Another example showing a different scenario for this editing task.

Prompt:

create header images for substack newsletter posts and publications with attention to detail, matching lighting and perspective

Try This →

If something looks off

AI changed the wrong area

Why: The AI couldn't determine exactly which area you meant from the description alone.

Try: Tap a marker on the specific area you want to edit, then regenerate with the same prompt

Try This →

Tip: Markers tell the AI exactly where to focus. Use them when description alone is ambiguous.

Result looks unnatural

Why: The AI may need more specific guidance about the look you want.

Try: Add 'natural lighting and sharp details that match the rest of the photo' to your prompt

Try This →

Tip: Adding 'natural' and 'realistic' to your prompt helps the AI prioritize believability.

Lighting doesn't match

Why: The edited area has different lighting than the original scene.

Try: Add: 'match the lighting direction and color temperature of the original photo'

Try This →

Tip: If light comes from one side in the original, mention it: 'with light from the left side.'

Edges look rough or artificial

Why: Transitions between edited and unedited areas need refinement.

Try: Tap markers on the rough edges and regenerate: 'refine these edges for a seamless blend'

Try This →

Tip: Edge refinement is the most common adjustment — markers on problem areas make it quick.
