有人说：光影是摄影的灵魂，能够赋予摄影图像迷人的质感，能够注入创作者所需要表达的情绪。巧妙地操控光线，可以使图像中的摄影主体更加突出，增加主题的深度和视觉震撼，唤起读者的情感和强调摄影关键细节。

在今天这份SD必备知识系列中，我们将深入探讨多种光影提示语来操控光影的示例效果，当然针对不同模型可能存在不同的差异，需读者自主尝试。另外推荐ControlNet作者最新打光模型：IC-Light：图像打光控制和背景融合生产力工具，最全ComfyUI操作指南。

在SD绘图中，常见的光影关键有如下几种：

• 体积光（Volumetric lighting）：在提示词中注入“体积光”的魔力，可以召唤出空灵的光束。

• 边缘光（Rim lighting）：通过使用“边缘光”为图像中的主体勾勒出柔和的光环，增添一丝神秘感。

• 阳光（Sunlight）：通过加入“阳光”，唤起黄金时刻的温暖，让图像中主体沐浴在自然的光辉中。

• 逆光（Backlight）：通过将光源置于主体后方，创造出令人敬畏的效果，并强调它们的轮廓。

• 昏暗光线（Dimly lit）：通过将“昏暗光线”编织加入提示词，引入一种神秘和微妙的氛围。

• 黄昏光线（Crepuscular rays）：通过召唤“黄昏光线”，用戏剧性的光束描绘您的构图，点燃视觉的辉煌。

• 柔和光线（Soft light）：柔和光线，展示温馨柔和环境。
