combine-people

Combine a user's photo with another person (real or fictional) into a single composite image: $ARGUMENTS

Follow these steps exactly:

Step 1: Upload the user's photo

If the user provides a photo of themselves, use upload_file to upload it. Note the returned filename for use in LoadImage.

Step 2: Generate a reference image of the other person

Use KlingOmniProImageNode (model: kling-v3-omni) or GeminiNanoBanana2 to generate a high-quality reference portrait of the target person. Use a detailed prompt describing their iconic appearance. Save and upload the result for use as a second reference.

Alternatively, if the user provides their own reference image of the second person, upload that instead and skip generation.

Step 3: Batch the reference images

Use ImageBatch to combine both images into a single batch:

{
  "class_type": "ImageBatch",
  "inputs": { "image1": ["user_photo_node", 0], "image2": ["other_person_node", 0] }
}

Step 4: Generate the composite with Nano Banana 2

Use GeminiNanoBanana2 with these settings for best results:

• model: Nano Banana 2 (Gemini 3.1 Flash Image)
• thinking_level: HIGH (critical for face accuracy)
• resolution: 2K
• aspect_ratio: 16:9 (or match user preference)
• response_modalities: IMAGE
• images: connect to the ImageBatch output

Prompt structure (important):

The prompt should:

1. Explicitly state which reference image is which ("The first image is...", "The second image is...")
2. Emphasize EXACT face reproduction from both references
3. Describe clothing, pose, and setting
4. Specify lighting consistency
5. Call out any artifacts to avoid (e.g., "NO glare on glasses, NO reflections on lenses")

Example prompt:

Create a black and white vintage 1970s photograph combining these two people.
The first image is the primary reference - reproduce this man's face EXACTLY as shown:
his specific facial features, smile, dark hair style, and black zip-up jacket. He should
be on the left. The second image shows [PERSON NAME] - reproduce their face exactly as
shown with [iconic features]. They are posing together as close friends in [setting].
[Style instructions]. Important: [any artifact avoidance instructions].
