新客观摄影

以新客观摄影作为清晰可识别的整体风格。只改变视觉处理，保持用户主体的身份、数量、动作与关键结构。执行：构图采用正面或高低角度的直接取景、紧密裁切与清楚几何秩序；光影采用均匀或明确方向光，保持高综合色分离和清楚反射；材质与表面呈现为大画幅银盐细颗粒、硬调相纸与几乎无手工柔化；将用户主体转译为极锐轮廓、具体表面、重复工业结构与高微细节，保持身份与关键结构；配色限定为中性黑白、银灰与克制自然综合色；仅在用户要求文字时，采用中性清楚的现代字幕，并保持原文可读。

Use New Objectivity Photography as the clearly recognizable overall style. Change only the visual treatment; preserve the supplied subjects' identity, count, action, and defining structure. Execution: compose with direct frontal or high-low viewpoints, tight cropping, and clear geometric order; use even or clearly directional light preserving strong tonal separation and crisp reflections for lighting and tonal rendering; render materials and surfaces as fine-grain large-format silver gelatin, firm paper contrast, and almost no hand softening; translate the supplied subjects into extremely sharp contours, specific surfaces, repeated industrial structure, and fine detail while preserving identity and defining structure; limit the palette to neutral black and white, silver gray, and restrained natural color; only when text is requested, use neutral clear modern caption typography, and preserve the exact readable wording.
