关于NovelAi的相关知识点总结

10月10日，我开始接触ai绘画相关方面的内容，对于偏向二次元方向NovelAi进行了一番探索，此处将一些要点写于下方

咒语(tag)

在AI绘画中，tag标签对于创作是绝对的核心，在NoveAi中，创作分为正面tag（希望出现的）和负面tag（不希望出现的），每一个独立的tag用逗号分割开来。
由于ai常常会对于用户的标签有一些诡异的，超乎想象的，甚至颠覆性的理解(尽管绝大部分是用户自己思考的不到位，吧？)。犹如克苏鲁的信徒们在和不可名状的主进行着沟通，来获取自己心爱的老婆们。所以，我觉得用咒语来形容tag也很贴切。

如图，上方为正面tag，下方为负面tag

防护咒术（负面tag）

负面tag为什么要在正面tag前面介绍？因为我相信大部分温和善良的宅宅们一定不想看到自己花费心思构思半天的老婆们变成了三头六臂的贵物（当然，少数性癖群体当我没说）。
正面tag通常只会指出，用户需要的属性，然而这常常不会把构造一个人需要的要素全部考虑的明明白白（更何况目前还有75长度的限制）。所以，ai会试着用自己的理解去补全一幅画，所以，我们得严厉的警告它，你，不能画三条手，三只腿，三个眼睛，不能乱打光！！！！
值得一提的是，防护咒语通常不会有用户花费心思去构建，所以本文提供了3串通用的咒语，供大伙直接贴过去用
邪神防护咒语范例:

1.lowres, bad anatomy, bad hands, text, error, missing fingers, extra digit, fewer digits, cropped, worst quality, low quality, normal quality, jpeg artifacts, signature, watermark, username, blurry
(稳定，好用，全网流通，第一选择)

2.mutated, two persons, bad quality, 2 girls, 2 faces, lowres, bad anatomy, bad hands, text, error, missing fingers, extra digit, fewer digits, cropped, worst quality, low quality, normal quality, jpeg artifacts, signature, watermark, username, blurry ,disfigured
(稳定，重点的强调了画面中只允许一个人的存在)

3.{{poorly drawn hands}}, {{poorly drawn face}}, {{{mutation}}}, {{{deformed}}}, {{ugly}}, blurry, {{bad anatomy}}, {{{bad proportions}}}, {{extra limbs}}, cloned face, {{{disfigured}}}, {{{more than 2 nipples}}}, {{{**}}}, out of frame, ugly, extra limbs, {bad anatomy}, gross proportions, {malformed limbs}, {{missing arms}}, {{missing legs}}, {{{extra arms}}}, {{{extra legs}}}, mutated hands, {fused fingers}, {too many fingers}, {{{long neck}}}, missing fingers, extra digit, fewer digits, bad feet
（不稳定，上下限波动极大，但是有时候效果比上面两个强）

4.lowres，bad anatomy, bad hands, text, error, missing fingers, extra digit, fewer digits, cropped, worst quality, low quality, normal quality, jpeg artifacts, signature, watermark, username, blurrypolar lowres,bad anatomy,bad hands,bad body,bad proportions,gross proportions,text,error,missing fingers,missing arms,missing legs,extra digit,extra fingers,fewer digits,extra limbs,extra arms,extra legs,malformed limbs,fused fingers,too many fingers,long neck,cross-eyed,mutated hands,cropped,poorly drawn hands,poorly drawn face,mutation,deformed,worst quality,low quality,normal quality,jpeg artifacts,signature,watermark,username,blurry,ugly,duplicate,morbid,mutilated,out of frame,body out of frame/{mutated hands and fingers :1.5},{long body :1.3},{mutation ,poorly drawn :1.2}bad anatomy disfiguredmalformed mutated,More than two breasts{bad feet} Transgender, Penis girl，extra nipple, extra breast,out of frame, amputee, mutated, mutation, deformed, severed, dismembered, corpse, poorly drawn, bad anatomy, blur, blurry, lowres, bad hands, error, missing fingers, extra digit, fewer digits, cropped, worst quality, low quality, normal
(大魔导防护咒语，未实验)

关于重音方式:
使用符号 {}. 你可以添加许多花括号来强调某个元素.
添加detailed前缀来强调某个局部细节, 比如detailed face.

祈祷咒术(正面tag)

在打下了防护邪神的底子后，终于要开始正式的求老婆祈祷了，

在开头添加: best quality, masterpiece, highres, original, extremely detailed wallpaper(尤其是前三者)
能有效的防止ai试图摸鱼的行为，提高质量

对于强调的重点，你需要{}框起来，可以通过{}的数量的提醒权重占比

值得一提的是，这个ai并没有那么死板，对于每一个tag，你不一定要输入单一的概念，你可以输入：在樱花树下奔跑，在椅子上吃饭，在水上开枪。 他们都可以被ai理解，甚至，你可以试图输入诗句来召唤老婆(当然，内容尽量不要太虚幻了~~)。
“Her hair is shallow ice blue, flying in the wind, cherry blossom wrapped around his hair, appears particularly enchanting. Orange eyes like the dazzling sun, people obsessed. Pointy ears peeped out of the whiskers, lovely and playful. The protein is shiny, longer and thicker than anyone’s eyelashes. Lips thin and red, like the enchanting cherry blossoms, people can not help but want to occupy. Standing under the cherry blossom trees, he is like a star in the night sky, burning eyes and far behind.”
“她的头发是浅冰蓝的，在风中飞舞，樱花缠绕着他的头发，显得格外迷人。橙色的眼睛像耀眼的太阳，让人着迷。尖尖的耳朵从胡须里露出来，可爱又好玩。这种蛋白质比任何人的睫毛都有光泽、更长、更厚。嘴唇薄而红，像迷人的樱花，人们不禁想占据。站在樱花树下，他像夜空中的一颗星星，燃烧着眼睛，远远地落在后面。”

由于该AI有较为强大的文字理解能力，正面咒语中，有全局性的tag（如：各种风格，杰作，电影化打光），也有细小的人设细节（白丝，黑丝，发饰，军服），它都能进行识别的描绘，但是切记，尽量不要让tag出现冲突，如多种的风格，多种打光方式，甚至让ai一边双手摆pos一遍掀起裙子，这样你就可能看见"薛定谔的裙子"

总体介绍完毕,下文记录了一些较为有用的咒语

一些强大的词条
