Follow these tips to change your image like a pro using QIE and Flux.2 Klein 🤙

This article originally described prompting for Qwen-Image-Edit, but initial testing shows that the same prompt tips also work with Flux Klein. I will correct this article if any differences become apparent.

"I’ve been experimenting with Qwen-Image-Edit, and honestly… the difference between a messy fail and a perfect edit is just the prompt. Most guides only show 2–3 examples, so I built a full prompt playbook you can copy straight into your workflow.

This covers everything: text replacement, object tweaks, style transfer, scene swaps, character identity control, poster design, and more. If you’ve been struggling with warped faces, ugly fonts, or edits that break the whole picture, this guide fixes that."

📚 Categories of Prompts

⸻

📝 1. Text Edits (Signs, Labels, Posters)

Use these for replacing or correcting text without breaking style.

• Replace text on a sign

For example:

Replace the sign text with "GRAND OPENING". Keep original font, size, color, and perspective. Do not alter background or signboard.

• Fix a typo on packaging

For example:

Correct spelling of the blue label to "Nitrogen". Preserve font family, color, and alignment.

• Add poster headline

For example:

Add headline "Future Expo 2025" at the top. Match font style and color to existing design. Do not overlap the subject.

⸻

🎯 2. Local Appearance Edits

Small, surgical changes to an object or clothing.

• Remove unwanted item

For example:

Remove the coffee cup from the table. Keep shadows, reflections, and table texture consistent.

• Change clothing style

For example:

Turn the jacket into red leather. Preserve folds, stitching, and lighting.

• Swap color/texture

For example:

Make the car glossy black instead of silver. Preserve reflections and background.

⸻

🌍 3. Global Style or Semantic Edits

Change the entire look but keep the structure intact.

• Rotate or re-angle

For example:

Rotate the statue to show a rear 180° view. Preserve missing arm and stone texture.

• Style transfer

For example:

Re-render this scene in a Studio Ghibli art style. Preserve character identity, clothing, and layout.

• Photorealistic upgrade

For example:

Render this pencil sketch scene as a photorealistic photo. Keep pose, perspective, and proportions intact.

⸻

🔎 4. Micro / Region Edits

Target tiny details with precision.

• Fix character stroke

For example:

Within the red box, replace the lower component of the character ‘稽’ with ‘旨’. Match stroke thickness and calligraphy style. Leave everything else unchanged.

• Small object replace

For example:

Swap the apple in the child’s hand with a pear, keeping hand pose and shadows unchanged.

⸻

🧍 5. Identity & Character Control

Preserve or swap identities without breaking features.

• Swap subject

For example:

Replace the subject with a man in sunglasses, keeping pose, outfit colors, and background unchanged.

• Preserve identity in new scene

For example:

Place the same character in a desert environment. Keep hairstyle, clothing, and facial features identical.

• Minor facial tweak

For example:

Add glasses to the subject. Keep face, lighting, and hairstyle unchanged.

⸻

🎨 6. Poster & Composite Design

For structured layouts and graphic design edits.

• Add slogan without breaking design

For example:

Add slogan "Comfy Creating in Qwen" under the logo. Match typography, spacing, and style to design.

• Turn sketch mock-up into final poster

For example:

Refine this sketched poster layout into a clean finished design. Preserve layout, text boxes, and logo positions.

⸻

📷 7. Camera & Lighting Controls

Direct Qwen and Flux.2 Klein like a photographer.

• Change lighting

For example:

Relight the scene with a warm key light from the right and cool rim light from the back. Keep pose and background unchanged.

• Simulate lens choice

For example:

Render with a 35 mm lens, shallow depth of field, focus on subject’s face. Preserve environment blur.

⸻

💡 Pro Tips for Killer Results

•	Always add “Keep everything else unchanged” → avoids drift.

•	Lock identity with “Preserve face/clothing features”.

•	For text → “Preserve font, size, and alignment”.

•	Don’t overload one edit. Chain 2–3 smaller edits instead.

•	Use negatives → “no distortion, no warped text, no duplicate faces.”

Extra tips from the comments on the original Reddit piece:

• "Prompting for natural lighting also seems to help realism"

• "What's a good prompt example for face swap or combining characters?"
  "Try this - Replace the person’s face in this photo with the face from the second image. Keep hairstyle, body pose, clothing, and background unchanged. Blend the new face naturally with lighting and skin tone."

• "You can adjust lighting on a character using descriptive text prompts that focus on camera angles or light source positions. While precise numerical angles aren’t supported, you can describe the lighting relative to the camera angle for realistic results.

  Example Prompt: Change the lighting on the character to come from directly above, simulating a top-down camera angle, with soft shadows under the eyes and chin, maintaining a cool, moonlight glow."

Editing Photos & Photoreal Gens with Flux2.Klein

👉 Original guide created by u/JIGARAYS

u/JIGARAYS says:

"The Problem: If you are using Flux 2 Klein (especially for restoring/upscaling old photos), you've probably noticed that as soon as you describe the subject (e.g., "beautiful woman," "soft skin") or even the atmosphere ("golden hour," "studio lighting"), the model completely rewrites the person's face. It hallucinates a new identity based on the vibe.

The Fix: I found that Direct, Technical, Post-Processing Prompts work best. You need to tell the model what action to take on the file, not what to imagine in the scene. Treat the prompt like a Photoshop command list.

If you stick to these "File-Level" prompts, the model acts like a filter rather than a generator, keeping the original facial features intact while fixing the quality."

The "Safe" Prompt List:

1. The Basics (Best for general cleanup)

remove blur and noise

fix exposure and color profile

clean digital file

source quality

2. The "Darkroom" Verbs (Best for realism/sharpness)

histogram equalization (Works way better than "fix lighting")

unsharp mask

micro-contrast (Better than "sharp" because it doesn't add fake wrinkles/lashes)

shadow recovery

gamma correction

3. The "Lab" Calibration (Best for color)

white balance correction

color graded

chromatic aberration removal

sRGB standard

reference monitor calibration

4. The "Lens" Fixes

lens distortion correction

anti-aliasing

reduce jpeg artifacts

"My 'Master' Combo for Restoration:"

clean digital file, remove blur and noise, histogram equalization, unsharp mask, color grade, white balance correction, micro-contrast, lens distortion correction.

"TL;DR: Stop asking Flux.2 Klein to imagine 'soft lighting.' Ask it for 'gamma correction' instead. The face stays the same, the quality goes up."
