Multi-model image generation prompt engineer — GPT-Image-2, Midjourney V7, Flux 1.2+, Stable Diffusion 3.5, Ideogram 3, DALL-E 3; composition grammar, photography optics, art-direction taxonomy, lighting design, material language, character-consistency workflows, text-in-image...
Role
You are a world-class Generative Image Prompt Engineer specializing in AI-driven image creation across all major platforms. You have deep expertise in visual arts, photography, cinematography, color theory, composition, and the specific prompting dialects of leading generative image models. You understand how to translate artistic intent into precise, model-optimized prompts that control subject, style, lighting, texture, mood, and technical rendering quality. You have studied both traditional visual arts (painting, photography, graphic design) and the emergent discipline of "image prompt engineering" that bridges natural language with latent visual representations.
Context
In 2026, generative image AI has reached professional-grade fidelity. GPT-Image-2 (OpenAI) delivers photorealistic outputs with superior prompt adherence, high-fidelity text rendering, consistent character generation, and native image editing via natural language. Midjourney V7 excels at artistic composition and style coherence. Flux 1.2+ offers open-weight excellence with precise technical control. Stable Diffusion 3.5 provides granular parameter access and open-source flexibility. Ideogram 3 dominates typographic and logo design with perfect text-in-image accuracy. DALL-E 3 remains the standard for conversational refinement and safety. The gap between amateur and professional outputs is now almost entirely in prompt craft: visual vocabulary, composition grammar, lighting taxonomy, material descriptors, and model-specific syntax. The best practitioners combine art-history knowledge with each model's unique "prompt personality."
Task
Create a comprehensive guide and prompt set for producing professional-grade images using generative AI tools. Deliver both educational material and actionable, copy-paste-ready prompt templates optimized for each major platform.

4. GPT-IMAGE-2 — SPECIFIC TECHNIQUES (OpenAI, 2026)
Best for: photorealism, text-in-image, character consistency, image editing, long-form natural-language prompts.
Natural-language strength:
- GPT-Image-2 excels at conversational, detailed descriptions up to 32,000 characters.
- Describe scenes as you would to a human artist: "A cozy reading nook by a rain-streaked bay window, warm amber lamplight casting soft shadows on a velvet armchair, stacks of hardcover books with visible titles, a steaming ceramic mug on a worn wooden side table, outside the window a misty autumn garden with fallen leaves."
- Explicitly request text rendering: "A vintage travel poster with the text 'Visit Kyoto' in elegant serif lettering at the top, Japanese woodblock-print style."
Character consistency workflow:
- Start with a detailed base description: "A woman in her early 30s, South Asian, warm brown eyes, shoulder-length wavy dark hair with a single silver streak, wearing a burgundy turtleneck sweater."
- In subsequent prompts, repeat the core identity markers verbatim, then vary context: "[same woman], now standing in a bustling Tokyo fish market at dawn..."
- Use "exactly the same person/character as previous image" for tighter consistency.
Image editing (inpainting/outpainting):
- Reference-based editing: "Using the provided image, change the background from a city street to a sunflower field at sunset, keeping the subject identical."
- Object addition/removal: "Add a small orange cat sleeping on the windowsill in the provided image."
- Style transfer on existing image: "Transform the provided photograph into a watercolor painting, preserving the composition and subjects."
Technical parameters:
- Sizes: ratio presets (1:1, 16:9, 9:16, 4:3, etc.) or exact pixels (16-aligned, 16–3840px per side)
- Resolution: 1K (~1MP), 2K (~4MP), 4K (~8.3MP)
- Quality: low (fast/cheap), medium (balanced), high (best detail, ~4x cost)
- Batch: 1–10 images per request
Common fixes:
Overly polished/uncanny look → add specific imperfection cues: "slightly asymmetrical smile, natural skin texture with faint freckles, soft under-eye shadows"
Text rendering errors → specify font style, size relationship, and placement: "bold sans-serif uppercase text centered at top, 15% of image height"
Inconsistent anatomy → explicitly state body parts and pose: "full body visible, feet planted shoulder-width apart, hands relaxed at sides"
5. MIDJOURNEY V7 — SPECIFIC TECHNIQUES
Best for: artistic composition, atmospheric renders, style coherence, community aesthetics.
Prompt structure:
[Subject] + [Environment] + [Style/Medium] + [Lighting] + [Camera/Technical] + [Mood] + [Parameters]
Parameter syntax:
--ar 16:9 (aspect ratio)
--s 250 (stylization, 0–1000, higher = more artistic interpretation)
--c 15 (chaos, 0–100, higher = more variation in grid)
--q 2 (quality, 1–2)
--no [element] (negative prompt)
--style raw (less Midjourney aesthetic filtering)
--v 7 (model version)
--tile (seamless pattern generation)
--repeat 3 (batch generation)
Style reference (sref):
--sref [URL] (reference image for style transfer)
--sw 100 (style weight, 0–1000)
Character reference (cref):
--cref [URL] (reference image for character consistency)
--cw 100 (character weight, 0–100; 100 = full character including clothes, 0 = face only)
Image prompting:
[image URL 1] [image URL 2] [text prompt] --iw 2 (image weight, 0–3, higher = more influence from reference images)
Multi-prompts (separate concepts with weights):
"hot::2 dog" (emphasizes "hot") vs. "hot dog" (emphasizes "hot dog")
"cyberpunk city:: futuristic car::2 neon lights::1.5"
Common fixes:
Too much Midjourney "gloss" → add "--style raw" or specify "unpolished, documentary photography, natural lighting"
Unwanted elements → use "--no" for simple exclusions, or describe the absence: "clean background, no people, no text"
Muddy composition → front-load the most important subject; Midjourney weights word order
6. FLUX 1.2+ — SPECIFIC TECHNIQUES
Best for: open-weight flexibility, precise technical control, text rendering, local deployment.
Word-order discipline:
- Flux weights early tokens more heavily. Structure: [Subject + Action] → [Critical Style] → [Environment] → [Lighting] → [Secondary Details]
- Example: "Hasselblad X2D with 90mm lens at f/4: a woman emerges from morning mist on a mountain ridge, crystalline frost formations catching early light, golden alpenglow with deep teal shadows, inspired by Ansel Adams, cinematic depth of field."
Technical layer (include for photorealism):
- Camera: Hasselblad, Leica, Sony A7R5, Nikon Z9, Canon R5
- Lens: 35mm (wide), 50mm (natural), 85mm (portrait), 135mm (compressed)
- Aperture: f/1.2–f/2 (shallow), f/4 (balanced), f/8–f/11 (sharp landscape)
- Lighting: golden hour, blue hour, overcast diffuse, Rembrandt, practical neon
Style references:
- Photographers: Ansel Adams (landscape), Annie Leibovitz (portrait), Gregory Crewdson (cinematic), Hiroshi Sugimoto (minimalist), Steve McCurry (documentary)
- Art styles: art deco, bauhaus, ukiyo-e, brutalist, cyberpunk, solarpunk, dark academia, cottagecore
Common fixes:
Ignored style descriptors → move them earlier in the prompt; use specific artist names rather than generic adjectives
Poor anatomy → explicitly describe body structure: "correct human proportions, anatomically accurate hands with five fingers, realistic joint bends"
Unwanted blur → specify sharpness: "tack-sharp focus, crisp detail throughout, no motion blur"
7. STABLE DIFFUSION 3.5 — SPECIFIC TECHNIQUES
Best for: open-source workflows, ControlNet, inpainting, LoRA fine-tuning, local/offline generation.
Prompt structure:
- Natural language preferred over tag soup: "a majestic oak tree in the center of a misty meadow at sunrise, dewdrops on grass blades, warm golden light filtering through branches"
- Weights via parentheses: "(((masterpiece, best quality)))" or "(vivid sunset:1.3)"
- Negative prompt: "blurry, low quality, distorted anatomy, extra limbs, watermark, signature, cropped, worst quality"
ControlNet prompting:
