How to use
先按最窄的比例构图，其他比例裁切时才不会丢主体。
Try tweaking it
- Swap style words for measurable parameters: light, lens, material, composition.
- Ask for three variants of one prompt, then compare the differences.
What you should get
- A parameter sheet you can act on (light, lens, material, framing)
- Two or three alternatives with trade-offs
Common mistakes
- Stacking words like "premium, cinematic, 8K" — no two results match.
- Asking for a real brand or celebrity look and getting something close but unusable.
How to check the output
- Parameters are executable — ready to use in a tool or hand to a designer.
- It explains the trade-offs, not just the final look.
Where it works
- Good for: breaking vague "premium feel" into concrete light, material, lens and composition parameters.
- Watch out: for real brands, celebrities or third-party work, use equivalent descriptions to avoid infringement.
