How to Get Great Results
- Step 1
Pick a clean source
Start from a source image with a clear subject, minimal clutter, and good lighting so the model can preserve identity.
- Step 2
Describe the new setting
Write a short prompt focused on the target background, lighting, and mood (e.g., 'on dark linen with soft studio sweep lighting').
- Step 3
Match camera & scale
Keep camera angle and relative size similar to the source for stronger consistency across runs.
- Step 4
Iterate subtly
Change one variable at a time (lighting, palette, backdrop texture) to converge quickly without drifting identity.
Example Prompts
Place the same dagger on a dark linen backdrop, soft studio sweep light, crisp edges, realistic reflections
Restyle this leather satchel on aged wooden table, warm window light, shallow depth of field, natural color grade
Show the same potion bottle on marble counter, cool overhead light, soft shadows, clean minimal background
Move this miniature figurine onto a mossy forest floor, morning mist, soft volumetric light, gentle vignette
Put the same helmet on a stone plinth, gallery lighting, neutral backdrop, subtle rim light for separation
