Image Prompt

Image Prompt

Section titled “Image Prompt”

The backend builds the final image prompt sent to the image provider by combining a style prefix, an instruction, and the scene’s image prompt.

Formula

Section titled “Formula”
[style prefix from style guide] + [image_instruction or DEFAULT_IMAGE_INSTRUCTION] + [scene image_prompt]

Style prefix

Section titled “Style prefix”

When the project or work has a style guide, the backend builds a style prefix in prompts/image.ts (buildImageStylePrefix). It typically includes:

  • Base: e.g. “Professional photography, natural lighting, lifelike textures”
  • Color palette (if set)
  • Tone and tempo (if set)

This prefix is prepended so all generated images match the project’s look.

Image instruction

Section titled “Image instruction”
  • Default: DEFAULT_IMAGE_INSTRUCTION from shared: “Realistic photography style. Photo of real-world scene, natural lighting and lifelike textures.”
  • Override: Project or work imageSystemPrompt, or the value sent in the generate request (image_instruction). If empty, the default is used.

Negative prompt

Section titled “Negative prompt”

The scene’s negative_prompt is sent as-is to the image provider (when supported) to exclude unwanted elements.
