照片抽象编辑
把一张照片变成一张竖向编辑海报：上方忠实保留原片气质，下方象牙色面板只保留从原片提炼出的空间关系和色彩，再配一行诗意英文标题。
何时使用
- 用户上传了一张照片并说「帮我做成抽象编辑风格」「做成那种照片+抽象画的海报」「提炼一下这张图」「想印成海报」
- 题材适合：建筑、城市街景、自然风光、人群剪影、旅行照、静物、室内光影
- 不适合：头像精修、卡通/插画、文字海报、需要保留完整文字/商标的设计
使用方法
- 用户上传一张照片（或提供本地路径/URL）
- 在对话中说：「用照片抽象编辑处理这张照片」或「把它做成摄影+抽象面板的海报」
- 系统自动调用 WorkBuddy ImageGen，并把照片作为输入图传入
- 返回一张完整竖向作品
工作流（内部执行）
- 观察照片：提取 3–6 个决定性空间事实——主体位置、大小比例、方向/轴线、重复节奏、遮挡层级、前后景深、明暗/色彩角色、负形。
- 保留原片：上方摄影区域必须忠实展示原片主体、光线、颜色与空间关系；只允许为整体比例做克制的等比缩放或轻微裁切，不得重画、扩展、替换、修饰或加滤镜。
- 抽象重构：在下方象牙色面板中，用最少标记重建被保留的关系。优先保留「关系」而非「轮廓」；标志性建筑或独特形状最多保留 1–3 个身份线索；人群用不规则短竖墨点/色块表示，不画头脸四肢。
- 自适应拼接：根据原片方向与重心决定摄影区/面板区比例；横向延展照片摄影区约占 38%–52%，高耸建筑/人物约占 55%–68%，接近方形约占 48%–58%。两区直接平面衔接，无框、无阴影、无撕纸、无样机。
- 标题命名：创作 2–5 个英文单词的原创标题，必须对应照片真实关系或视觉事实；可选 3–7 词副标题，但只在新语义层出现时加入。
- 标题排版：标题放在象牙面板内、抽象母题下方或侧边；主标题用克制优雅的衬线体，颜色取自照片主体深色；不得把标题放进照片区或画布边缘。
调用 ImageGen 的参数
- 工具：
ImageGen size：默认"1024x1536"（竖向），若原片比例明显不同可改为"1536x1024"或"1024x1024"，但优先竖向。quality："high"image：传入用户上传的图片路径/URLinput_fidelity："high"（尽量保留原片气质）prompt：使用下方模板编译出的最终英文提示词
提示词编译器
把观察到的事实填入 [ ] 处，按以下 6 段顺序组装成最终 prompt，禁止调换顺序或合并段落。
A clean vertical editorial artwork composed of two joined sections: an upper faithful photographic region and a lower flat ivory abstract memory panel. No frame, no shadow, no mockup, no collage tape, no border between sections. The two regions meet with a direct flat seam.
[PHOTO_REGION]
Keep the uploaded photograph as the upper or principal section of the composition. Render it faithfully: preserve the main subject, light, colors, spatial relations, and photographic mood. Allow only proportional scaling or a slight crop for overall balance. Do not redraw, repaint, extend, replace, retouch, filter, stylize, or alter the photo content.
[ABSTRACT_PANEL]
Below the photo is a uniform, untextured ivory panel (#F3F0E8). On this panel reconstruct only the most essential spatial relationships observed in the photo as a sparse abstract motif. Use one primary mark family and at most two supporting families. The motif should occupy roughly 30%–42% of the panel width and 28%–34% of the panel height, leaving 65%–80% clean ivory space. Adapt the motif scale and position to the photo: horizontal subjects may stretch wider; tall landmarks may grow taller but never fill the panel.
Spatial facts to encode: [list 3–6 decisive facts such as subject position, scale axes, direction, intervals, repetition, overlap, depth, light, color roles, negative space]. Reduce each fact to a minimal mark: flat or gently organic masses, soft circles, arcs, tapered blocks, short bars, layered bands, or simplified architectural masses. Supporting marks may include thin axes, short vertical dashes, isolated dots, or restrained human silhouettes. Every mark must trace back to a real visual fact in the source photo. Avoid decorative symmetry, patterns, invented symbols, icons, or generic illustrations.
[COLOR_SYSTEM]
Extract a muted palette solely from the photo: one primary color role, one dark structural role, one light/neutral role, and at most one small accent color. Do not add neon, complementary colors without source, or multiple competing accents. The abstract marks use these reduced photo colors against the flat ivory background.
[TITLE]
Place one original English title of 2–5 words on the ivory panel, below or beside the abstract motif. Title must be grounded in visible facts from the photo and feel poetic but not sentimental. Use an elegant, restrained editorial serif face. Title color should be a deep, subdued color from the photo subject (dark blue-gray, dark green, wine, deep purple, charcoal). Do not use pure black by default. No extra text, dates, numbers, logos, or watermarks.
[CLEAN_MODE]
The ivory panel must be completely flat and continuous: no gradients, no paper texture, no grain, no shadows, no glow, no vignette, no stains, no scan effects, no seams. The abstract marks may have slightly natural edges but must not rely on texture or noise for atmosphere. Atmosphere comes only from whitespace, distance, pause, asymmetry, scale differences, limited marks, and a restrained palette.
HARD AVOID: photo redraw, scene reconstruction, outpainting, filter effect, posterized photo, vector trace, full illustration, regularized infographic, generic icon, dense decoration, fictional content, forced symmetry, non-uniform background inside the ivory panel, realistic small objects, excessive architectural detail, capsule-shaped human figures, candidate title lists, extra text, product ad, cinematic lighting, neon, 3D render, anime, cartoon, glossy effect.
根据题材调整抽象程度
| 题材 | 处理建议 |
|---|---|
| 普通场景、自然景观、光影、地平线、水面、人群 | 保留方向、密度、间隔、层级、运动与色彩关系，不保留完整轮廓 |
| 标志性建筑或独特形状主体 | 保留 1–3 个最低限度身份线索（外轮廓、拱洞、尖顶、层叠节奏），不画窗户、砖石、斗拱 |
| 有机群体（气球、树冠、云团、灯光） | 用重叠柔和色块表达密度与扩散/聚集，不画内部图案与高光 |
| 人群 | 每人用一个连续不规则短竖墨点或轻微收分色块，头肩一体，不画头脸四肢 |
| 栏杆、道路、地平线、水岸 | 压缩为 1–2 条细水平轴和少量不规则中断 |
| 小型物件（铃铛、灯笼、风铃） | 保留 2–3 个平面标记，靠比例和位置建立辨识，不画金属高光与体积 |

偏离时的修正指令
如果首次生成不符合风格，用以下短句追加到下一轮 prompt：
- 照片被重画/风格化：追加
Keep the upper photo region strictly photographic and unfiltered; do not repaint, stylize, or add illustration-like edges. - 抽象面板出现纹理/渐变：追加
The lower panel must be a single flat continuous ivory (#F3F0E8) color; no gradients, no paper texture, no grain, no shadows. - 抽象母题太像缩略图/插画：追加
Abstract motif is not a thumbnail, trace, or icon; it should encode only spatial relationships, preserving minimum recognition cues. - 标题不在面板内/字体不对：追加
Place the English title only on the ivory panel, below the abstract motif, in a restrained editorial serif typeface. - 出现额外文字/色卡/水印：追加
Remove all extra text, color swatches, labels, dates, numbers, signatures, and watermarks.
能力边界
- 不保证 100% 保留原片像素级一致；ImageGen 会基于照片重新生成整体构图，但应保留照片气质与主要关系。
- 若用户上传的照片本身带有大量文字、商标、密集 UI，输出可能难以清理，建议先裁剪。
- 该风格偏向克制、留白、编辑感；喜欢繁复装饰或高饱和商业风的用户可能觉得过于清淡。
