Summary of “9 이미지 생성 AI 기초 2”

This video provides a detailed tutorial and analysis on AI image generation, focusing on prompt writing, style and atmosphere selection, tool usage, and iterative improvement strategies. It also introduces practical exercises and compares popular AI image generation platforms.

Key Technological Concepts and Product Features

1. Prompt Writing for AI Image Generation

A good prompt consists of three key elements:

Subject Description: Specifies the main object/character, environment, actions, and details (e.g., breed, color, era). More specific prompts reduce ambiguity and improve output accuracy.
Style: Defines how the image is expressed — realistic (photorealistic, 4K/8K), painterly (oil, watercolor, impressionism), or digital art (3D rendering, pixel art). Style affects the emotional impact and use case of the image.
Atmosphere: Sets the mood via lighting, color palette, time of day, weather, and emotional tone (e.g., warm golden hour, mysterious night, cool pastel tones). This helps convey the intended story or feeling.

2. Iterative Prompt Improvement

Start with a basic prompt and gradually add details to improve specificity, style, and atmosphere.
Evaluate outputs for accuracy, detail quality, composition, and consistency.
Address common issues like missing subjects, style mismatches, or mood discrepancies by refining prompts incrementally.
Multiple attempts (3-5 times) are often needed to reach the desired result.

3. AI Image Generation Tools Reviewed

Bing Image Creator (Microsoft)

Free, browser-based, no separate software needed.
Supports Korean and English prompts with natural language understanding.
Uses DALL·E 3 technology for fast, high-quality image generation (10-30 seconds).
Generates multiple candidate images per prompt; easy to download and share.
Best suited for pure image creation and quick prototyping.
Limited post-editing features; often requires external tools for further editing or layout.

Canva AI (referred to as Camba in transcript)

Integrated design platform with AI image generation and editing tools.
Allows seamless combination of AI-generated images into presentations, posters, and social media content.
Provides editing features: background removal, resizing, color adjustments, filters, text insertion.
Offers thousands of templates for professional design projects.
Free tier has limited generation capacity; advanced features require paid plans.
Ideal for design workflows, marketing, and educational materials.

4. Practical Exercises and Use Cases

Creating images with prompts like “golden retriever running in a sunny park” to test accuracy and atmosphere.
Imaginative topics like “future campus” with digital art style and hopeful atmosphere to encourage creativity.
Emphasis on using five senses and detailed descriptions to enrich prompts.
Encouragement to document prompt iterations, image results, and reflections as part of assignments.

5. Quality Evaluation Criteria

Accuracy: Faithfulness to prompt content and visual consistency.
Detail Quality: Clean lines, correct anatomy (e.g., fingers), and no distortions.
Composition: Balanced, stable layout without awkward empty spaces or cut-offs.
Common AI image issues include unnatural hands/faces, distorted perspectives, and text errors.

6. Additional Tools and Workflow Tips

Use background removal tools like Remove.bg for post-processing.
Upscaling tools can enhance resolution and image quality.
Organize and save generated images with clear file naming and folder structure for easy retrieval and reuse.
AI-generated images can be assets for presentations, blogs, social media, or portfolios.

7. Future Topics and Ethical Considerations

Upcoming lessons will cover advanced techniques like inpainting (image editing/modification).
Discussion on maintaining style consistency and advanced prompt engineering.
Ethical considerations in AI-generated photography and image use.
