AI painting is becoming a new way of creative expression. Whether you have studied art or not, as long as you master the technique of writing prompt words, you can generate stunning visual works with words. This article will take you from scratch to understand the basic process and practical skills of AI painting.
##What is AI painting?
AI painting refers to the technology of using deep learning models to automatically generate images based on text descriptions (prompt words). The current mainstream AI painting tools include Stable Diffusion, Midjourney, and DALL · E. These models, trained on massive images, are able to understand the correspondence between text and visual elements, transforming abstract descriptions into concrete images.
##The basic structure of prompt words
A good prompt usually includes the following elements:
Main description: Clearly define what you want to draw. For example, 'a white cat sitting on the windowsill' is more accurate than 'a cat'.
Style specification: Specify the visual style you want, such as watercolor, cyberpunk, Studio Ghibli style, photographic realism, etc. Different styles will significantly affect the final effect.
Environment and lighting: Describe the background and lighting conditions, such as "the seaside under the sunset", "the dim library", etc. These details make the picture more atmospheric.
Quality keywords: Adding words such as 8K, rich details, and high resolution can improve the precision of the image.
##Practical skills
Firstly, make good use of negative prompts. Telling AI what you don't want, such as "blurry, deformed, extra hands," can effectively avoid common problems.
Secondly, iterate gradually from simple to complex. First, use brief prompts to generate a rough composition, and then gradually add details, instead of writing everything at once.
Thirdly, try different models and parameters. Stable Diffusion is suitable for highly customized local generation, Midjourney excels in artistic style, and DALL · E has advantages in understanding complex semantics.
##Advanced direction
After mastering the basic prompt words, you can try advanced techniques such as ControlNet to control composition, LoRA to fine tune specific styles, and photo editing. The possibility of AI painting is far beyond just inputting text, it is redefining the threshold and boundaries of creation.
