ERNIE-Image's text rendering and composition capabilities are well-known. But in the realm of photographic realism, it also delivers impressive results — especially when you know how to speak its "photography language."

From Reddit discussions to professional AI photography workflows, users have discovered that ERNIE-Image has an excellent understanding of camera parameters, lens vocabulary, and lighting descriptions. Master these "photography passwords," and you can generate portrait and photography work from this 8B model that rivals professional cameras.

This guide covers everything from basics to advanced techniques for achieving photorealistic results with ERNIE-Image.

1. Where Does ERNIE-Image's "Photography DNA" Come From?

Unlike many models that pursue "perfect aesthetics," ERNIE-Image's training data underwent special processing:

High Real-Photo Ratio: The training dataset includes a large proportion of real photographs rather than just AI-generated images.
Metadata Understanding: Through VLM re-captioning, the model learned the actual visual meaning of terms like "85mm lens," "f/1.8 aperture," and "1/125s shutter."
Aesthetic Calibration: The ERNIE-Image-Aes model weights authentic photography styles higher in its aesthetic scoring — meaning realism itself is a model optimization direction.

So when you include photography terms in your prompt, it's not just "decorating" the prompt — the model genuinely understands what these terms correspond to visually.

2. Core Elements of Photography Prompts

To achieve photorealistic results, prompts should include the following elements:

2.1 Lens Vocabulary

Lens/Focal Length	Effect	Best For
`35mm`	Human perspective, natural perspective	Street photography, environmental portraits
`50mm`	Standard view, close to human eye	Half-body portraits, documentary
`85mm`	Classic portrait length, soft bokeh	Close-ups, portraits
`135mm`	Telephoto compression, extreme blur	Facial close-ups
`24mm`	Wide-angle, exaggerated perspective	Environment, architecture
`macro`	Extreme close focus	Details, products

2.2 Lighting Description

Lighting Type	Keywords	Visual Effect
Natural light	`natural window light`, `soft diffused daylight`	Soft, authentic
Golden hour	`golden hour`, `warm sunset light`	Warm, dramatic
Softbox	`soft studio lighting`, `softbox`	Professional, shadowless
Rembrandt	`Rembrandt lighting`	Classic portrait
Backlight	`backlight`, `rim light`	Silhouette, atmospheric
Flash	`on-camera flash`, `direct flash`	Vintage, documentary

2.3 Stylistic Descriptions

Style	Keywords	Effect
Film look	`35mm film`, `Kodak Portra 400`, `Fujifilm`	Warm, grainy
Documentary	`documentary style`, `photojournalism`	Authentic, unretouched
Editorial	`editorial photography`, `fashion editorial`	Polished, dramatic
Candid	`candid`, `unposed`, `street photography`	Natural, storytelling

3. Five Photography Scene Templates

Scene 1: Natural Light Environmental Portrait

Principle: Use window natural light with appropriate focal length and exposure to simulate a real photographer's lighting setup.

Prompt Template:

Natural light portrait of a [subject description], sitting by a large window, soft diffused daylight, [angle of light], [background treatment], [camera/lens], [film style], [quality]

Example:

Natural light portrait of a woman in her late 20s with wavy brown hair, sitting by a large window, soft diffused daylight coming from the side, slight background blur, 85mm lens at f/1.8, shot on Kodak Portra 400 film, candid expression, skin texture visible, warm film tones

💡 Community Tip: Reddit users report that adding skin texture visible or natural skin texture significantly reduces the common "plastic look" issue with ERNIE-Image-Turbo.

Scene 2: Golden Hour Outdoor Portrait

Principle: Simulate the golden sunlight 1-2 hours before sunset — one of the most popular lighting conditions in photography.

Prompt Template:

Portrait of a [subject] at golden hour, [location], warm sunset light from the [direction], [atmosphere], [camera setting], [style]

Example:

Portrait of a young man with short dark hair standing in a wheat field at golden hour, warm sunset light from behind creating rim light on his shoulders, golden tones, slight lens flare, 50mm lens, shallow depth of field, cinematic photography, film grain, nostalgic mood

Scene 3: Urban Street Photography

Principle: Simulate the visual language of a documentary photographer capturing moments in an urban setting.

Prompt Template:

Street photography of a [subject] in [urban setting], [weather/light], [composition detail], [camera spec], [film aesthetic]

Example:

Street photography of an elderly man crossing a rain-wet Shibuya crossing at dusk, neon signs reflecting on wet pavement, umbrella in hand, motion blur from passing traffic, 35mm lens, high contrast black and white, grainy film texture, documentary style, candid moment

Scene 4: Studio Fashion Portrait

Principle: Simulate professional studio lighting setups with precise quality control.

Prompt Template:

Editorial fashion portrait of [subject], [wardrobe description], [lighting rig], [background], [camera spec], [post-processing]

Example:

Editorial fashion portrait of a woman in a red silk dress against a dark gray seamless backdrop, dramatic Rembrandt lighting from a large softbox above-left, sharp catchlights in eyes, 85mm lens at f/2.8, medium format camera, high-end fashion editorial style, flawless skin with natural texture, Vogue aesthetic

Scene 5: Product & Still Life Photography

Principle: Use photographic language to describe product placement, light direction, and material质感.

Prompt Template:

[Product description] on [surface], [lighting direction], [camera spec], [depth of field], [commercial style], [quality]

Example:

A matte black wireless mechanical keyboard on a dark wood desk, soft studio lighting from above-left creating gentle shadows, macro lens, shallow depth of field focused on the keycaps, subtle RGB backlight glow, commercial product photography, sharp details, 8K, clean minimalist composition

4. Eliminating the "AI Look": Practical Techniques

Technique 1: Add "Imperfection" Keywords

The "plastic look" common in AI-generated images often comes from overly perfect surfaces. Add these descriptions for more realism:

natural skin texture, visible pores, slight imperfections, realistic skin, natural wrinkles, freckles, subtle blemishes, not airbrushed

Technique 2: Specify Real Camera and Film Models

ERNIE-Image has good understanding of specific camera and film brands:

shot on Fujifilm X-T5 with 35mm f/2 lens
shot on Canon EOS R5 with 85mm f/1.2
Kodak Portra 400, Fuji Pro 400H, Ilford HP5 Plus 400

Technique 3: Use Flash Descriptions

direct on-camera flash, harsh shadows, slightly overexposed skin, vintage flash photography style

This technique comes from the community — point-and-shoot film camera, front flash effectively eliminates the "plastic look" of the Turbo variant.

Technique 4: Temperature and Atmosphere

Pure color descriptions often produce flat results. Add temperature or atmosphere words:

Before	After
`blue lighting`	`cool blue hour light, slightly underexposed, moody`
`warm lighting`	`warm golden hour sun, low contrast, hazy`
`dark`	`dimly lit, deep shadows, noir atmosphere`

Technique 5: Disable Prompt Enhancer

For photography-realism prompts, disabling Prompt Enhancer is recommended because:

Photography prompts are already quite detailed
PE may add non-photographic modifiers ("vibrant," "stunning")
Disabling PE keeps output closer to pure photographic language

5. Photography Workflow: From Concept to Final Output

5.1 Rapid Iteration Mode

Use ERNIE-Image-Turbo (8 steps, ~0.5 CU/image) for rapid iteration:

Steps:

Start from a basic portrait template
Adjust light direction (side light vs backlight)
Change focal length (35mm vs 85mm vs 135mm)
Try different film styles
Record the best seed value

5.2 Final Output Mode

Once satisfied with the composition, switch to Standard ERNIE-Image (50 steps, ~3-4 CU/image):

Use the seed obtained from Turbo iteration
Keep the prompt unchanged
Standard mode delivers more detail, more accurate lighting
Suitable for print output or commercial use

5.3 Recommended Complete Workflow

[Concept] → Turbo iteration (composition, lighting, focal length) → Record optimal seed
         → Standard final generation (using fixed seed)
         → Upscaling (optional) → Post-processing

6. Troubleshooting

Issue: Face Looks Like "Plastic" (Overly Smooth)

Cause: Turbo mode lacks detail at 8 steps, or PE adds excessive aesthetic modifiers.

Solutions:

Switch to Standard mode (50 steps)
Disable Prompt Enhancer
Add natural skin texture, visible pores, realistic skin details, matte finish
Use flash description: on-camera direct flash, unretouched

Issue: Background Too Blurry or Lacks Detail

Cause: Depth of field is too shallow in portrait mode.

Solutions:

Specify f/5.6 or f/8 instead of maximum aperture
Use deep depth of field or everything in focus
Add more background detail

Issue: Skin Tone Inaccuracies or Unnatural Color

Cause: ERNIE-Image's skin tone rendering may vary with insufficient lighting descriptions.

Solutions:

Add color temperature: neutral white balance, accurate skin tones
Specify skin type: fair skin with freckles, warm olive skin tone, deep dark skin with natural highlights
Disable PE: complex portrait descriptions may be rewritten by the Enhancer

7. Summary

ERNIE-Image's photorealistic capabilities exceed most users' expectations — the key is using the right "photography language."

Core Element	Best Practice
Lens focal length	85mm for portraits, 35mm for street, 135mm for close-ups
Lighting type	Natural window light is most reliable, golden hour has highest success rate
Film style	Kodak Portra 400 (warm tones), Fuji Pro 400H, Ilford HP5 (B&W)
Eliminate AI look	`natural skin texture` + flash description
PE strategy	Disable for detailed photography prompts
