Stable Diffusion prompting cheatsheet

Last updated October 14th, 14:25   |   Expanded list

View examples I created with these prompt hacks Painting of a woman working at a table, holding a pen in one hand. She is gleefully looking at the viewer. Wearing a fancy blouse. Generated with Stable Diffusion/Waifu Diffusion. Painting of a girl sitting at a table with books on top, resting her head on her hand while daydreaming and smiling. Generated with Stable Diffusion/Waifu Diffusion. Painting of a girl with Mexican Catrina makeup, skull-like makeup. Generated with Stable Diffusion/Waifu Diffusion and a custom Textual Inversion embedding.

The further to the beginning of the prompt a word is placed, the greater its effect. Use multiple exclamation marks !! to stress a word and brackets () to reduce its strength. The latter does not work with all implementations. In the Automatic1111 webui () will stress a word instead.

3D renders & realism

Will improve the image: unreal engine, octane render, bokeh, vray, houdini render, quixel megascans, arnold render, 8k uhd, raytracing, cgi, lumen reflections, cgsociety, ultra realistic, 100mm, film photography, dslr, cinema4d, studio quality, film grain

Will achieve specific style: analog photo, polaroid, macro photography, overglaze, volumetric fog, depth of field (or dof), silhouette, motion lines, motion blur, fisheye, ultra-wide angle

Try experimenting with the names of professional cameras (e. g. Fujifilm XT3 or Canon Eos 5D) and lens specifications (e. g. 80mm Sigma f/1.4 or any ZEISS lens).

2d art

Will improve the image: digital art, digital painting, trending on artstation, golden ratio, evocative, award winning, shiny, smooth, surreal, divine, celestial, elegant, oil painting (helps improve multiple styles), soft, fascinating, fine art, official art, keyvisual

Will achieve specific style: color page, halftone, character design, concept art, symmetry, pixiv fanbox (for anime/manga), trending on dribbble (for vector graphics), precise lineart, tarot card

Note that Stable Diffusion's output quality is more dependant on artists' names than those of DALL-E and Midjourney. Without atleast one artist name the output might look like a beginner's work. Finetuned models like Waifu Diffusion and NovelAI can work without artist names.
For Waifu Diffusion and NovelAI, use Danbooru tags for the best results because they are both trained on a Danbooru scrape.

Negative prompts (derived from here, u/booktail & u/AcademicInside)

This requires an implementation that supports negative prompts, such as the Automatic1111 webui. It will prevent some common artifacts and result in better human portraits.
lowres, text, error, cropped, worst quality, low quality, jpeg artifacts, ugly, duplicate, morbid, mutilated, out of frame, extra fingers, mutated hands, poorly drawn hands, poorly drawn face, mutation, deformed, blurry, dehydrated, bad anatomy, bad proportions, extra limbs, cloned face, disfigured, gross proportions, malformed limbs, missing arms, missing legs, extra arms, extra legs, fused fingers, too many fingers, long neck
