🎬 Complete Tutorial: Creating Your First Professional AI Image
Let me walk you through the entire process of creating a professional-quality AI image, from prompt crafting to final output. I'll use Google ImageFX since it's completely free and produces excellent results.
Choose Your Tool & Access It
Head to Google ImageFX. No signup required – just visit the page and you're ready to start. Actually, that's one of the things I love about it.
Pro Tip: Bookmark the page since Google Labs URLs sometimes change. You can also access it through Google's main AI test kitchen.
Craft Your Prompt
Here's where most people mess up. A good prompt is specific but not overly complex. Let's create a professional headshot:
Notice how I included: subject description, clothing, setting, lighting, camera details, and style. This gives the AI enough context without being overwhelming.
Generate & Evaluate
Click generate and wait about 10-15 seconds. ImageFX will give you multiple variations. Here's what to look for:
- Facial features look natural and proportional
- Lighting is consistent throughout the image
- Background complements the subject
- Overall composition feels balanced
If none of the results are quite right, don't worry – that's normal. This is where iteration comes in.
Refine Your Prompt
Based on your first results, adjust your prompt. Maybe the lighting was too harsh, or the background too busy. Here's a refined version:
I added "minimalist" and "clean" to get a less cluttered background, and "soft window lighting" for better illumination.
Download & Post-Process
Once you're happy with the result, download the image. For professional use, you might want to do some light post-processing:
- Adjust brightness/contrast if needed
- Crop for better composition
- Apply subtle sharpening
- Save in the appropriate format (PNG for transparency, JPEG for web)

🤔 Frequently Asked Questions
Are free AI image generators really free?
Most are genuinely free with some limitations. Google ImageFX is completely free with unlimited generations. Bing Image Creator gives you 25 "boosts" per day for faster generation. Others like Canva and Adobe Firefly offer free tiers with monthly limits. The key is understanding what "free" means for each tool.
Can I use AI-generated images for commercial purposes?
Generally yes, but always check the specific terms of service. Most free tools like ImageFX, Bing Creator, and Canva allow commercial use. Adobe Firefly is specifically designed for commercial use since it's trained on licensed content. However, avoid generating images of copyrighted characters or trademarked content.
How do I write better prompts for AI image generators?
Start with the main subject, add descriptive details about appearance, setting, and mood. Include technical photography terms like "shallow depth of field" or "golden hour lighting." Be specific but not overly complex. For example: "Portrait of a professional chef in a modern kitchen, wearing white coat, warm lighting, shot with 85mm lens" works better than just "chef photo."
Which free AI image generator produces the best quality?
Based on my testing, Google ImageFX consistently produces the highest quality results, especially for photorealistic images. Bing Image Creator (powered by DALL-E 3) is also excellent. For artistic styles, Leonardo.AI offers great variety. The "best" depends on your specific needs – ImageFX for realism, Ideogram for text-heavy images, Canva for social media content.
Are there any restrictions on what I can generate?
Yes, all tools have content policies. You can't generate violent, sexual, or illegal content. Most block attempts to create images of real people without permission. Some are stricter than others – Adobe Firefly has the most restrictive policies, while tools like Leonardo.AI are more permissive for artistic content.
How can I generate images with text that's actually readable?
Ideogram is specifically designed for this and excels at text rendering. For other tools, keep text short and simple, use common fonts, and be very specific about text placement. For example: "Logo with the text 'COFFEE SHOP' in bold sans-serif font, centered, black text on white background." Sometimes it's easier to add text afterward using Canva or similar tools.
What's the maximum resolution I can get from free tools?
It varies by tool. Most free generators produce 1024x1024 pixel images, which is suitable for most web uses. Adobe Firefly can generate up to 2048x2048 pixels. Leonardo.AI goes up to 1536x1536. For higher resolutions, you'll need to use AI upscaling tools or upgrade to paid plans.
How do I maintain consistency across multiple AI-generated images?
Use consistent prompt structures and style descriptors. Create a "style guide" with specific phrases that work well. For characters, describe them the same way each time. Tools like Leonardo.AI and Canva allow you to save and reuse successful prompts. Consider using the same camera settings, lighting descriptions, and artistic style references across all generations.
What should I do if a tool stops working or reaches its limit?
Always have backup options. If Bing Creator reaches its daily limit, switch to ImageFX. If Leonardo.AI runs out of tokens, try Canva. Keep a list of 3-4 tools that work well for your use case. Some tools reset limits daily, others monthly. Plan your usage accordingly, and consider spreading your generations across multiple tools to avoid hitting limits.
