ComfyUI-Prompt-Camera-Assistant

This project is designed for:

• Prompt engineers
• Generative photography & cinematography
• ComfyUI power users
• Workflow-driven AI creators

Features

• 📷 Still vs Video mode selection
• 🎥 Cinema camera support (ARRI, RED, Blackmagic, Sony, Canon)
• 📸 Still camera support (DSLR, Mirrorless, Film)
• 🔍 Lens types & focal behavior
• 🎞 Iconic film stocks (negative, slide, instant, digital looks)
• ⚙️ Exposure controls (aperture, ISO, shutter speed)
• ✨ Stylistic modifiers
  • Bokeh styles
  • Focus styles
  • Motion blur presets
• 🧩 Built as a ComfyUI custom node
• 🛠 Backend-driven dropdowns (clean UI, dynamic expansion)

Why Camera & Lens Metadata in AI Prompts?

Modern diffusion and generative models respond strongly to photographic language:

• Camera systems influence realism and tone
• Lens types affect perspective and depth
• Film stocks guide color science and contrast
• Exposure terms shape lighting and motion

This node standardizes those inputs so users don’t need to memorize or manually type camera syntax.

Project Structure

PromptCameraAssistant/ ├── nodes.py ├── README.md

• nodes.py
  Contains:
  • PromptCameraLibrary – the backend camera/lens/film data
  • PromptCameraAssistant – the ComfyUI node definition

Installation

1. Navigate to your ComfyUI custom nodes directory: ComfyUI/custom_nodes/

2. Clone this repository into ComfyUI's custom_nodes directory:

git clone https://github.com/bcasadei/ComfyUI-Prompt-Camera-Assistant.git

3. Restart ComfyUI

The node will appear under: CATEGORY: Prompt / Camera
