Copyable starting prompts

Prompt 1

Replace only the background with [new scene]. Keep the subject's face, pose, clothing, scale, and crop unchanged. Match controlled studio key and fill; preserve clean hair and object edges.

Use example 1 as a starting structure.

Replace the subject, action, setting, and constraints with the real request.

Prompt 2

Mask the current background and place the unchanged subject in [location]. Match perspective and shadow direction, keep all lettering readable, and do not add extra people or objects.

Use example 2 as a starting structure.

Replace the subject, action, setting, and constraints with the real request.

Prompt 3

Change the background to [description] using layered foreground, midground, and background. Preserve the foreground pixel boundaries, identity, and proportions; blend contact shadows without altering the subject.

Use example 3 as a starting structure.

Replace the subject, action, setting, and constraints with the real request.

How to revise a failed prompt

  1. If the subject changes, strengthen identity/reference constraints.
  2. If motion or composition is wrong, describe one observable action and one camera instruction.
  3. If artifacts appear, simplify the scene and reduce simultaneous changes.
