Booth Mode AI Effects transform a photo after it’s captured. You can enter a custom prompt or choose one from our library of publicly available prompts.
You can use them to turn people into cartoons, apply a glam-style retouch, create cinematic looks (for example, a dramatic film scene effect), and more.
If you want guests to further personalize their results, you can enable Guest Input Settings to let them make choices that affect the final image.
Internet Requirement
Booth Mode AI Effects generate images in real time, so an active internet connection is required.
Slower networks will increase processing time
Test your network before the event.
Have a backup option (such as a hotspot) if possible.
Participant Experience
When a participant takes a picture that has a Booth Mode AI Effect:
They take their photo normally.
If guest inputs are enabled, they answer those prompts.
A processing screen appears while the AI image generates.
If regeneration is enabled, they can generate a new version (within your set limit).
They can then continue editing or proceed to sharing

Effect Settings
These are the general settings that control how the effect behaves.
Choose an AI Model
The model affects image style and output and determines how many credits are used per generated layout.
Model | Credits Per Generation |
Nano Banana Fastest model, individual participants. | 1x |
Nano Banana 2 Balance of speed and quality, for groups up to 5 people. | 2x |
Nano Banana Pro Slower, best quality, for groups up to 5 people. | 3x |
Allow Guest Regenerations (Optional)
If enabled, participants can regenerate their AI image if they don’t like the first result.
You can:
Turn regeneration on or off
Limit how many times a participant can regenerate
Below these settings, you’ll see a Cost per Layout section showing:
Credits used per layout
The maximum possible credits per session (including regeneration attempts)
This helps you estimate usage before your event.
Prompt Settings
Prompt Settings control how the AI transforms the image.
If you’re using a multi-frame layout, you will create a unique prompt for each frame.
Your first frame prompt is created by default. Use the + button to add prompts for additional frames.
For each prompt:
Select a style from the dropdown (examples: film noir, cartoon), or enter a custom style.
Choose whether to Preserve Poses.
On: Keeps subjects in their original pose.
Off: Allows AI to adjust poses to fit your prompt.
Choose whether to Touch Up Appearances, which smooths skin and minor blemishes.
Write your prompt. Be specific and descriptive, and see the AI prompt guide for tips.
Upload a test image.
Make sure subjects are clearly visible.
If using Nano Banana, upload a single-subject photo.
Group photos can be used with Nano Banana 2 or Nano Banana Pro.
Click Test Prompt to generate a preview.
Adjust your prompt as needed.
Recommended: Save the generated image as the effect preview so participants can see an example of what their photo will look like. You can replace the preview image with a new version anytime.
Save and close the prompt settings.
If using multiple frames, repeat these steps for each frame.
Guest Input Settings (Optional)
Guest Input allows participants to influence how their photo is generated.
For example, you could let them choose a theme, color, or enter custom text.
To add guest input:
Tap the + button in Guest Input Settings.
Select a prompt type:
Text — Participants enter their own response.

Enter a prompt placeholder.
This is the variable name used inside your AI prompt (for example:favorite_color).Insert the variable name into your prompt description surrounded by double braces.
{{example}}
Enter the question participants will see.
Configure response options:
Text prompts: Add an example value (for example, “blue”) to guide responses.
