【AI绘画】捕捉光影之美：探索肖像画的魅力
在AI绘画领域，光影效果的运用对于人物肖像的表现至关重要。不同的光源角度和性质能够塑造人物的立体感，表达情感和氛围。本文将通过Flux.1的AI人像作品，深入探讨逆光、顶光、侧光等光影效果在AI绘画中的应用。
不论是学设计、摄影还是基础素描，甚至是任何和艺术沾边的朋友，都对作品中光影建立有一套概念。这种因为光即是一切物体“形”的灵魂！光影对于人物肖像的表现至关重要，它不仅可以塑造人物的立体感，还能表达情感和氛围。通过不同的光源角度，如逆光、顶光、侧光等，光影能改变人物的面部特征、情绪表达以及整个画面的视觉冲击力。

然而，不同位置、方向、光量强弱，光色等等物理属性光的存在，决定了照射主体的感觉。今天，我们结合Flux.1来看看光影在AI人像图片中是如何"画龙点睛“的。
逆光（Backlighting）
特征：光源位于主体后方，产生强烈的轮廓光，形成对比鲜明的边缘光效。
适用场景：适合创造梦幻效果或突出主体的轮廓，常用于日落时分的户外摄影。
提示词：White text reading ‘Backlighting’ in a stylish, readable font in the center of the bottom. A photograph of a young Chinese woman facing the camera, dramatically backlit by the setting sun. The warm, golden light creates a halo effect around her figure, casting long shadows across a vast desert landscape. Golden hour lighting, dramatic shadows, intense contrast, cinematic style, warm tones, ultra-realistic, 8K resolution.
顶光（Top lighting）
特征：光源从上方垂直照射，创造出强烈的阴影效果，尤其是在主体下巴和眼睛下方。
适用场景：用于强调形状和体积感，适合中午阳光下的自然摄影或舞台灯光。
提示词：White text reading ‘Top Lighting’ in a stylish, readable font in the center of the bottom. A photograph of a young Chinese woman facing the camera, illuminated from above by strong sunlight at noon. The harsh top lighting creates bold shadows on her face and body, with deep contrast between the illuminated and shaded areas. The landscape appears flat and dry, with intense sun overhead, creating a stark and dramatic effect. High contrast, warm tones, ultra-realistic, 8K resolution.
侧光（Side lighting）
特征：光源来自侧面，产生深邃的对比，强调主体的纹理和立体感。
适用场景：适用于肖像和静物摄影，能凸显面部轮廓和细节。
提示词：White text reading ‘Side Lighting’ in a stylish, readable font in the center of the bottom. A photograph of a young Chinese woman facing the camera, illuminated from the side by soft, angled sunlight. The side lighting accentuates the contours of her face and body, creating deep shadows on one side and strong highlights on the other. The desert background is bathed in warm tones, with shadows stretching long across the ground. Cinematic style, dramatic depth, ultra-realistic, 8K resolution.
柔光（Soft lighting）
特征：柔和、均匀的光线，减轻阴影，创造出平滑的过渡。
适用场景：常用于人像摄影，适合营造温暖、柔和的氛围。
提示词：White text reading ‘Soft Lighting’ in a stylish, readable font in the center of the bottom. A photograph of a young Chinese woman facing the camera, bathed in soft, diffused light during the late afternoon. The gentle lighting creates smooth, even shadows, softening her features and the surrounding desert landscape. The warm, golden tones enhance the serene and peaceful atmosphere. Minimal contrast, gentle shadows, cinematic style, ultra-realistic, 8K resolution.
硬光（Hard lighting）
特征：强烈的、直射的光线，产生鲜明的阴影和高对比。
适用场景：用于强烈、戏剧性的效果，适合强调细节和纹理的场景。
提示词：White text reading ‘Hard Lighting’ in a stylish, readable font in the center of the bottom. A photograph of a young Chinese woman facing the camera, lit with sharp, direct sunlight, casting hard, defined shadows on her face and body. The harsh lighting creates a stark contrast between the light and shadow, emphasizing the texture of the desert sand and the intensity of the sunlight.
