- Better composition: balanced, aesthetically pleasing placement of elements in the image.
- A wide range of styles: the ability to reproduce various artistic techniques accurately.
Prompting recommendations for Stable Diffusion XL
Use detailed descriptions:
Provide detailed, layered descriptions to get the result you want.
Example:
Futuristic megacity on Mars, huge glass domes, flying vehicles, red desert in the background, holographic billboards, science fiction style, photorealistic quality.
Emphasize atmosphere and lighting:
Pay particular attention to describing the atmosphere and the lighting effects.
Example:
Mysterious forest at dawn, sunbeams breaking through the mist, soft diffused light, dewdrops on the leaves, magical atmosphere.
Combine realism and fantasy:
Experiment with mixing realistic elements and fantastical concepts.
Example:
Realistic underwater city in the Mariana Trench, bionic structures, glowing jellyfish as the light source, detailed marine flora and fauna.
Describe textures and materials precisely:
Pay attention to describing surfaces and materials to achieve the visual effect you want.
Example:
Dragon sculpture in polished bronze with a patina, scaly texture, reflective surfaces, play of light on the metal, detailed metalwork.
Use technical terms:
Apply specific photographic or artistic terms for tighter control over the result.
Example:
Portrait of an elderly sage, shot with Rembrandt lighting, deep shadows, warm color palette, bokeh in the background, 85mm focal length, soft focus.
Experiment with composition:
Describe the composition you want and how elements should be placed in the frame.
Example:
Majestic sunset over the Grand Canyon, panoramic view, golden hour, a lone tree in the foreground, a winding river below, dramatic clouds, rule of thirds in the composition.
