Halloween AI Prompts

These prompts are written for image-editing models, including Gemini image models, ChatGPT image generation, and the models available in this studio. Each one follows the same structure: what to preserve, what to change, how to light the scene, and what to avoid.

Copy a prompt into the model you already use, or open the matching preset here to run it with your photo. The prompts are free to copy. Generation costs depend on the model and the number of images you make.

80 credits per image. Video costs more and is shown before you generate. No app install.

Halloween-themed tarot cards, a candle, and a notebook arranged as a prompt-library flat lay

Identity first

Every prompt starts by naming what must stay recognizable: face, skin tone, proportions, and the number of people.

Concrete changes

Each prompt names a specific hairstyle, garment, material, scene, and lighting direction instead of vague mood words.

Explicit negatives

Extra limbs, face swaps, text, logos, and watermarks are listed so the model has a clear boundary.

Halloween looks you can generate

Each card opens the studio with the prompt and mode already loaded. Upload a photo and press generate.

Couples and two people

Two-reference prompts. The priority is keeping exactly two identities and no third person.

Dress one person as a cinematic cowboy and the other as a luminous angel with feathered wings. Place them in a warm desert dusk scene with soft haze and lantern light. Keep exactly two people.

Ghost & Ghoul

Use two reference photos. Preserve each person’s face and identity. Dress one as a soft vintage ghost with translucent layers and the other as an elegant ghoul with charcoal fabric and silver details. Place them in a foggy graveyard with a weak moon. Keep exactly two people. Avoid face swapping, a third person, merged bodies, text, and logos.

Sun & Moon

Use two reference photos. Preserve each face and body proportion. Dress one in warm gold celestial armor and the other in silver-blue lunar robes. Place them against a twilight sky with a visible sun and moon. Keep exactly two people, with clear space between them. Avoid face swapping, extra people, merged hands, text, and watermarks.

Vampire & Victim

Use two reference photos. Preserve both identities. Dress one in a formal black vampire coat with a subtle red lining and the other in a pale period outfit with a lace collar. Place them in a candlelit manor hallway. Keep exactly two people and a consensual, non-graphic pose. Avoid gore, face swapping, a third person, text, and logos.

Background and atmosphere edits

Keep the person and costume; change only the scene. These are the safest edits.

Fog portrait

Keep the subject, face, pose, and clothing unchanged. Replace the background with dark autumn foliage, add low fog and a soft lantern glow from the left. Preserve skin texture and natural colors. Photorealistic editorial portrait. Avoid changing the face, adding people, text, and watermarks.

Keep the subject and costume unchanged. Replace the background with an autumn field, miniature pumpkins, and warm late-afternoon light. Add a gentle breeze in the hair only. Preserve identity and body proportions. Avoid changing the outfit, adding people, text, and logos.

Haunted hallway

Keep the subject and pose unchanged. Replace the room with a dim abandoned hallway, add a weak practical light and a distant window. Use cool shadows with a warm edge light. Preserve the face and clothing. Avoid jump-scare imagery, extra people, text, and watermarks.

Candlelit portrait

Keep the subject and costume unchanged. Relight the scene with warm candlelight from below and a soft cool rim light from behind. Darken the background and add subtle haze. Preserve skin tone and identity. Avoid changing the face, adding props in front of the face, text, and logos.

Short video motion prompts

Use these with a finished portrait in an image-to-video model. Keep the motion small.

Slow head turn

Use the provided image as the exact reference and first frame. Keep the face, costume, hairstyle, and body proportions consistent. The subject slowly turns their head toward the camera with a subtle expression. A light breeze moves loose hair. Fog drifts in the background. The camera pushes in slowly. No scene cuts, no identity change, no text.

Fog drift only

Use the provided image as the exact reference. Keep the subject completely still. Soft fog drifts through the background from left to right, and a distant lantern flickers gently. The camera holds steady. No face movement, no costume change, no new characters, no text.

Hair breeze

Use the provided image as the exact reference. Keep the face and body still. A gentle breeze moves loose hair and the edge of the costume. The background stays stable. Slow, smooth motion with stable anatomy. No identity change, no scene cuts, no text.

Lantern glow

Use the provided image as the exact reference. Keep the subject still. Warm lantern light gently pulses in the background while fog moves slowly. The camera pushes in a few centimeters. Maintain consistent lighting on the face. No costume change, no extra characters, no text.

What you need to know

How to use these prompts

Paste the full prompt into an image-editing model and upload a photo. If the model has a separate “negative prompt” field, move the “avoid” sentence there. If it does not, leave the sentence in the main prompt; most modern models understand it.

Change one sentence per run. If you change the hair, the costume, and the background at once, you cannot tell which change caused a problem. Keep the preservation sentence and the negatives unchanged unless you have a specific reason to edit them.

Why the prompts are structured this way

Image models are good at following concrete visual instructions and bad at guessing which parts of a photo are sacred. The preservation sentence establishes the boundary. The change sentences describe the costume. The lighting sentence controls the mood. The negative sentence blocks the most common failures.

This structure also makes prompts portable. The same recipe works in different models; only the model’s tolerance for long instructions changes. If a model truncates long prompts, keep the preservation sentence and the costume sentence, and move the scene details to a second pass.

Model-specific notes

Gemini image models tend to follow long natural-language instructions well and can edit a reference image directly. ChatGPT image generation is strong at following conversational corrections; after the first result, ask for one specific change instead of pasting a new prompt. This studio uses KIE-hosted image and video models, with 80 credits per image; video costs more and the exact amount is shown before you confirm.

If a model refuses a costume prompt, remove the brand or character name and describe the silhouette and materials instead. Original descriptions are more likely to pass and produce a usable image.

A note on permission and disclosure

Use photos you have the right to edit. Ask before uploading a friend, partner, or family member. Do not use a generated costume to imply that a real product exists or that a film or brand endorsed the image.

When you publish, label the image as AI-generated if the platform asks. The goal is a fun costume photo, not a fake photograph of a real event.

Frequently asked questions

Can I use these prompts in Gemini or ChatGPT?

Yes. Paste the prompt into an image-editing or image-generation model that accepts a reference photo. The structure — preserve, change, light, avoid — is model-agnostic. If the model has a separate negative prompt field, move the “avoid” sentence there.

Are the prompts free?

The prompts on this page are free to copy. Running them in this studio costs 80 credits per image; video costs more and the exact amount is shown before you confirm. Running them in another model costs whatever that provider charges.

Why do the prompts repeat what to preserve?

Image models tend to change whatever is not explicitly protected. Repeating the face, skin tone, proportions, and number of people is the most reliable way to keep a costume edit looking like the same person.

Can I remove the copyright-safe wording?

You can edit the creative sentences, but be careful with named characters and brands. The original descriptions in these prompts are intentionally generic so the result is an homage, not a copy. If you name a copyrighted character, you take on the legal and platform risk.

Which prompt should I try first?

Start with a single-person portrait such as Midnight Braids or Cosmic Princess. They are the easiest to evaluate: one face, one costume, one background. Move to couples and video after you have a still you like.
