How do I enter AI prompts in Snappic?

In Snappic, AI prompts are entered in the PersonaFX or BananaFX configuration panel under the AI Style field. Open your event configuration, navigate to the AI processing section, and paste your prompt text directly into the style prompt field. The prompt applies to all captures during the event.

What is the difference between Snappic PersonaFX and BananaFX?

PersonaFX focuses on portrait-preserving AI transformations that maintain subject likeness while applying stylistic treatments. BananaFX offers more dramatic transformations with higher creative latitude. Both accept text-based prompts. PersonaFX is better for formal events; BananaFX excels at bold, high-energy aesthetics.

What is Snappic PBX and how do prompts work with it?

Snappic PBX is the professional conference version of Snappic used at industry events like Photo Booth Expo. It uses the same PersonaFX and BananaFX AI engines with the same prompt syntax. PBPrompts generates PBX-compatible prompts that work identically to standard Snappic deployments.

How long should a Snappic AI prompt be?

Snappic prompts perform best at 40–80 words. Include style description, lighting direction, color palette, and composition guidance. Avoid technical parameters like CFG scale, steps, sampler names, or LoRA weights — Snappic handles these internally. PBPrompts automatically formats prompts within the optimal length range.

Can I use the same prompts for PersonaFX and BananaFX?

Generally yes — the same prompt text can be used in both engines, though the visual interpretation will differ based on each engine's style. For events where you want consistent, predictable outputs, stick with one engine per event. Test both with your prompt in advance to see which produces the aesthetic you prefer.

Why It Matters

Why Snappic operators need purpose-built prompts

Snappic's PersonaFX and BananaFX AI engines are powerful, but generic prompts produce generic results. The difference between a forgettable output and a "can I get another?" moment is almost always in the prompt specificity. Operators who use vague style descriptions like "oil painting" get inconsistent results that vary wildly from shot to shot. Prompts that specify lighting direction, subject framing, and color palette give PersonaFX the context it needs to produce consistent, high-quality outputs across every capture.

Snappic also has specific syntax preferences that most prompt-writing guides miss. Technical parameters like CFG scale, steps, and sampler settings should never appear in Snappic prompts — the platform manages these internally and including them can confuse the AI processing pipeline. PBPrompts generates prompts that work with Snappic's architecture rather than against it.

Sample Snappic PersonaFX Prompt

Cinematic magazine cover portrait, subject in formal attire, editorial three-point studio lighting with crisp rim separation, deep blue and gold color grade, sharp subject focus with soft background gradient, Vogue fashion editorial aesthetic — polished, high-fashion, and instantly shareable.

PersonaFX vs BananaFX

Choosing between PersonaFX and BananaFX for your event

PersonaFX is the right choice when client expectations center on recognizable, elevated portraits — weddings, corporate events, galas, and formal celebrations where guests want to look like themselves but better. It excels at soft-to-medium stylistic transformation with high subject fidelity. Prompts for PersonaFX should emphasize portrait quality, lighting precision, and color grade direction.

BananaFX is for events where the wow-factor goal is dramatic transformation — turning guests into movie characters, fantasy figures, or editorial cover subjects. High-energy social events (sweet 16s, quinceañeras, club nights) tend to favor BananaFX outputs. The same prompt can be loaded into both engines, but the visual results will differ — test both before the event to choose the better fit.

Style Transfer

Snappic Style Transfer prompts — what operators need to know

Snappic's Style Transfer feature applies a visual style from a reference image to booth captures in real time. Unlike PersonaFX and BananaFX which use text prompts, Style Transfer is driven by image references — but pairing a strong text prompt in the AI Style field alongside your Style Transfer reference image significantly improves output consistency and directs the AI when the reference is ambiguous.

Best practice: upload a high-contrast, well-lit reference image with a clear aesthetic (not a photo of a person you want to replicate — a mood board or editorial shot works best). Then generate a complementary text prompt in PBPrompts that reinforces the same lighting, color, and style direction as your reference. This two-layer approach gives Snappic's AI the clearest possible signal.

Style Transfer is especially powerful for corporate brand events where you have a client's brand guidelines to match — upload a branded visual and generate a prompt that names the brand colors and aesthetic. The result is consistently on-brand outputs that clients screenshot and share.

Style Transfer Companion Prompt (pair with your reference image)

Brand editorial portrait, subject centered with clean negative space, corporate lighting with soft side fill, brand-aligned color grade in cobalt blue and silver tones, sharp professional focus, LinkedIn-ready composition — polished, modern, and on-brand for every capture.

ClassicFX

ClassicFX and ClassicFX Group prompts for Snappic

ClassicFX is Snappic's legacy AI engine, distinct from PersonaFX and BananaFX. It uses a different prompt interpretation model that responds better to shorter, more directive prompts. Where PersonaFX prompts perform best at 40–80 words with rich descriptive language, ClassicFX outputs are more consistent with prompts in the 20–40 word range that lead with the core style rather than building up context.

ClassicFX Group prompts are used when multiple subjects are present in a single capture. Standard single-subject prompts can cause the AI to focus inconsistently across multiple people. ClassicFX Group mode applies the transformation more uniformly across the frame, which is critical for corporate team shots, family portraits, and group event captures.

ClassicFX Single Subject — Short Form

Oil painting portrait, warm candlelight tones, impressionist brushwork, museum quality framing, rich amber and umber color palette.

ClassicFX Group Prompt — Multi Subject

Ensemble editorial portrait, equal studio lighting across all subjects, neutral background, cohesive warm color grade, professional group composition, sharp and clean output.

PBPrompts lets you select group size in the generator — choose "Group" under the subject field and the output will automatically adjust prompt structure for ClassicFX Group compatibility.

Negative Prompts

Snappic negative prompts — how and when to use them

A negative prompt tells Snappic's AI what to avoid — artifacts, unwanted styles, or compositional problems that appear when the positive prompt isn't specific enough. Snappic accepts a separate negative prompt field in its AI configuration panel. Used correctly, a negative prompt tightens output quality and eliminates the most common failure modes: blurry details, extra limbs, color banding, and low-resolution artifacts.

Not every event needs a negative prompt — if your positive prompt is specific and producing good results, leave the negative field minimal. Negative prompts are most useful when you're seeing consistent issues with a particular output pattern, or when working with Snappic's ClassicFX engine which is more sensitive to artifacts than PersonaFX.

General Purpose Snappic Negative Prompt

blurry, out of focus, low quality, pixelated, extra limbs, deformed hands, watermark, text overlay, cartoon, anime, illustration, artificial skin texture, overexposed, color banding, noise, grainy, bad composition, cropped face

Corporate Event Negative Prompt

casual clothing, messy background, harsh shadows, overexposed highlights, cluttered composition, informal pose, low resolution, artifacting, text, watermark, cartoon, sketch

PBPrompts Pro automatically generates a matching negative prompt alongside every positive prompt — copy both into Snappic's configuration for the best results.
