincingly, or swap it entirely for a clean color or new scene. It’s all composited on-device, so nothing is uploaded.

Tips & edge cases

Blur for portraits, replace for product shots on a clean color.
Match the lighting when dropping in a new scene so the subject doesn’t look pasted.
Refine edges first — a rough cutout shows most against a new background.

FAQ

Can I get a DSLR-style blurred background? Yes. Keep your subject sharp and blur the original background for a shallow-depth-of-field portrait look.

Can I put my subject on a different scene? Yes. Replace the background with a new color or scene after the AI cuts out your subject.

Is this done on-device? Yes. The cutout and compositing run locally, with no uploads.
