双层写实叙事编辑海报

高级编辑海报说明
每张上传的照片都必须分别转换为独立的高级编辑海报。绝不将多张照片合并到同一设计中。使用严格的 3:4 竖幅画布，在正中心沿水平方向划分为两个等大的部分，每部分占总高度的 50%，并占据全部宽度，不得改变比例。

上半部分必须直接使用原始照片，不得重新生成。准确保留主要主体的身份、人体解剖结构或建筑结构、比例、透视、空间关系、纹理、自然光线、阴影、色彩和环境。只允许轻微裁剪以及克制的高级调色。不得重绘主要主体、引入人工光、使用过度HDR或饱和度、制造塑料质感或添加虚构元素。如有必要，只能延展天空、水面、地面、墙壁、植物或背景等环境区域。

下半部分必须重构照片的核心叙事，无论是单一主要主体，还是代表图像身份、尺度、动作或故事的关联元素组合。保留真实外观、可辨识的身份、比例、内部结构、纹理和相对位置。不得移除重要的相关元素，也不得使用矩形照片剪贴。重构后的主体应约占下半部分宽度的 55%–80%。根据场景方向自然延展主体，保持可信的地面接触、水线、真实阴影或柔和渐隐的边缘。将其无缝融入背景，避免贴纸般或悬浮的外观。

在主体后方或穿过主体的位置放置一块狭窄、低饱和度的几何色块，在摄影写实与编辑抽象之间形成细微过渡。从原始照片中提取颜色，并根据场景的叙事方向选择水平、垂直或对角线方向。主体必须明显穿过色块边界，一部分与色彩区域重叠，另一部分延伸到开放的负空间中。营造自然的遮挡、重叠和空间深度。色块不得充当边框或卡片，也绝不能完全包围主体。仅使用一个主要几何窗口。不得添加多个色块、粗边框、圆角、强渐变或投影。

下半部分使用白色、冷白色、极浅灰色或近白色背景，并与原始照片协调。保持克制的不对称构图，提供充足的负空间和清晰的视觉层级：重构主体为主要焦点，低饱和度几何窗口为次要元素，干净背景为空间支撑。

最终海报必须显得高级、精致、真实且具有编辑感，同时保留原始照片的视觉身份、严格的双层构图、原始比例和整体艺术方向。

Premium Editorial Poster Instructions
Each uploaded photo must be transformed into a separate, independent premium editorial poster. Never combine multiple photos into one design. Use a strict 3:4 vertical canvas divided horizontally at the exact center into two equal halves, each occupying 50% of the total height and full width, without altering proportions.

The upper half must use the original photo directly without regeneration. Preserve the main subject's identity, human anatomy or architectural structure, proportions, perspective, spatial relationships, textures, natural lighting, shadows, colors, and environment exactly as shown. Only slight cropping and restrained premium color grading are permitted. Do not redraw the main subject, introduce artificial lighting, apply excessive HDR or saturation, create plastic textures, or add fictional elements. If necessary, extend only environmental areas such as the sky, water, ground, walls, plants, or background.

The lower half must reconstruct the photo's central narrative, whether it is a single primary subject or a connected group of elements representing the image's identity, scale, action, or story. Preserve realistic appearance, recognizable identity, proportions, internal structure, texture, and relative positioning. Do not remove important related elements or use a rectangular photo cutout. The reconstructed subject should occupy approximately 55%–80% of the lower half's width. Extend the subject naturally according to the scene's direction, maintaining believable ground contact, waterlines, realistic shadows, or softly fading edges. Integrate it seamlessly into the background without a sticker-like or floating appearance.

Place one narrow, low-saturation geometric color field behind or partially through the subject, creating a subtle transition between photographic realism and editorial abstraction. Extract the color from the original photo and choose a horizontal, vertical, or diagonal orientation according to the scene's narrative direction. The subject must visibly cross the color field's boundary, with part overlapping the colored area and another part extending into the open negative space. Create natural occlusion, overlap, and spatial depth. The color field must not act as a frame or card and must never completely enclose the subject. Use only one primary geometric window. Do not add multiple color blocks, thick borders, rounded corners, strong gradients, or drop shadows.

Use a white, cool-white, very light gray, or near-white background in the lower half, coordinated with the original photograph. Maintain a restrained asymmetrical composition with generous negative space and a clear visual hierarchy: the reconstructed subject as the primary focus, the low-saturation geometric window as the secondary element, and the clean background as supporting space.

The final poster must look premium, refined, realistic, and editorial while preserving the original photo's visual identity, exact two-half composition, original proportions, and overall artistic direction.
