From Civitai:

Settings I use are either Euler/Simple or Euler_Ancestral/Beta, CFG 1, 8 steps to just generate an image, 10 steps to edit, with a reference image.

The training data was captioned using a template with this sort of layout, so making your edit prompts, follow this structure for best results.

[1 line of intent, optional]

Change [ANCHOR A]'s [attribute] from [old] to [new], keeping [structure/style/light] the same.

Change [ANCHOR B]'s [attribute] from [old] to [new], keeping [structure/style/light] the same.

Convert [ENVIRONMENT] from [old state] to [new state]: update [sub‑element 1], [sub‑element 2], [sub‑element 3] accordingly; keep [parts of that environment that must stay] unchanged.

Do not change anything else — keep [faces/expression], [pose/position], [clothing & props & their colours], [framing/angle/composition/aspect ratio], and [subject/object count] exactly as in the reference.
