拍摄人物坐姿时,需要注意:
- 选择一个舒适和自然的坐姿,符合个性和心情。可以坐在椅子、沙发、长凳、凳子或者地上。避免坐得太僵硬或者太懒散。放松肩膀和颈部,保持背部直但不僵硬。
- 根据相机的角度和距离调整腿和脚。可以交叉腿,弯曲一条腿,伸直另一条腿,把脚塞在身下,或者悬在座位的边缘。尽量在腿和身体之间留一些空间,避免看起来臃肿或拥挤。
- 用胳膊和手来增加姿势的多样性和表现力。可以把肘部放在膝盖上,托住下巴或脸颊,摸摸头发或衣服,或者用手指做一些手势。也可以使用道具,如一本书,一杯茶,一顶帽子,或一朵花,来创造兴趣和展示你的个性。避免把手平放在大腿上或藏在背后。
- 轻轻地倾斜或转动头部,创造一个更有吸引力和动态的外观。可以直视相机,或者看向一边,上方,或下方。也可以微笑,大笑,皱眉,或者做任何其他符合心情和风格的面部表情。避免看起来太严肃或无聊,除非这是想要的效果。
测试图像来源于 DreamShaper 第 8 版,人物坐姿,随机种子 931436911 。
1. 坐姿 (Sitting) 正向提示词
坐姿的正向提示词 (Prompt),不要追求提示词适用各种随机种子,提升概率即可:
bash
(masterpiece, best quality:1.2),highly detailed,extremely detailed,real photo,
fullbody,1girl,solo,asian,looking at viewer,(body facing viewer:1.2),
(relax sitting),knees separation,
red lips,brown long hair,
collared shirt and dress shirt,long sleeves,(knees length dress),
(240D wrap hip very thick pantyhose),color high heels,
good anatomy,good proportions,good pose,perfect legs,(pair shoes,pair legs:1.2),
nice hand,nice figure,
outdoors,buildings,
(photorealistic,realistic:1.2),
<lora:more_details:0.4>,<lora:control_skin_exposure:-1.0>,
<lora:yuzu_highheel_v2:0.5>,<lora:sit_cross_leg_v2:0.5>,
建议不要加入坐姿的细节描述,除非是配合特定 LoRA 的
sit cross leg
,其他细节都会影响身体结构,导致一些异常,让模型自由发挥即可。
具体分析:
- 基础质量关键词:
(masterpiece, best quality:1.2),highly detailed,extremely detailed,real photo,
- 全身人像:
fullbody,1girl,solo,asian,looking at viewer,
- 身体面向镜头:
(body facing viewer:1.2)
,避免侧坐导致的腿部重合,以及构图错误。 - 坐姿:
(relax sitting),knees separation,
,膝盖分离提示词,避免只出现单条腿。 - 面部:
red lips,brown long hair,
- 服装:
collared shirt and dress shirt,long sleeves,(knees length dress:1.1),
,长袖与过膝裙,减少腿部裸露 - 腿部:
(240D wrap hip very thick pantyhose),color high heels,
,包臀厚袜子避免出现不合适的袜子,增加高跟鞋的颜色。 - 姿态质量:
good anatomy,good proportions,good pose,perfect legs,(pair shoes,pair legs:1.2),,
,双鞋双脚,避免严重缺失。 - 腿部和手部质量:
nice hand,nice figure,
,好手是与负向提示词联用 - 环境:
outdoors,buildings,
- 风格:
(photorealistic,realistic:1.2),
- LoRA:
<lora:more_details:0.4>
,增加细节,注意不要权重过高,导致多腿多鞋现象,原因是坐姿比站姿更为近景,更多起始噪声,容易误生成其他信息。 - LoRA:
<lora:control_skin_exposure:-1.0>
,调整皮肤的暴露程度,解决大腿暴露的问题,权重-1
表示全部遮挡。 - LoRA:
<lora:yuzu_highheel_v2:0.5>
,增强腿部质量,注意权重不能过高,否则导致腿部畸形 - LoRA:
<lora:sit_cross_leg_v2:0.5>,
,增强腿部姿势,注意权重不能过高,否则导致腿部畸形。
在坐姿中,容易出现各种各样的畸形,使用两个 LoRA 控制腿部和坐姿质量,即
yuzu_highheels_1.0
与sit_cross_leg_v2
。

- DreamShaper 作者制作,非常好用,类似的还有
control_skin_exposure
:control skin exposure- 权重
-1
是全部遮挡。
- 权重
yuzu_highheel_v2
:yuzu high heel- 包括 2 个版本,推荐第 2 个版本下载量较大。
sit_cross_leg_v2
:Sitcrossleg (legs/shoes concept/helper)- 腿部交叉 (sit cross leg),不加这个关键字,也能优化其他坐姿。

坐姿的负向提示词 (Negative Prompt):
bash
(ng_deepnegative_v1_75t:1.3),(negative_hand),(badhandv4),
(negative_feet_v2:0.5),
body sideways,buttocks,
missing arm,missing leg,extra arms,extra legs,mutated legs,extra limbs,malformed limbs,floating limbs,disconnected limbs,
bad anatomy,bad proportions,disfigured,long neck,long leg,
worst quality,bad quality,jpeg artifacts,lowres,normal quality,low quality,
EasyNegative,
具体分析:
- Embeddings:
(ng_deepnegative_v1_75t:1.3)
,有效的修复混乱的四肢,提升权重。 - Embeddings:
(negative_hand),(badhandv4),
,修复手部且不影响画面。 - Embeddings:
(negative_feet_v2:0.5),
,修复腿部,但是权重不宜过高,影响图像。 - 姿态:
body sideways,
,避免侧身。 - 肢体:
missing arm,missing leg,extra arms,extra legs,mutated legs,extra limbs,malformed limbs,floating limbs,disconnected limbs,
,继续强化混乱的四肢。 - 身材比例:
bad anatomy,bad proportions,disfigured,long neck,long leg,
- 低质量:
worst quality,bad quality,jpeg artifacts,lowres,normal quality,low quality,
- Embeddings:
EasyNegative,
,补充其他负向提示词,建议放到最后,不干扰其他关键词。
Embeddings 的 Hash 值,TI,即Textual Inversion,文本反推:
TI hashes: "ng_deepnegative_v1_75t: 54e7e4826d53, negative_hand: 73b524a2da12, badhandv4: 5e40d722fc3d, negative_feet_v2: df90b1ff666d, EasyNegative: 66a7279a88dd"

2. 配置参数
标准配置如下:
- 采样方法:建议
DPM++ 2M SDE Karras
,比DDIM
更加融和。 - 放大算法:
4x-UltraSharp
- 其他是常用配置。
即:
开启脸部修复 ADetailer
,有些 LoRA 严重影响脸部,容易导致欧美人脸,添加提示词进行强化亚洲审美,即:
bash
asian girl, make up, beautiful face,
