BraveCLHow to blur a photo background on Mac
Keep a person sharp while softening a busy photo background on Mac with on-device subject assistance, a default Gaussian effect and a split comparison.
- What you'll achieve
- You will have one photo with the subject still sharp, a softer background and a split before-and-after view to inspect the result.
- What you need
- A photo with a subject you want to keep clear and a background you want to soften.
- Blur Photo Focus Studio for Mac.
A busy background can distract from the person in a photo. Blur Photo Focus Studio can suggest where the subject ends and the background begins, then blur the surroundings while leaving the subject clear. Check the suggestion before accepting it, especially around hair, hands and clothing.
1.Open a photo
Open one photo in Blur Photo Focus Studio. The full picture appears on the canvas before any blur is applied.

Make sure Assist is selected at the top right. Under Local Assistance, find Subject / Background. The app may already be in Assist when you open your photo.

Select Subject / Background to generate a suggested selection around the person. Inspect the review preview carefully, especially the outline of hair, hands and clothing.

Choose Affect Background in the review panel. The preview softens the terrace and distant water while keeping the person in focus.
Affect Background selected in Review Subject / Background; the woman is sharp and the scene behind her soft. 5.Accept the suggested region
If the suggested boundary looks right, choose Accept Suggestion. An editable Subject/background region appears with a Gaussian effect at 10 pixels.
A Subject/background region created in Regions, with Gaussian treatment and Intensity at 10 pixels. 6.Compare the original and edited photo
Use Compare to turn on the split view. Move Compare divider position to 15% so a narrow strip of the original appears beside the softened result, then review the boundary before exporting.

Tips
Inspect the suggested subject boundary before accepting it; hair, clothing and small details may need manual refinement.
The accepted suggestion uses Gaussian Intensity at 10 pixels in this example. Check the result at normal viewing size before deciding whether to refine it further.
Use the split comparison to judge the edit before you export.
Watch outSubject/background suggestions may miss or include parts of the photo. Review the whole preview before accepting a region.
