【负面tag】

1
nsfw, (EasyNegative), [[[[[bad-artist-anime, sketch by bad-artist]]]]], [[[mutation, lowres, bad hands, [text, signature, watermark, username], blurry, monochrome, grayscale, realistic, simple background, limited palette]]], close-up, (swimsuit, cleavage, armpits, ass, navel, cleavage cutout), (forehead jewel:1.2), (forehead mark:1.5), (bad and mutated hands:1.3), (worst quality:2.0), (low quality:2.0), (blurry:2.0), multiple limbs, bad anatomy, (interlocked fingers:1.2),(interlocked leg:1.2), Ugly Fingers, (extra digit and hands and fingers and legs and arms:1.4), (deformed fingers:1.2), (long fingers:1.2)

1. 常规tag写法

1.分隔：不同的关键词tag之间，需要使用英文逗号,分隔，逗号前后有空格或者换行是不碍事的
e.g. 1girl,loli,long hair,low twintails（1个女孩，loli，长发，低双马尾）

2.混合：WebUi 使用 | 分隔多个关键词，实现混合多个要素，注意混合是同等比例混合，同时混。
e.g. 1girl,red|blue hair, long hair（1个女孩，红色与蓝色头发混合，长发）

3.增强/减弱：有两种写法
第一种 (提示词:权重数值)：数值从0.1~100，默认状态是1,低于1就是减弱，大于1就是加强
e.g. (loli:1.21),(one girl:1.21),(cat ears:1.1),(flower hairpin:0.9)

第二种 (((提示词)))，每套一层()括号增强1.1倍,每套一层[]减弱1.1倍。也就是套两层是1.1*1.1=1.21倍，套三层是1.331倍，套4层是1.4641倍。
e.g. ((loli)),((one girl)),(cat ears),[flower hairpin]和第一种写法等价

4.渐变：先按某种关键词生成，然后再此基础上向某个方向变化。
[关键词1:关键词2:数字X]
(i) 数字大于1时: 第X步前为关键词1，第X步后变成关键词2;
(ii) 数字小于1时: 总步数的百分之X前为关键词1，之后变成关键词2。

e.g. a girl with very long [white:yellow:16] hair 等价为
开始 a girl with very long white hair
16步之后a girl with very long yellow hair

e.g. a girl with very long [white:yellow:0.5] hair 等价为
开始 a girl with very long white hair
50%步之后a girl with very long yellow hair

2. tag书写要点

  1. 将关键词控制在75个（100个）以内。
  2. 越关键的词，越往前放。
  3. 相似的同类，放在一起。
  4. 只写必要的关键词。

3. tag安排顺序
