黄昏窄巷纪实摄影 AI 提示词，暖橙与深黑强对比画面

Vertical documentary photograph of a narrow alley at dusk, the strongest visual anchors being the extreme light-dark contrast and the warm orange versus deep black two-color relationship. In the center a narrow alley recedes into depth, the left side a rough grey brick wall with visible mortar joints, struck by a slanted warm orange low sun from the upper right, creating a sharp diagonal boundary between light and shadow, the upper half sinking into deep black while the lower half glows orange-gold. Midway along the left wall is a small dark window with an air-conditioning unit mounted above it, thin pipes running diagonally down the wall below. The right side is an almost entirely black wall or doorway structure, only its lower edge faintly lifted by ground reflection, acting as a dark framing element. Above, dense tree canopy closes in from both sides, leaves rendered as dark silhouettes against the backlight with tiny warm rim highlights, casting dappled patches and long diagonal shadows onto the brick wall and ground. The ground is rough asphalt or stone paving, the lit portion orange-gold, contrasting with large deep black shadows in the foreground, a pale curb stone running along the perspective line toward the distance. At the far end of the alley a bright pale sky and blurred distant building outlines form a visual exit. Eye-level camera, natural perspective, wall and ground lines converging toward the distance, noticeable spatial compression, the large dark foreground anchoring the bottom of the frame. Low-angle side-backlight, hard light, very high contrast ratio, warm orange highlights and near-black shadows, medium-high saturation concentrated in orange-gold and dark green. Slight grain and film texture, some detail retained in shadows, soft highlight edges. In the lower right corner a semi-transparent watermark text 「贴图号·建国5866」.
