Achieving Photorealism with ERNIE-Image:告别 Plastic Look, Cinematic Film-Quality Portraits
TL;DR: ERNIE-Image excels at text rendering and structured layouts, but many users report a "plastic look" in portraits. This guide covers 10+ community-verified techniques to dramatically improve photorealism — from film camera prompts to skin texture details — helping you achieve Midjourney-quality realism with an open-source 8B model.
1. The "Plastic Look" Problem: ERNIE-Image's Weakness in Photorealism
Since its release, the community has universally praised ERNIE-Image for its text rendering (LongTextBench 0.9733) and structured layout capabilities. But in the realm of photorealism, Reddit users have been direct:
"ZIT is good at text and prompt adherence, but Flux Klein is still the best for realism."

What Is the "Plastic Look"?
The "Plastic Look" is a common issue in AI-generated portraits:
- Overly smooth skin — Missing pores, fine lines, and micro-textures
- Unnatural gloss — Skin reflection looks like plastic, not real skin oils
- Over-saturated colors — Lacking the natural tonal transitions of film photography
Why Does It Happen?
ERNIE-Image is built on a DiT (Diffusion Transformer) architecture. Its training data includes a significant amount of design-oriented images (posters, infographics), making the model excel at stylized images but requiring more precise prompt guidance for photorealistic outputs.
2. Core Technique: The Film Camera Prompt Formula
Reddit users, through extensive testing, discovered a set of prompt keywords that significantly reduce the plastic look:
Universal Film Formula
[Subject Description], point-and-shoot film camera, 35mm, front flash, candid shot, natural skin texture
Component Breakdown
| Prompt Component | Purpose | Effect |
|---|---|---|
point-and-shoot film camera |
Point-and-shoot aesthetic | Reduces over-rendering, adds natural grain |
35mm film camera |
35mm film style | Cinematic tones, soft light transitions |
front flash |
Direct front flash | Removes overly smooth lighting, adds realism |
onboard flash |
Built-in flash | Similar to front flash, more natural flash effect |
candid shot |
Candid feel | Removes "posed" AI look |
Flickr |
Retro film style | Simulates early internet photography roughness |
Polaroid |
Polaroid style | Soft colors + film border feel |
3. Portrait Photography: Skin Texture Realism Secrets
Skin Texture Prompt Keywords
detailed skin texture, visible pores, fine micro-details, subtle peach fuzz, natural skin oiliness
Practical Examples
Basic Prompt (Heavy Plastic Look):
A portrait of a young woman, beautiful face, studio lighting
Advanced Prompt (Strong Realism):
A portrait of a 25 year old woman, natural makeup, detailed skin texture with visible pores,
fine micro-details, natural skin oiliness, point-and-shoot film camera, 35mm,
front flash, candid shot, soft natural lighting
Key Technique: Add "Imperfection" Details
The core of realism is imperfection. These prompt elements significantly increase authenticity:
subtle skin imperfections— Minor skin flawsnatural asymmetry— Natural asymmetryslight shadow under eyes— Slight under-eye shadowswindblown hair— Windblown haireveryday photo— Everyday photo feel
4. Lighting Control: Natural Light and Flash Prompts
Natural Light Scenes
golden hour, warm natural light, soft window light, overcast day, dappled sunlight
Flash Scenes
direct flash, front flash, harsh flash lighting, disposable camera flash
Cinematic Lighting
cinematic lighting, soft key light, rim light, chiaroscuro, film noir lighting
Best Combination for Realism
A portrait of a woman standing by a window, soft natural window light,
detailed skin texture, point-and-shoot film camera, 35mm, candid moment
5. Turbo vs Base: Choosing for Photorealism
ERNIE-Image offers two versions with different photorealism performance:
| Dimension | ERNIE-Image (Base) | ERNIE-Image Turbo |
|---|---|---|
| Inference Steps | 50 steps | 8 steps |
| Photorealism Quality | ★★★★★ | ★★★★ |
| Generation Speed | Slower | ~6x faster |
| Plastic Look Severity | Lower | Slightly higher |
| Recommended Use | Final output | Rapid iteration |
Recommended Workflow
- Turbo for Rapid Iteration — Use Turbo mode to quickly test multiple prompt combinations
- Base for Final Output — Once you find the best prompt, use Base mode for the final render
6. PE (Prompt Enhancer) Settings for Photorealism
ERNIE-Image's unique PE module, fine-tuned on Ministral 3B, has a dual impact on photorealism:
When PE Is On
- ✅ Automatically enhances simple prompts with detail descriptions
- ❌ May add unnecessary stylized descriptions
- ❌ Adds inference time (requires loading an additional 3B model)
When PE Is Off
- ✅ More precise control over output style
- ✅ Faster inference speed
- ✅ More controllable for photorealism prompts
Recommended Settings
| Scenario | PE Recommendation | Reason |
|---|---|---|
| Detailed prompt (with realism keywords) | OFF | PE may override your realism keywords |
| Simple prompt (e.g., "a girl") | ON | PE automatically adds details |
| Commercial portrait | OFF | Need precise control |
| Rapid iteration | OFF | Faster speed |
7. Complete Prompt Templates (Photorealism Scenarios)
Template 1: Film Portrait

detailed skin texture, visible pores, natural skin oiliness,
point-and-shoot film camera, 35mm, front flash, candid shot,
soft natural lighting, subtle skin imperfections
Template 2: Cinematic Street Photography
Street photography, a [subject description] walking through [scene description],
cinematic lighting, 35mm film camera, film grain,
golden hour, natural colors, candid moment, shallow depth of field
Template 3: Polaroid Style

8. Competitor Comparison: Photorealism
ERNIE-Image vs Midjourney v7
| Dimension | ERNIE-Image | Midjourney v7 |
|---|---|---|
| Photorealism | ★★★★ | ★★★★★ |
| Text Rendering | ★★★★★ | ★★★ |
| Controllability | ★★★★★ (Open Source) | ★★★ (Closed Source) |
| Cost | Free (Local Deployment) | From $10/month |
Conclusion: Midjourney v7 still has an edge in artistic style and photorealism, but ERNIE-Image can significantly close the gap with the right prompt techniques.
ERNIE-Image vs Flux.2 (Klein)
| Dimension | ERNIE-Image | Flux.2 Klein |
|---|---|---|
| Photorealism | ★★★★ | ★★★★★ |
| Parameter Scale | 8B | 12B |
| Inference Steps | 8-50 | ~20 |
| Text Rendering | ★★★★★ | ★★★★ |
| VRAM Requirement | 24GB (FP16) / 4.78GB (NVFP4) | ~24GB |
Conclusion: Flux.2 Klein delivers stronger photorealism, but ERNIE-Image leads significantly in text rendering and structured layouts.
9. FAQ
Q: Turbo mode has more plastic look — is this normal?
A: Yes. Turbo is distilled via DMD+RL to 8 steps, and detail rendering is slightly weaker than the 50-step Base mode. Recommend using Turbo for iteration and Base for final output.
Q: Does text rendering ability drop when PE is off?
A: No. PE only enhances prompt descriptions — ERNIE-Image's native text rendering ability is unaffected.
Q: How to further improve photorealism?
A: You can try a two-stage workflow in ComfyUI: first sample with ERNIE-Image for 3-5 steps, then pass to another model (like Z-Image) for second-stage refinement.
Q: Is ERNIE-Image suitable for photorealistic style?
A: Absolutely, but it requires the right prompt techniques. Adding film camera keywords and skin texture descriptions can dramatically improve realism.
10. Summary
ERNIE-Image is not perfect in photorealism, but the following core techniques can significantly improve results:
- Film Camera Prompts —
point-and-shoot film camera, 35mm, front flash - Skin Texture Details —
detailed skin texture, visible pores, natural skin oiliness - Add Imperfection —
subtle skin imperfections, natural asymmetry - Turbo Iterate + Base Output — Balance speed and quality
- PE Precise Toggle — Off for detailed prompts, On for simple prompts
ERNIE-Image's real advantage lies in the combination of text rendering + structured layouts + open source free. If you need accurate text in images (posters, infographics, e-commerce) while also wanting decent photorealism, ERNIE-Image is the most cost-effective choice in 2026.
