SKU 变体图制作系统

先分清:变体 SKU 图 ≠ 情绪主图

两套图逻辑不同,严格分开。本系统只解决变体 SKU 图——客户下单选款式/颜色时看的那张。

①三条核心思路

②已定的关键决策

这几个一旦定了就别再纠结,全系照做 = 统一。

③母版 + 复制:两段式工作流

保证全系一致的核心。不要每张独立描述场景——模型每次都会漂移。

1. 定母版(只做一次)
   挑最清晰的一张白底图,用【模板①】反复调到完美。这张 = 风格母版,后面全靠它。
2. 批量复制(其余每张)
   每张喂两张图:图A=定稿母版、图B=本变体白底图,用【模板②】"照搬 A 的场景、只换 B 的盒子"。背景/光/影/角度/构图全一致,只有产品不同。
3. 统一叠加文字标签
   AI 出干净图后,用固定模板(Canva/PS/Figma)叠 SKU 文字,全系字体位置一致。

④提示词模板(最终版)

Using the provided product photo, keep the wooden box EXACTLY as it is — same shape,
material, structure, color, lid type, liner and contents. Do NOT redesign or restyle it.

MATERIAL REFINEMENT (enhance, do NOT invent):
- Keep the EXACT same black-walnut grain already in the photo — do not redraw, replace
  or fabricate new grain. Only enhance its existing realism and clarity.
- Render the wood as a soft MATTE / satin finish — smooth to the eye, no glossy
  highlights, no specular hotspots, no plastic sheen.
- Bring out fine natural grain detail and the depth of the dark walnut tone with gentle
  micro-contrast — crisp but natural, NOT over-sharpened, NOT HDR, NOT crunchy.
- Smooth, even surface with soft tonal transitions so the wood "breathes".
- Overall: high clarity, rich true-to-life detail, clean sharp focus on the box.

BACKGROUND (replace the plain white):
- Surface: a warm greige / oatmeal limestone tabletop (approx #D8D1C4), very fine
  natural speckled texture, calm and uncluttered, no props.
- Light: soft, gently directional morning sunlight from the upper-left ~40°, soft-EDGED
  — not hard, not flat. One single, heavily blurred soft sunlight pool in the upper-left
  background. NO hard window-pane gobo, NO multiple light streaks.
- Atmosphere: a gentle light gradient — softly brighter near the light (upper-left),
  gently falling off toward the lower-right — giving breathing room without busy shadows.
- Shadow: one soft-edged directional shadow grounding the box, warm, consistent angle.
- Camera: low 3/4 angle (~25–30°), 85mm look, the box fully sharp; product placed
  slightly below center with generous negative space above for a text label.
- Color & mood: warm neutral — greige, oatmeal, walnut; quiet luxury, sun-kissed, calm,
  editorial. NO gold, NO cool tones, NO high contrast, NO glossy plastic.

Keep the wood grain and liner color clearly readable — light never hides detail.
Photorealistic product photography, natural and understated. Square 1:1.

基于提供的产品图,完整保留木盒本身——形状、材质、结构、颜色、盖型、内衬、内容物
都不许改,绝不重新设计或改风格。

材质优化(增强,不要凭空生成):
- 完整保留照片里黑胡桃木原本的纹理走向,不要重画、替换或编造新木纹,只增强它本来的
  真实度和清晰度
- 木头呈柔和哑光/缎面质感——视觉光滑,无高光亮斑、无镜面热点、无塑料反光
- 提升细腻自然的木纹细节和深胡桃色的层次,带轻微微反差——清晰但自然,不要过度锐化、
  不要HDR、不要发干发噪
- 表面平滑均匀,色调过渡柔和,让木头"会呼吸"
- 整体:高清晰、写实细节充分,焦点干净锐利地落在盒子上

背景(替换纯白):
- 台面:暖灰米色/燕麦石灰石(约#D8D1C4),极细天然颗粒纹理,干净无道具
- 光线:左上约40°柔和方向性晨光,柔边——不硬不平。背景左上只有一片重度虚化的柔和
  阳光光斑。不要硬窗格、不要多条光带。
- 氛围:一道柔和光线渐变——左上略亮,向右下自然变暗,给画面呼吸感,不要杂乱的影子
- 阴影:一道柔边方向投影让盒子落地,暖色,角度全系一致
- 机位:低3/4角(约25–30°),85mm观感,产品全清晰;产品略低于中心,上方留大量空白给文字标签
- 配色氛围:暖中性——灰米/燕麦/胡桃;安静高级、被阳光亲吻般、平静、杂志感。
  不要金色、不要冷调、不要高反差、不要油亮塑料感。

木纹和内衬色必须清晰可读——光线绝不盖住细节。写实产品摄影,自然内敛。正方形1:1。

Image A is the approved master scene. Image B is a different box variant.

Recreate Image A's scene EXACTLY — same greige limestone surface, same soft directional
sunlight, same light gradient, same shadow direction and softness, same camera angle,
same composition, same product position and scale.

Place the box from Image B into that exact scene. Keep Image B's box exactly as-is — its
shape, material, lid type, black-walnut grain, liner color and contents preserved
precisely. You may only enhance its material realism (soft matte finish, fine natural
grain detail, high clarity); change nothing about its design, proportions or color.
Do NOT invent or redraw the wood grain.

Photorealistic, identical look to Image A. Square 1:1.

⑤材质优化的边界:增强,不要重画

⑥要"自然一致",不要"工业克隆"

母版复制出来的图,周边不会像素级一模一样——AI 本来就有微随机,这恰恰是好事。

⑦测试微调旋钮

出图不对就改这几句,不用重写整段。

不做什么
