在使用Stable Diffusion等AI图像生成模型时，通过指定视角（viewpoint）可以控制图像中物体或场景的呈现方式。视角的选择能够极大地影响图像的视觉效果和情感表达。以下是一些专业的提示词，可以帮助你指定不同的视角：
视角类型
- 鸟瞰/俯视：
aerial view, bird's eye view, top-down, looking down, overhead - 平视：
eye level, straight-on, frontal, direct, face to face - 仰视：
low angle, looking up, upward, from below, worm's eye view - 侧视：
side view, profile, lateral, from the side, oblique - 特写/近距离：
close-up, macro, zoom in, detailed, intimate, tight shot - 远景/远距离：
long shot, wide shot, panoramic, distant, landscape, overview, far away - 透视/纵深感：
perspective, vanishing point, depth, 3D, three-dimensional, leading lines, converging lines - 倾斜/斜视：
tilted, canted, Dutch angle, diagonal, off-kilter, slanted
摄影与电影术语
- 过肩镜头：
over-the-shoulder, OTS, behind the shoulder, framing with a subject's shoulder - 跟随镜头：
tracking shot, dolly shot, moving with the subject, smooth motion, camera following - 推拉镜头：
push-in, pull-out, zoom in, zoom out, moving closer or further, dynamic change in distance - 摇摄：
panning, horizontal movement, sweeping across, left to right, right to left - 倾斜移动：

其他描述性词汇
- 聚焦点：
focus, focal point, center of attention, main subject, highlight, emphasized area - 景深：
depth of field, shallow, deep, background blur, bokeh, selective focus - 构图：
composition, rule of thirds, symmetry, asymmetry, balance, framing, negative space, leading lines, contrast
示例
当你想要一个特定视角的图像时，可以在你的提示词中加入上述关键词。例如，如果你想要一张从低角度拍摄的城市天际线图片，你可以这样描述：
“A city skyline with tall skyscrapers and bright lights, captured from a low angle, looking up, with dramatic perspective and strong vanishing points.”或者，如果你想得到一幅自然风光的特写照片，你可以使用这样的提示词：
“A close-up of a blooming flower, with dewdrops on the petals, taken at eye level, focusing on the intricate details and textures, with a shallow depth of field to create a soft background blur.”记住，具体的提示应该根据你所期望的画面内容来定制。尝试结合多个视角相关的提示词，以获得更加丰富多样的视觉效果。此外，实验和迭代是找到最佳结果的关键，可能需要几次尝试才能得到最满意的结果。
