Stable Diffusion - Prompts prompt word engineering framework

Welcome to my CSDN: https://spike.blog.csdn.net/
This article address: https://spike.blog.csdn.net/article/details/131544508

The current Stable Diffusion model uses the base stable-diffusion-v1-5 , v1-5-pruned-emaonly.safetensors .

Stable Diffusion's positive prompts are a language used to describe the images you want to generate, and you can control the content, style, and quality of the generated images through different words, symbols, weights, and correlations. Positive prompts can be flexibly selected and combined according to different scenarios and needs to achieve the desired effect.

Combining forward prompts with reverse prompts, the output effect is better. Reverse prompt words, as follows:

NSFW,(worst quality:2),(low quality:2),(normal quality:2),lowres,normal quality,((monochrome)),((grayscale)),skin spots,acnes,skin blemishes,age spot,(ugly:1.331),(duplicate:1.331),(morbid:1.21),(mutilated:1.21),(tranny:1.331),mutated hands,(poorly drawn hands:1.5),blurry,(bad anatomy:1.21),(bad proportions:1.331),extra limbs,(disfigured:1.331),(missing arms:1.331),(extra legs:1.331),(fused fingers:1.61051),(too many dingers:1.61051),(unclear eyes:1.331),lowers,bad hands,missing fingers,extra digit,bad hands,missing fingers,(((extra arms and legs)))
