AI for Images: From Midjourney to Firefly – The Complete Guide for Image Professionals

You've spent hours searching for the perfect stock photo on Shutterstock, or paid a photographer for a shot you never used. Or maybe you're a designer who needs to produce 50 product variants for an e-commerce site, and there's never enough time. The problem is always the same: quality images cost time and money. At Meteora Web, we've been working with AI image generation before it became mainstream — because when you manage dozens of e-commerce sites and landing pages, production speed is a direct cost. In this guide, we'll take you through the major AI image tools: Midjourney, DALL-E 3, Stable Diffusion, Adobe Firefly. We'll show you how to use them, when they make sense, and most importantly, how not to waste money and time on mediocre results. Because a poorly generated image is worth nothing; a well-generated one can sell a product.

Midjourney: The King of Aesthetic Quality

Midjourney remains the go-to tool for those seeking images with superior artistic quality. It works via Discord, which is both a limitation (no native web UI) and an advantage: prompt engineering has become a precise language. We use it to create product images, artistic concepts, and visuals for social campaigns. The secret? Don't write "a cat"; specify: lighting, angle, lens, mood, color palette, texture.

Prompt Engineering in Midjourney

The prompt is everything. An effective prompt has at least four elements: subject, context, style, technical parameters. Example: “product shot of a ceramic vase on a wooden table, natural lighting, depth of field, minimalist interior, 8k, –ar 4:3 –v 6.1”. Parameters like –ar (aspect ratio), –v (model version), –s (stylize), and –iw (image weight) make the difference between a flat result and a professional one.

When Midjourney Fails

Midjourney is terrible at text and logos: it generates gibberish letters. For that you need something else. Also, it has no official API (only via Discord Bot). If you need to integrate image generation into an automated workflow, go with Stable Diffusion or DALL-E via API.

DALL-E 3: Integration with ChatGPT Makes the Difference

DALL-E 3, integrated in ChatGPT Plus and via API, has a key strength: it understands natural language. You can describe a complex scene and it follows instructions closely, though sometimes it loses coherence with very specific details. We use it for quick drafts and social images because it's very fast. However, artistic quality is lower than Midjourney, especially in textures and lighting.

Practical Limitations

DALL-E 3 offers no fine control over parameters like aspect ratio or style. If you need precise images for a catalog, switch to Midjourney or Stable Diffusion. But for content marketing and visual brainstorming, it's a great ally.

Stable Diffusion: Total Control (If You Have a Decent PC)

Stable Diffusion is the workhorse for those who want maximum control. With ComfyUI or Automatic1111 you can generate images locally, with no prompt limits, using custom models (checkpoints, LoRA, ControlNet). We chose it for projects requiring consistency — for example, generating 50 product variants with the same background and lighting, changing only color or orientation.

Local Installation with ComfyUI

ComfyUI is a powerful but complex node-based interface. To start on Windows, you need Python 3.10 and an NVIDIA GPU with at least 6GB VRAM. Basic setup: download the ComfyUI repository, install dependencies, launch with python main.py. Then load a checkpoint (e.g., Realistic Vision) and start building the flow. Here's a minimal flow example for generating an image:

# Pseudocode for ComfyUI flow
# 1. Load checkpoint
# 2. Empty Latent Image (width, height, batch size)
# 3. CLIP Text Encode (positive and negative prompt)
# 4. KSampler (steps, cfg, sampler, scheduler)
# 5. VAEDecode
# 6. Save Image

We've automated flows with Python scripts to generate image batches for e-commerce. The only cost? Electricity and processing time.

ControlNet: Geometric Control

With ControlNet you can guide generation using a depth map, silhouette, or sketch. Useful when you need to maintain a model's pose or the composition of a scene. It's the difference between random images and production-ready ones.

Adobe Firefly: Generative AI in the Creative Suite

Firefly is Adobe's entry into generative AI, integrated into Photoshop, Illustrator, and Express. Its advantage is safe licensing: generated images are intended for commercial use without copyright risk (Adobe compensates creators for training data). We use it for inpainting and outpainting — modifying parts of existing images, or extending backgrounds beyond the edges.

Firefly vs. Generation from Scratch

For creating images from scratch, Firefly still lags behind Midjourney in quality. But for retouching and variations on existing images, it's unbeatable because it integrates directly into the Photoshop workflow. If you're a designer already using Adobe, Firefly is a natural extension.

AI Image Prompts: Universal Techniques

Result quality is 80% dependent on the prompt. Here are the rules we use in production:

• Specify photographic style: “product photography, studio lighting, white background, sharp focus” for e-commerce; “cinematic lighting, 35mm lens, shallow depth of field” for storytelling.
• Use negative words: “no text, no watermark, no blur” to avoid artifacts.
• Indicate composition: “close-up, overhead shot, wide angle”.
• Be specific about materials: “matte ceramic, brushed metal, translucent glass”.
• Use artistic references: “in the style of Annie Leibovitz, minimalist Scandinavian, retro 80s neon”.

A tip: write a long prompt first, then reduce it to the essentials. Fewer confusing words, better model understanding.

AI for Logo and Brand Identity: Limits and Opportunities

Many clients ask: “Can we generate the logo with AI?” The answer is: yes, but with caution. AI generators (Midjourney, DALL-E) don't understand fonts or create vectors. They give you a raster image, not a scalable logo. We use them for concepts and moodboards, but the actual logo is done by a designer in Illustrator. If you want to save, generate a base and then vectorize it with tools like Vectorizer.ai, but you lose precision. Our advice: use AI to explore creative directions, not for the final result.

Inpainting and Outpainting: Modifying Existing Images

Often you don't need to generate from scratch, but modify an existing image. Inpainting (removing or replacing an object) and outpainting (extending the background) are available in all tools. In Stable Diffusion with the Inpaint extension, you can select an area and regenerate it while maintaining context. In Photoshop with Firefly it's even simpler: select, type “remove the cup”, and it's gone. For e-commerce, inpainting is useful for removing imperfections from product photos without reshooting.

AI for E-commerce: Product Shots and Background Removal

AI has changed how we handle catalog images. At Meteora Web, we worked with a furniture client: they used to shoot every product in studio (€200 per shot). Now they generate images with Midjourney or Stable Diffusion, then use rembg (AI background removal) to flatten white backgrounds. The savings? Over 80% on production costs. Techniques:

• Generate product on a neutral background, then replace the background with AI (Adobe Firefly or remove.bg).
• Create color variants with different prompts on the same subject.
• Generate lifestyle shots (product in environment) without setting up a studio.

Warning: AI doesn't understand object physics — it sometimes generates inconsistent shadows. Better to use real images for the main product and AI for variants.

Copyright and AI-Generated Images: What You Need to Know

The legal landscape is evolving. In the US, images generated entirely by AI are not copyrightable (the Copyright Office has denied registration). In Europe, the situation is fluid: a “significant human contribution” is required for protection. We always recommend:

• Keep records of prompts and the creative process (to demonstrate human intervention).
• Use tools with clear commercial licenses (Adobe Firefly, Shutterstock AI).
• Do not use AI images for logos or registered trademarks without verifying protection.
• Read terms of service: some tools (Midjourney free tier) grant limited licenses.

Tool Comparison: Midjourney vs Firefly vs DALL-E

There's no single best tool. Each has its strength:

Tool	Image Quality	Control	Speed	Commercial License
Midjourney	Excellent (art, texture)	Medium (parameters)	Medium (queue)	Careful (read ToS)
DALL-E 3	Good	Low (prompt only)	High	Good (OpenAI enterprise)
Stable Diffusion	Variable (depends on model)	Maximum (local, ControlNet)	Low (local)	Open (but careful with checkpoints)
Adobe Firefly	Good (retouching)	High (inpainting)	High (cloud)	Excellent (indemnification)

At Meteora Web, we have a rule: for final product images → Midjourney or Stable Diffusion; for drafts and social → DALL-E; for retouching → Firefly. Never one tool for everything.

In Summary – What to Do Now

If you're a business owner or designer wanting to start today:

1. Choose a tool based on your need: if you want artistic images, start with Midjourney. If you need technical control, install Stable Diffusion. If you want simplicity, use DALL-E 3 via ChatGPT.
2. Learn effective prompt writing: take an image you like and try to replicate it with words. Use Prompt Hero for inspiration.
3. Check licensing: before using an image in a commercial catalog, verify the tool's terms. Adobe Firefly gives more peace of mind.
4. Don't skip post-processing: the AI image often needs a touch-up in Photoshop (lights, shadows, artifact removal). Don't ignore it.
5. Measure costs: calculate what you currently spend on images (stock, photographers, time) and compare it with the cost of AI subscriptions. We do this for every client — the numbers often speak for themselves.
