You can use them to turn guests into cartoons, apply glam-style retouching, or create cinematic scenes. *** ### Participant Experience {% tabs %} {% tab title="HALO app" %} 1. **Pre-Capture**: If you have multiple layouts enabled, participants can choose which one to use. If you have generated AI previews, they will be able to see an example of the output before taking their photo. 2. **Capture:** The participant takes their photo normally. 3. **Guest Inputs (Optional)**: If [**Guest Inputs**](/ai-effects/post-capture-ai-effects/guest-inputs.md) are enabled, they answer those prompts. 4. **Processing:** A processing screen appears while the AI generates the image. 5. **Regeneration:** If enabled, the guest can generate a new version (within your set limit). 6. **Edit/Share:** The guest proceeds to the final editing or sharing screen. {% hint style="danger" %} **Internet Requirement** 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 cellular hotspot, available. {% endhint %} {% endtab %} {% tab title="Virtual Booth" %} When AI is enabled with Virtual Booth: 1. ​**Capture:** Guests take their photo normally. 2. **Guest Inputs (Optional)**: ​If guest inputs are enabled, they answer those prompts. 3. **Processing:** ​A processing screen appears while the AI image generates. 4. **Regeneration:** ​If regeneration is enabled, they can generate a new version (within your set limit). 5. ​**Edit/Share:** They can then continue editing or proceed to sharing {% endtab %} {% endtabs %} *** ### Creating an AI Effect 1. Open the [**AI Effects page**](https://app.simplebooth.com/ai-effects). * AI Effects can also be created directly in the Layout Designer's **Inspector settings**. 2. Select the **+** button to create a new effect, or browse the library of premade public effects. 3. Give your Effect a title, save it, then customize the remainder of the settings, described below. 4. Add your Effect to a preset. * [Adding AI Effects to HALO](/customization-guide/layout-designer/adding-layers.md) * [Adding AI Effects to Virtual Booth](/virtual-booth-setup/branding-and-customizations/picture-customizations/ai-effects.md)
#### Managing Your Effects From your [AI Effects library](https://app.simplebooth.com/ai-effects), you can perform the following actions: * **Rename**: Update the display name of your effect. * **Make a copy**: Duplicate an effect to use as a starting point for a new design. * **Favorite**: Star effects to easily find them in your library later. * **Delete**: Permanently remove an effect from your account. *** ### Effect Settings & Model After saving your effect, use these settings control the overall behavior, style, and credit cost of the transformation. #### Model & Credit Usage The AI model affects the style and credit cost.
ModelCredits 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
#### **Allowing Guest Regenerations** Enable this to let participants try again if they aren't satisfied with the first result. You can set a specific limit on regenerations to manage your credit usage. {% hint style="info" %} A **Cost per Layout** is displayed within the prompt settings. It updates as you adjust your settings, showing: * Credits used per layout * The maximum possible credits per session (including regeneration attempts) {% endhint %} #### Style & Preservation * **Quick Style:** Apply a preset style such as Cinematic, Studio Portrait, Black & White, or others. Select from a dropdown menu/ * **Subject Preservation:** Use the checkboxes for **number of subjects**, **poses**, and **expressions** to control how much of the original photo remains intact. * **Enhance:** Automatically touches up features for a polished "glam" look. *** ### Writing Prompts Prompt Settings control exactly how the AI transforms each image. If you're using a multi-frame layout, create a unique prompt for each frame within the effect's settings. {% stepper %} {% step %} #### Write your prompt Prompts can be up to 10,000 characters. There are three ways to start: * **From scratch** — begin with an empty prompt and write everything yourself. Be specific and descriptive. * **From description** — give a short idea and we'll expand it into a full prompt you can refine. * **From image** — upload a reference and we'll seed a full prompt you can refine. {% endstep %} {% step %} #### Add [guest inputs](https://docs.simplebooth.com/ai-effects/post-capture-ai-effects/guest-inputs) (optional) Guest Inputs let participants influence how their photo is generated. Once you've saved a guest input, insert it into your prompt by clicking the input (shown at the bottom of the prompt screen). You can also insert a guest input by typing it into your prompt between a pair of double curly braces, like `{{example}}`. {% endstep %} {% step %} #### Save the prompt and generate a thumbnail Select or upload a test image from your device or our library. Use a single subject for Nano Banana, and group photos for Nano Banana 2 or Pro. You can select or upload a new test image at any time. {% endstep %} {% step %} #### Refine the prompt description (optional) If the thumbnail differs from the output you want, adjust your description, then save and generate an updated thumbnail. Repeat until you're happy with the results. {% endstep %} {% step %} #### Generate previews Automatically generate previews for every possible aspect ratio. These previews appear to guests on the in-app **Choose Layouts** screen when you have multiple layouts enabled. {% endstep %} {% step %} #### Add multiple prompts To apply AI effects to a multi-frame layout (like a 1×3 photo strip), repeat the steps above to add a prompt for each frame. {% hint style="info" %} Prompts map to frames in order: prompt 1 applies to frame 1, prompt 2 to frame 2, and so on. {% endhint %} {% endstep %} {% endstepper %} *** {% hint style="success" %} ## Plan Availability **Use Public Effects** :white\_check\_mark: Core, Plus, Pro, Select :x: Lite **Write Custom Prompts** :white\_check\_mark: Plus, Pro, Select :x: Lite, Core **Write Custom Guest Inputs** :white\_check\_mark: Pro, Select :x: Lite, Core, Plus {% endhint %} --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.simplebooth.com/ai-effects/post-capture-ai-effects.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
