Shadow and Contact Point — Chinese original prompt
这张合成图里[产品]看起来像浮在空中。请给出影子修正方案：1）判断光源高度与影子应落的位置；2）接触阴影与投射阴影的区别和画法；3）影子的柔和度、透明度与颜色（不是纯黑）；4）木、石、布三种台面对影子的影响；5）需要增加的环境反射。用可调参数的形式输出，便于逐项修改。

How to use
贴地一层深、远处一层淡，两段影子才有重量感。
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.
