Updated Important Notes
BananaFX is currently in beta. While results can be impressive, they may not always be 100% consistent.
Group Limitations: BananaFX Real works best with 2–3 people. Larger groups may produce unpredictable results.
BananaFX Styled is recommended for single-person shots. Group shots are unpredictable at the moment while it's in beta. We recommend using group stylized imagery. Use PersonaFX Styled instead.
Works best with high-quality, well-lit photos.
⚠️ Template Recommendation: BananaFX works with square filters, and it’s recommended to use square templates or add square frames to your designs for the best results and alignment.
Known Limitations
Styled filter may not apply the style to all subjects in a group.
Faces in Styled mode may not perfectly match the original photo.
Output depends heavily on posing, clarity, and the strength of your prompt.
What is BananaFX?
BananaFX is a cloud-rendered AI filter powered by Google’s NanoBanana (Gemini 2.5) model. It transforms your guests’ original photo into a completely new AI-generated image based on your custom prompt.
The results are rendered quickly in the cloud, shared with guests via their chosen delivery method (email, SMS, etc.), and sent straight back to the booth gallery, all handled automatically within Snappic.
Snappic does not have direct control over the rendering speeds, as this rendering is done using external processing software. While results are typically fast, variations in speed can occur depending on the external service’s current performance.

➡️ Optional Survey Setup

✨ Tip: When using survey fields, click the survey field above the prompt box to insert the guest's input into the prompt. Example: "Their name appears in bold letters on their racing suit: [What is your name?]"
Prompting Tips
A strong prompt is key to getting high-quality AI output with BananaFX. The prompt is essentially your art direction. It tells the AI how to transform the guest image into something new, creative, and visually striking.
Tips:
✅ Describe everything in detail: Your prompt should cover the scene, outfit, pose, background, facial expression, lighting, and camera angle.
✅ Use language that applies to both individuals and groups: For example, use "the subject or subjects in the input image" instead of just "the guest."
✅ Include gendered styling options when relevant: If you're including outfit changes, describe both male and female versions in the same prompt.
✅ Use prompts that suggest editorial, cinematic, or fashion photography: This helps the AI anchor the visual style.
✅ Keep the structure consistent: Start with transformation context ("the subject is transformed into..."), then specify wardrobe, environment, lighting, and vibe.
✅ Use clean and direct language: Avoid too much ambiguity or multiple clashing visual elements.
✅ When using survey fields, clearly describe where that information goes in the prompt (e.g. on a shirt, a name tag, a poster background).
✅ Test all your prompts before going live — even minor changes can affect output quality.
Strong Prompt Structure:
The subject or subjects in the input image are transformed into [new identity or theme]. They are posed [pose description] and dressed in [outfit details]. The background is [scene description], and the lighting is [lighting style]. The final image feels [tone, mood, quality — e.g. high-fashion, cinematic, editorial, playful].
This format helps ensure high render quality and consistent styling across guests.
Example Prompt (BananaFX Real):
The subject or subjects in the input image are reimagined as fashion icons wearing couture crafted from blooming flowers. For female looks: gowns cascading with roses, proteas, and lilies, with flower crowns of orchids and wild blooms. For male looks: tailored floral suits with embroidered vines, lapels sprouting with fresh blossoms, and petal-woven boots. The background is a magical botanical garden in full bloom, with arched trellises of wisteria, glowing fairy lights, butterflies in flight, and a sunset sky painted pink and gold. The whole scene feels romantic, whimsical, and enchanting, like an ethereal garden ball.
Best Practices
For BananaFX Real:
✅ Works well with 1 to 3 people.
✅ Works best when subjects are posed cleanly (facing camera, upright, not cluttered).
✅ Supports pose selection.
⚠️ Group outputs can sometimes miss styling certain people — keep prompts clean.
For BananaFX Styled:
✅ Use with one person only.
✅ Works best with random pose.
✅ Works better when highly stylized (e.g. Pixar, Watercolor).
⚠️ Group photos often result in inconsistent styling or misgendering.
⚠️ Face resemblance may be lower — use stylized prompts to help.
Final Tips
🔁 Always test your prompt before going live.
⏱️ BananaFX renders faster than other filters like PersonaFX or ClassicFX.
💬 Use surveys to personalize outputs (e.g., names, preferences).
🙂 Ask guests to face forward, with a smile (no funny faces!), no wild poses.
🔆 Ensure you have good lighting at the booth, with a plain backdrop
💡 Have fun with themes — Barbie, Red Carpet, Race Car Driver, and more
