Latent显影
Develop what's hidden in your photos — the real EXIF, the real colors, the real light. Every pixel of it on your iPhone.
Your shot's real story
Latent reads the EXIF your camera actually wrote — camera, lens, aperture, shutter, ISO — and sets it under your photo. A missing field stays blank; it never invents a lens or a shutter speed.
Four styles, five faces
Film border, date stamp, minimal card, and bubble stamp — each with an adjustable title, caption, and typography.
Smart captions
On-device scene recognition suggests a fitting one-line caption, deterministic per photo. Shuffle for more.
Moment Restore
Golden hour, the weather at the shutter press, the moon phase that night — recomputed from the photo's own timestamp and place with local astronomy.
Colors with names worth reading
A draggable glass palette lifts 3–6 dominant colors from your photo with exact proportions, each traceable to the pixels it came from. Every color is named twice — an English literary name, and a Chinese traditional color in pinyin and hanzi.
See what a photo reveals
Latent detects faces, license plates, readable text, and barcodes on-device, and lets you blur, mosaic, or block them. Metadata removal is verified by re-reading the exported file. Live Photos always export as stills here — motion frames can leak the very thing you just redacted.
Cards that move
Creative exports keep the motion; the privacy path never does. And a journal page arranges itself from up to five photos.
Live Photo export
Cards and glass palettes render onto every motion frame and save back as a real Live Photo — press to play, chrome intact.
Journal collage
Pick up to five photos; the layout arranges itself, and captions adapt their contrast to whatever sits beneath them.
EXIF viewer
Every field your photo carries — camera, exposure, GPS with map, file details — grouped, readable, and copyable.

Questions, answered
What is Latent?
Latent (显影, “to develop a photograph”) develops what is already hidden inside your photos — the EXIF, the colors, the light — into shareable art: film cards, palettes, moment lines, journals. And before anything leaves your phone, its privacy kit shows what the photo would reveal.
Does Latent upload my photos anywhere?
No. Everything runs on your iPhone — no accounts, no analytics, no ads, no servers. The single optional network call, historical weather, is off by default and sends only rounded coordinates and a date to the Open-Meteo public archive.
What are the Chinese traditional color names?
Centuries-old color words like Yanzhi 胭脂, Tianqing 天青, and Qinglian 青莲, shown in pinyin and hanzi alongside English literary names. Latent's color tables are our own curated work.
Does Latent invent camera data for the cards?
Never. Cards show only what the photo actually carries. A missing lens or shutter speed stays blank — real data or nothing.
Why does the Privacy Kit export Live Photos as stills?
A Live Photo's motion frames can contain the exact content you just blurred in the key frame, so the Privacy Kit exports stills only. Creative exports — cards, palettes, collages — can keep the motion.
Which languages does Latent support?
English, Simplified Chinese (as 显影), Spanish, and Japanese. The app follows your iOS system language automatically.
