Important Notes

Uses 2 credits per generation.
One person per image only (use ClassicFX Group for multi-person effects).
Be specific in your prompt (e.g., “A cyberpunk warrior with neon lights and a futuristic helmet”).
Use both positive (desired) and negative (unwanted) prompts for fine-tuning.
Do not overload prompts with conflicting details — clarity gives better results.
Processing starts only after upload completes (average time: 2–5 minutes).
Upload times vary by internet speed, image size, and network congestion.
No guaranteed processing time — high traffic can increase queue duration.
Background removal is supported for all ClassicFX filters.
Sharing: AI outputs can be sent via email or text once the session syncs.
Printing: To print AI-FX images, use a Sharing Station.
Virtual Booth: Not supported.
Animated backgrounds: Not supported.

Known Limitations

AI results may include unexpected variations in facial features, gender, or skin tone.
NSFW filtering is active, but nudity or artistic exposure may still occur in both Real and Styled modes.
Sharing via QR code or AirDrop only sends the original image unless you share the AI output directly from the app.
Prompts with excessive details can reduce accuracy or create distortions.
AI-FX only begins after all uploads are completed — large or slow uploads may delay processing.

What is ClassicFX?

ClassicFX gives you the power to completely transform your guests’ photos using AI and text prompts.

You can define:

The subject’s look, pose, and clothing
The background (AI-generated, custom, or uploaded)
The overall mood or art style
The influence of reference imagery

This flexibility allows you to create anything from professional headshots to cinematic fantasy portraits — all from a single photo booth capture.

ClassicFX Real vs Classic FX Stylized

ClassicFX Mode	Description	Best For	NSFW Filtering
Real ClassicFX	Produces photorealistic results with lifelike skin, lighting, and texture.	Corporate headshots, vintage looks (e.g., 80s, Hollywood), professional branding.	NSFW filtering included; nudity may still occur occasionally.
Styled ClassicFX	Creates artistic or fantasy-style results inspired by illustration, anime, or painting aesthetics.	Comic book or anime looks, painted portraits, creative or themed events.	NSFW filtering included; artistic nudity may occur.

Setting up ClassicFX in Snappic

You can configure both Real and Styled Custom Prompts using the same setup process. Below is a shared walkthrough to help guide you through the interface.

Step 1:

Open your event in the Snappic dashboard.
Go to the Features tab and enable AI Experience. Click Save Changes

Step 2:

Go to the AI Experience section in your event dashboard.
Click + Add AI Filter and select ClassicFX Real or Classic FX Styled

Step 3:

Once you have your filter selected, click on edit to find the settings
Choose Combined (one prompt for all genders) or Separate Genders (different male/female prompts only).
Enter your Custom Prompt(s). Example: pirate, detailed clothing, on a ship, ocean background.
Add a Negative Prompt (e.g., blurry, distorted face, text overlay, extra limbs, NSFW).

Prompting Tab

Use the Prompting Tab to define the creative instructions for your AI output.

Prompt Type Options:

Combined → Same style for everyone.
Separate Genders → Distinct male/female prompts (e.g., tuxedo for men, gown for women).

Prompt Writing Tips:

Include both the subject and the scene.
- Example: “A medieval knight in silver armor, standing on a battlefield at sunset.”
Avoid vague phrases like “make it cool” or “trendy look.”
Add a Negative Prompt to block unwanted elements:
“blurry, distorted face, text overlay, extra limbs, NSFW, nudity.”
Test several variations to find the best balance.

Pose Selection Tab

Choose from:
- Original Pose (Uses original body shape)
- 3/4 Body
- Half Body
- Upper Body
- Head & Shoulders
- Random

“Original Pose” preserves the original framing of your photo.

Use “Head & Shoulders” for clean portrait framing.

Background Tab

Select Background Type:
- From Original Generation – Uses the AI-generated background from your main prompt.

Separate Prompt – Allows you to describe a new background (e.g., "moonlit forest" or "neon-lit cityscape") independent of the primary prompt.

Custom Image (static only) – Lets you upload a specific background image that remains unchanged in the final output. Perfect for Branding events . Select a clear photo or artwork that showcases the style you want (e.g., a fashion photo, movie still, or

Custom Image as Style Reference – Uses your uploaded image to influence the background’s look and feel (lighting, color palette) without replicating it exactly.

Style Reference Tab

You can upload a reference image to guide the artistic style and composition of your output.

Options & Adjustments:

Toggle “Use Style Reference Image” → Yes/No
Upload a Style Image (e.g., a fashion photo, painting, or film still)
Style Strength – Adjusts color, lighting, and texture influence.
Composition Strength – Affects subject positioning and structure.

Guidelines: ✅ Use clean, high-quality, well-lit images.

⚠️ Avoid blurry, low-contrast, or cluttered reference images.

🎨 High strength → more stylized look.

🧟 Low strength → keeps original facial features and structure.

Additional ClassicFX Notes

Original clothing cannot be retained in ClassicFX-generated images.
- For results closer to original attire, try PersonaFX or Banana filters.
- However, as with all AI-generated outputs, exact replication isn’t guaranteed.
AI output variation is normal — each render is unique even with identical prompts.
AI-FX images are shared only when sessions are synced with the Snappic app.
Background removal now available on ClassicFX filters.

Best Practices / Prompting Tips

Use Real Mode for corporate or branding work, with a custom uploaded background for consistency.
Use Styled Mode for themed or artistic events.
Begin with simple prompts, then add descriptive details (e.g., lighting, mood, wardrobe).
Avoid overloading prompts with mixed styles (e.g., “anime watercolor oil painting realistic.”)
For gender-specific designs, select Separate Genders.
Always include a Negative Prompt to refine quality.
Good prompt example:
“A futuristic space explorer wearing a silver suit, glowing helmet visor, standing on Mars at sunset.”
Poor prompt example:
“Cool sci-fi look with random background.”
