Pixel-level heuristics — not a classifier. Screenshots, heavy compression, and noise-reduction filters affect scores.
What this does: Adds realistic photographic imperfections absent in AI output.
Tip: Film Grain and Chromatic Aberration have the highest impact on automated classifiers. Keep values subtle — visible grain defeats the purpose. Camera Phone or DSLR presets are usually the sweet spot.

Google SynthID embeds an imperceptible neural watermark in pixel values. Used in Imagen 2 & 3, Gemini image generation, and Google AI image tools. Designed to survive cropping, compression, and screenshots.
Detection limit: True SynthID detection requires Google's proprietary detector model, which is not publicly available. We scan for Google-origin metadata markers and run a DCT frequency anomaly check.
