Generating a high-quality whole body image using Stable Diffusion requires careful crafting of the prompt. The prompt needs to provide enough context and details for the AI to render a full-length portrait while avoiding common issues like awkward crops or distortions.
This article will provide prompt structure recommendations, important elements to include, and examples of effective whole body prompts. With the right approach, Stable Diffusion can produce stunning full-body portraits comparable to professional photography.
Prompt Structure
An effective whole body prompt generally follows this overall structure:
- Subject descriptor
- Full body qualifier
- Pose/action qualifier
- Camera framing
- Fine details
- Style/medium qualifiers
Here is a breakdown of each element:
Subject Descriptor
Clearly identify the main subject with adjectives and specifics. For example:
- A tall, slender woman
- An elderly farmer
- A fierce knight in armor
Full Body Qualifier
Use a descriptor that conveys the full body form such as “full-length portrait”, “head-to-toe”, “whole body”, or “full figure”.
Pose/Action Qualifier
Add a pose or action to give a sense of movement and prevent a rigid standing pose:
- Striding purposefully
- Leaning against a wall
- Examining a flower
Camera Framing
Specify the camera perspective to frame the entire body:
- Shot from thigh level
- Full body centered in frame
- Wide landscape format
Fine Details
Provide additional details about the subject’s attire, expression, and environment for added realism.
Style/Medium Qualifiers
Indicate desired artistic style and medium such as “oil painting”, “digitally painted”, “intricate digital illustration”, etc.
Elements to Include
In addition to the base prompt structure, include elements like the ones below for best results:
Aspect Ratio
The aspect ratio impacts the camera perspective and composition. A widescreen ratio like 16:9 or 21:9 works well for whole body framing.
Example: --ar 16:9
Number of Subjects
If generating an image with multiple subjects, specify the exact number to prevent awkward cropping.
Example: A group of three young women, whole body...
Background Details
Add some environment details so the background complements the main subject. This prevents a sparse or disconnected background.
Example: ...standing in a lush garden with stone walls and ivy
Lighting
Define a lighting style that flatters the entire body shape rather than just the face. Side lighting often works best.
Example: Dramatic side lighting accentuates her form
Proportions
Suggest realistic body proportions to avoid distortions.
Example: With natural proportions, perfectly balanced features
Example Prompts
