AI Image Prompt Optimizer

This workflow takes user-submitted image generation prompts and refines them using AI best practices, ensuring prompts are detailed, descriptive, and optimized for producing high-quality, visually compelling images with AI image generators.

How the AI Flow works - AI Image Prompt Optimizer

How the AI Flow works

Receive User Prompt

Accepts a prompt from the user for an image to be generated.

Apply Best Practices Template

Rewrites the user's prompt using a template that incorporates AI image generation best practices, ensuring clarity and detail.

Enhance with AI Agent

Utilizes an AI agent to further refine and optimize the prompt, making it natural, descriptive, and complete.

Display Enhanced Prompt

Presents the improved prompt back to the user, ready for use with AI image generation tools.

Prompts used in this flow

Below is a complete list of all prompts used in this flow to achieve its functionality. Prompts are the instructions given to the AI model to generate responses or perform actions. They guide the AI in understanding user intent and generating relevant outputs.

Prompt

Creates an LLM prompt template for rewriting user image generation prompts based on best practices, including subject, description, and style.

                --- AI IMAGE GENERATION BEST PRACTICES---
Elements of a the prompt:
1. Subject
2. Description
3. Style/Aesthetic

Subject: Who and What

Start your prompt with the main subject, typically a noun. While a single subject can generate a general image, more descriptive prompts usually yield results closer to your vision.

    💡 Pro tip: Avoid using abstract concepts (love, hate, justice, infinity, joy) as subjects. Use concrete nouns (human, cup, dog, planet, headphones) as the subject of your prompt for more accurate results.


Description: What They Are Doing, Where, and How

Enhance your prompt with adjectives to add depth and complexity. Include details that answer:

    What is happening?
    What is the subject doing?
    How is the subject doing this?
    What's happening around the subject?

The background is crucial, so don't neglect it in your description.
The more detailed prompt resulted in a clearer, more complex and realistic image.

Another example demonstrates how additional descriptors can lead to a significantly more complex and detailed rendering.

for example:
- instead of "Raccoon reading" it can be "professional photo of a racoon reading a book in a library, close shot"
This generated image of a finch demonstrates how AI can render a generic, but very accurate image even without additional descriptors. However, the rendering on the right demonstrates how AI image generators, in this case can work with more elements to render a significantly more complex visual.

Aesthetic and Style: How It Looks

Complete your prompt with words that dictate the overall aesthetic and style:

    Medium: "photo", "oil painting", "fresco", "3D rendering"
    Art movements: impressionist, gothic, steampunk, etc.
    Artist influences: Include famous names to blend their styles
    Framing: "close up", "medium shot" to specify angle and distance

#2 Keep it natural and descriptive
Medium prompt (30-50 words):

Include additionally these elements:
    Subject: "A majestic Bengal tiger with vibrant orange fur and black stripes"
    Environment: "In a lush tropical rainforest with towering trees and dense undergrowth"
    Lighting: "Dappled sunlight filtering through the canopy, creating a play of light and shadow"
    Colors: "Rich greens of the foliage contrasting with the tiger's orange coat"
    Mood: "A sense of tension and anticipation as the tiger stalks its prey"
    Composition: "The tiger is positioned in the lower left third of the frame, its gaze directed towards the right"

Flow description

Purpose and benefits

PhotoAI Agent Workflow: Human-Readable Description

Overview

The PhotoAI Agent workflow is designed to help users automatically refine and enhance their image generation prompts for AI art tools. By leveraging best practices in prompt engineering, it ensures that user-submitted prompts are rewritten to be more descriptive, detailed, and visually informative. This results in prompts that guide AI image generators to create more accurate, complex, and visually compelling images.

How the Workflow Operates

The workflow consists of the following main components:

StepComponentRole in Workflow
1Chat InputReceives the user’s initial image prompt.
2Prompt TemplateApplies best practices and rewrites the prompt for clarity, detail, and style.
3AI AgentProcesses the refined prompt, ready for interaction or further handling.
4Chat OutputDisplays the final, upgraded prompt back to the user.

Step-by-Step Process

  1. User Submission (Chat Input)

    • The user submits a simple or unrefined prompt for an image they wish to generate (e.g., “cat playing piano”).
  2. Prompt Enhancement (Prompt Template)

    • The prompt is passed into a template that applies a set of best practices for AI image generation:
      • Subject: Ensures the subject is a concrete noun (not an abstract concept).
      • Description: Adds details about what is happening, where, how, and context (e.g., environment, actions, background).
      • Aesthetic/Style: Specifies medium (photo, painting, 3D), art style, artist influences, lighting, mood, composition, and other visual cues.
    • The template provides examples and guidance, automatically transforming user input into a richer prompt.
  3. Prompt Processing (AI Agent)

    • The enhanced prompt is processed by an AI agent node, which is capable of further interacting with tools or workflows if needed.
  4. Display Result (Chat Output)

    • The upgraded, detailed prompt is presented to the user, ready to be copied into an AI image generation tool.

Benefits and Use Cases

Why Is This Useful?

  • Consistency and Quality: Ensures every prompt follows proven best practices, improving the quality and realism of generated images.
  • Scalability: Automates the tedious process of rewriting or enhancing prompts, allowing users (from individuals to agencies) to scale content creation without manual effort.
  • User-Friendly: Helps users with little experience in prompt engineering achieve professional-grade results.
  • Creativity Booster: Guides users to think in more detail about their desired images, leading to more creative and precise outcomes.

Example Use Case

Input PromptEnhanced Output Prompt
“Raccoon reading”“Professional photo of a raccoon reading a book in a library, close shot, soft lighting, cozy atmosphere.”
“Tiger in forest”“A majestic Bengal tiger with vibrant orange fur and black stripes, in a lush tropical rainforest with dappled sunlight filtering through the canopy, rich greens of the foliage, a sense of tension as the tiger stalks its prey, positioned in the lower left third of the frame.”

The workflow transforms basic prompts into comprehensive instructions for AI, enabling the generation of images that are both specific and visually rich.

Summary

PhotoAI Agent streamlines and automates the process of crafting powerful prompts for AI image generators. By embedding best practices into an automated workflow, it saves time, reduces errors, and empowers users of all skill levels to create stunning AI-generated imagery at scale.
