Quick answer

## The short version

Compare whether the task needs a small repair based on nearby pixels or a larger invented area. Tool names vary, so confirm what the selected command actually does in your editor.

## A capture or editing plan

Start with a duplicate and select the smallest area that addresses the problem. Test a conventional fill when nearby texture provides enough material. Consider generative expansion when the required region extends beyond the captured scene and invention is acceptable. Compare both results without changing the original. Check product details, people and text independently from whether the fill looks smooth.

## When to change the approach

Neither method provides evidence of missing original content. A larger or more complex selection increases the amount that must be reviewed.

## Worked planning example

Planning example: A small empty strip beside a plain wall may be filled using nearby texture. A wide extension around a crowded street needs invented scene decisions, so it should not be treated as a factual continuation of the location.

## If the first attempt fails

If a fill removes the intended object but produces a conspicuous repeat, inspect the sample surroundings rather than applying it again over a larger area. Expansion and local removal have different boundaries and review needs. Try the smallest reversible edit first, then compare texture and geometry at the final size. Keep the layer or source copy that makes the scope of the change understandable later.

## Before you finish

1. Define the exact region to change.
2. Test a smaller conventional edit first.
3. Label generated surroundings honestly.
