Why one at a time beats all at once
A tourist photo with six strangers in it is not one big erase. If all six are filled in a single pass, each hole is rebuilt from surroundings that still contain the other five holes, and the result smears. Erasing them one after another lets each repair use the real background revealed by the previous ones. The order matters too: the smallest figures — usually the farthest away — go first, because they are the easiest to rebuild and they clean up the backdrop that the larger, nearer figures need.
How Sweep works
When the photo opens, the People finder runs on your device and outlines the people who stand out from the background. Sweep turns that outline into a list: one row per person, with a small thumbnail cut from the photo in this tab's memory and never stored. You tick Keep on your subject. Everyone left unticked is queued. Erase all then works through the queue, smallest first, each person as its own edit — so if one comes out badly you can undo just that one, or use Restore on its step in History, without losing the others.
Where a stranger is touching someone you kept, the editor leaves a 6-pixel margin next to your subject rather than risk shaving their shoulder off, and tells you when it did. A few strokes of the brush followed by Erase take care of what remains.
What the finder can and cannot see
The finder separates people from the background; it does not recognise or identify anyone. Two people standing close together come out as one row — split them with the brush, or tick Keep and erase the other one by hand. Small, distant or partly hidden figures are often missed; click them and Smart Select picks them out, or brush them. Shadows on the ground belong to the person who cast them: Remove person from photo covers single removals with the shadow included, and Photo cleanup handles the litter and signs that are usually left behind.
Getting a clean result
Large figures in the foreground leave large holes, and the larger the hole the more the AI has to invent. If a near figure covers architecture, turn on Structure Repair so straight edges continue through the gap. If a rebuilt area looks wrong, “Try another result” offers a different reconstruction, and “Pick region source” lets you drag a box over clean background for the repair to copy from.
