一张图片的构图，往往是我们对其作出“美”或“不美”判断时，一个至关重要却常被忽略的环节。
“这张图，不知为何就是很美。” “看着它，内心感到一种莫名的平静。”
这种瞬间产生的无意识印象，与构图有着密不可分的关系。
您或许会认为，通过提示词来精确指定构图，对于AI而言是否过于苛刻？事实恰恰相反，在AI绘画中实现电影导演级别的专业构图，其实相当直接。
而我们今天要介绍的核心秘诀，便是——
“三分割构图法”！
什么是三分割构图法
三分割构图法是摄影、绘画及设计领域中广泛应用的基础构图原则。
其方法十分简单：将画面沿纵向与横向各作三等分，形成一个“九宫格”。利用这个网格，我们便可以更加均衡、和谐地安排画面主体的位置。
您在使用手机拍照时，是否会开启网格线功能？那正是三分割构图法的直观应用。可以说，三分割法是摄影界的“黄金比例”。
即便是使用数码相机，只要有意识地将被摄主体置于网格线的交点上，便能创作出视觉焦点明确、引人入胜的优美照片。
这个技巧，在AI绘画中同样能够轻松实现！
我们先来看一组直观的对比。
一张常规居中构图的图像
一张应用了三分割构图的图像
EN:
- A savannah scene framed using the rule of thirds composition. The right third of the frame depicts a standing meerkat. The left two-thirds of the image displaya vast horizon and savannah vegetation bathed in the warm golden light of the evening golden hour.
中:
- 一幅采用三分割构图的萨凡纳草原景象。画面的右三分之一描绘了一只站立的狐獴。画面的左三分之二展示了广阔的地平线和沐浴在傍晚金色时刻温暖光芒下的草原植被。
区别显而易见。在使用三分割构图的版本中，主体（狐獴）被精准地放置在视觉交点上，而广阔背景的平衡感也得到了恰当的处理。这种布局将视觉焦点引向了最富吸引力的位置，让观者的目光自然而然地被主体所捕获。

💡 创意构想 1
模特的一只眼睛被放置在三分割构图上部线条的交点上。
EN:
- An eye-level shot using the rule of thirds composition. The model’s one eye is placed at the intersection of the upper third line in the rule of thirds grid. The subject is an 18-year-old extremely cute Chinese woman with a sleek, straight bob haircut. She is dressed in a white down jacket, standing in a foreground where snow is actively falling. The background features a vibrant blue sky stretching across the frame. Bright natural light illuminates the scene, making the vibrant blue of the sky and the falling snow pop, while highlighting the model’s clear and radiant skin. The overall color palette is natural and fresh, combining the pure white of the snow with the vivid blue of the sky. A medium telephoto lens Canon RF 85mm f/1.2L USM is used, keeping the model sharply in focus while softly blurring the background. The final image is realistic and vibrant, rendered in ultra-HD 8K quality.
中:
- 采用三分割构图的平视拍摄。模特的单眼位于三分割网格上三分之一线的交点处。主体是一位18岁的、极其可爱的中国女性，留着顺滑的直发波波头。她身穿白色羽绒服，站在雪花纷飞的前景中。背景是横贯画面的鲜艳蓝天。明亮的自然光照亮了整个场景，使天空的湛蓝和飘落的雪花更加突出，同时也凸显了模特清澈透亮的肌肤。整体色调自然清新，雪的纯白与天空的鲜蓝融为一体。使用中长焦镜头佳能RF 85mm f/1.2L USM，使模特保持清晰对焦，同时轻微模糊背景。最终图像逼真且充满活力，以超高清8K质量呈现。
进阶技巧：框架式构图

核心提示词
- (由XXX构成框架的人像)
此技巧通过运用场景中的现有元素作为“画框”来包围主体，从而创造出视觉冲击力强烈、焦点高度集中的影像。
一些应用范例:
-
自然物框架 (Framing with Natural Elements): 用树枝、树叶包围主体。 -
建筑框架 (Framing with Architecture): 利用门框、窗框将主体置于其中。 -
光影框架 (Framing with Light and Shadow): 用阴影或聚光灯的光线来聚焦主体。 -
人物或物体框架 (Framing with People or Objects): 用他人的剪影或手来包围主体。
