Key Takeaways
- Upload a clear reference photo and repeat the same character description word for word.
- Change only the scene, outfit or light in each prompt, never the person.
- Edit one thing per message and always include a protect clause.
- Consistency is never perfect. Compare every result with your original.
Why Faces Change Between Images
An AI image tool creates each picture fresh. Unless you give it a strong anchor, it invents a new average face that fits your words. That is why the same prompt gives a different person each time, and why a small edit can quietly reshape your own face.
| Why the face drifts | What to do |
|---|---|
| The prompt describes the person differently each time | Reuse the same character description word for word. Only change the scene words. |
| A new chat starts from zero | Stay in the same chat, or upload the reference photo again every time. |
| Many things change at once | Change one thing per message: background, outfit or light, not all three. |
| The tool has no reference image | Upload a clear reference photo whenever the tool allows it. |
| Different lighting and camera each time | Keep the light and lens words the same for a whole set, so the face is rendered the same way. |
| Over-long, vague prompts | Short, concrete character details are easier to repeat than long poetic ones. |
| Beautifying words such as 'perfect' or 'flawless' | Remove them. They push the face toward a generic average. |

Before You Start: Use Only Faces You Have the Right to Use
Important: Use your own face, a fictional character, or a person who has clearly given you permission. Do not use photos of strangers, celebrities or private individuals, and do not make images that could mislead people about who someone is. Check the current usage rules of your AI tool, and read our AI terms and usage page.
The 5-Part Consistency Method
- Start with one clear reference photo. Front-facing, good light, no sunglasses, no heavy filter.
- Write a character description block. Short, concrete and fixed. You will paste it every time.
- Add the protect clause. Say to keep the exact face, bone structure, skin tone and expression.
- Change only the scene. Outfit, place and light can change. The face description cannot.
- Fix with short follow-ups. Name the single thing that drifted and say to keep everything else the same.
Build a Character Description Block
A character block is a short paragraph that you reuse without changing a word. Describe features that are easy to repeat. Fill every row of this table once, then keep it.
| Anchor type | Examples to repeat exactly |
|---|---|
| Age and build | a woman in her early thirties, slim build, medium height |
| Face shape | oval face, high cheekbones, soft jawline |
| Hair | shoulder-length dark brown wavy hair, side parting |
| Eyes and brows | dark brown almond eyes, thick straight eyebrows |
| Skin | olive skin tone, a small mole above the left lip, light freckles |
| Signature item | thin gold hoop earrings, a navy scarf |
4 Copy-Paste Prompts
1. The Character Block Template
Paste this at the start of every new prompt. Replace the example features with your own, and write only the scene part fresh each time.
Prompt 01
Character description block (reuse every time)
CHARACTER: a woman in her early thirties, oval face, high cheekbones, soft jawline, shoulder-length dark brown wavy hair with a side parting, dark brown almond eyes, thick straight eyebrows, olive skin tone with a small mole above the left lip, thin gold hoop earrings. Always keep exactly this face, hair and skin. SCENE: [describe only the new scene, outfit and light here]. Free from changes to the face, plastic skin, extra fingers and warped text. Add a small watermark text reading 'www.PromptsForPhotos.Com' in the bottom-right corner, small clean sans-serif font, pure white, 50% opacity, unobtrusive, not overlapping the subject.
2. First Image From a Reference Photo
Upload your reference photo with this prompt.
Prompt 02
Best for: ChatGPT · Gemini (upload your reference photo)
Use the uploaded photo as the reference for this person. Keep her exact face, bone structure, hair, skin tone and expression style. Create a new realistic photograph of the same person sitting at a small cafe table by the window, wearing a mustard sweater, soft window light from camera left, 85mm lens, f/1.8, head-and-shoulders crop. Do not change her facial identity in any way. Add a small watermark text reading 'www.PromptsForPhotos.Com' in the bottom-right corner, small clean sans-serif font, pure white, 50% opacity, unobtrusive, not overlapping the subject.
3. A New Scene, Same Person
Send this in the same chat, right after the previous image.
Prompt 03
Best for: ChatGPT · Gemini (same chat as Prompt 02)
Create another image of the same person from the previous image. Keep her exact face, hair and skin tone. New scene: walking through a green park in the morning, wearing a white linen shirt, soft golden-hour light from camera right, 50mm lens, waist-up shot. Change only the scene, outfit and light. Add a small watermark text reading 'www.PromptsForPhotos.Com' in the bottom-right corner, small clean sans-serif font, pure white, 50% opacity, unobtrusive, not overlapping the subject.
4. Edit Your Own Photo Safely
Upload your own photo with this prompt. Change one thing per message.
Prompt 04
Best for: ChatGPT · Gemini (upload your own photo)
Edit the photo I uploaded. Keep my exact face, bone structure, skin tone and expression, and do not beautify, reshape or blend my face. Change only the outfit to a dark green jacket, keeping the same pose, background and framing. Do not alter my facial identity in any way. Add a small watermark text reading 'www.PromptsForPhotos.Com' in the bottom-right corner, small clean sans-serif font, pure white, 50% opacity, unobtrusive, not overlapping the subject.
Follow-Up Messages That Fix Face Drift
When a result is close but the face has changed, do not start over. Send one short message. The vertical bars below separate four different messages, so send only one at a time.
Follow-up Set
Send ONE per message when the face drifts
The face changed. Redo the image and keep the exact face, hair and skin tone from the reference photo. | The hair changed. Keep the same hair as in the reference: shoulder-length dark brown wavy hair with a side parting. Change nothing else. | The face looks too smooth and generic. Keep everything else the same, but restore the natural skin texture and the small mole above the left lip. | Go back to the previous version and change only the background.
Tip: The same method for editing is shown step by step in our Gemini photo editing prompts guide and our ChatGPT image prompts guide.
Keeping a Whole Set Consistent
- Keep one lens and one light style across the set, for example 85mm and soft window light, and change only the place.
- Generate in one session. Do all the images for one set in the same chat, on the same day.
- Save your best version and use it as the new reference if the face drifts away from the original.
- Pick your best images at the end. Even a good method gives some misses, so generate a few extra.
What You Cannot Fully Control
No prompt guarantees an identical face. Tools update often, results change on every run, and some tools handle reference photos better than others. Treat consistency as a way to reduce drift, not remove it. If a result matters, such as a profile photo or a brand character, compare it closely with the original and reject any version that looks like a different person.
Frequently Asked Questions
Can AI keep the exact same face across photos?
Not perfectly. Tools can get close, especially when you upload a clear reference photo and repeat the same description, but small changes in the face are normal. Always compare the result with your original.
What is the best way to keep my own face in an edit?
Upload a clear, front-facing photo, start the prompt with a protect clause, and change only one thing per message. Stay in the same chat so the tool keeps the context.
Does a reference photo work better than a text description?
Usually yes, when the tool supports uploads. Use both together: the reference photo carries the face, and the repeated description reminds the tool what to keep.
Can I make a consistent character for a story or a brand?
Yes. Write one character description block, reuse it word for word, and change only the scene. Keep the lighting and lens words the same across a set so the character is rendered consistently.
Can I use another person's face?
Only with their clear permission. Do not use photos of strangers, celebrities or private individuals, and do not create images that could mislead others about who someone is. Read the usage rules of your AI tool.
Why does my character look different in a new chat?
A new chat starts without memory of the earlier images. Upload the reference photo again and paste the same character block at the start of the prompt.
Final Thoughts
A consistent face comes from repetition: one reference photo, one fixed description, one protect clause and one change at a time. Use only faces you have the right to use, test the prompts above on your own photo, and keep the character block that works best for you. Then build a whole set around it.
