高级编辑海报制作说明

Premium Editorial Poster Instructions Each uploaded photo must be made into a separate, independent, premium editorial poster, and multiple photos must not be combined. Use a strict 3:4 vertical canvas. Split the canvas horizontally in the exact center: the upper half and the lower half each occupy 50% of the height, are equally wide, and equally high, with no alteration of proportion. The upper half uses the original photo directly and must not be regenerated. Preserve the identity of the main subject, the human body or architectural structure, proportions, perspective, spatial relationships, texture, natural light and shadow, color, and environment in their entirety. Only slight cropping and restrained premium color grading are permitted; re-drawing the main subject, fictional light, HDR, excessive saturation, plastic texture, and fictional content are prohibited. When needing to adapt to the frame, only environmental areas such as sky, water surface, ground, walls, plants, or background can be extended. The lower half extracts and reconstructs the "narrative core" of the photo: it can be a single primary subject, or a group of related elements that together embody the photo's identity, scale, action, o story relationship. Maintain its realistic, recognizable appearance, proportion, internal structure, texture, and relative position. Do not remove important related elements, and do not directly use rectangular photo cutouts. The reconstructed subject typically occupies 55%-80% of the width of the lower area. It should naturally extend based on the photo's primary direction and retain plausible ground, water lines, shadows, or softly dissipated edges to integrate into the background, avoiding a sticker-like or floating appearance. Incorporate a narrow, low-saturation geometric color field behind or through the center of the subject, serving as a "critical window" between reality and editorial abstraction. The color of the window must be extracted from the original photo, and its orientation (horizontal, vertical, or diagonal) chosen based on the overall narrative direction. The subject must actively pass through the window: part of it is within the color field, and part enters the open negative space, naturally crossing the window's boundary to create occlusion, penetration, and spatial depth. The window is not a frame or a card; it must not fully enclose the subject. Only one primary window is allowed; multiple color blocks, thick borders, rounded corners, strong gradients, and drop shadows are prohibited. Use a white, cool white, very light gray, or near-white background for the lower half, coordinated with the photo. Employ a restrained asymmetrical composition and abundant negative space to establish a three-tier hierarchy: Reconstructed subject or narrative composition Low-saturation geometric window

高级编辑海报制作说明 每张上传的照片必须制成独立的高级编辑海报，不得将多张照片合并。使用严格的 3:4 纵向画布。在正中央横向分割画布：上半部分与下半部分各占 50% 的高度，宽度相同、高度相同，不得改变比例。 上半部分直接使用原始照片，不得重新生成。须完整保留主体的身份、人体或建筑结构、比例、透视、空间关系、纹理、自然光影、色彩和环境。仅允许轻微裁剪和克制的高级调色；禁止重绘主体、虚构光线、HDR、过度饱和、塑料质感和虚构内容。如需适配画面，只能延伸天空、水面、地面、墙壁、植物或背景等环境区域。 下半部分提取并重建照片的"叙事核心"：可以是单一主体，也可以是一组相关元素共同体现照片的身份、规模、动作或叙事关系。须保持其真实可辨的外观、比例、内部结构、纹理和相对位置。不得移除重要的相关元素，也不得直接使用矩形照片裁剪。重建主体的宽度通常占下半部分宽度的 55%-80%。它应根据照片的主要方向自然延展，并保留合理的地面、水线、阴影或柔和消散的边缘以融入背景，避免贴纸式或悬浮外观。 在主体背后或穿过主体中心处嵌入一个窄而低饱和度的几何色块，作为现实与编辑抽象之间的"关键窗口"。窗口颜色必须从原始照片中提取，其方向（水平、垂直或对角）根据整体叙事方向选择。 主体必须主动穿过窗口：部分位于色块之内，部分进入开放负空间，自然跨越窗口边界以形成遮挡、穿透和空间纵深。窗口不是画框或卡片，不得完全包裹主体。仅允许一个主要窗口；禁止使用多个色块、粗边框、圆角、强渐变和投影。 下半部分使用白色、冷白、极浅灰或近白背景，与照片协调。采用克制的非对称构图和大量负空间，以建立三层层次： 重建主体或叙事构图 低饱和度几何窗口
