Lingdong Photo

Lingdong Photo is a free, open-source, on-device photo creation app.

Choose photos to extract colors, recognize scenes, read real EXIF data, and create cards, palettes, journals, camera stamps, wallpapers, privacy masks, Photo Tickets, and sketches. You can also analyze light, compare two photos, build multi-page albums, or turn video into a Live Photo. Everything is processed on your device.

Eight creation modes: • Motion Card Create coordinated captions and colors with solid, gradient, or locally sampled backgrounds.

• Glass Palette & Light Analysis Extract six representative colors with HEX values, poetic names, and percentages. Light Analysis explains shadows, midtones, highlights, contrast, exposure, and color channels in plain language.

• Instant Journal Combine up to five photos into a collage, magazine layout, or vertical filmstrip. Reorder and frame each photo independently.

• Bubble Stamp Combine a photo, caption, dominant color, and real camera details such as lens, aperture, shutter speed, and ISO.

• Spectrum Wallpaper Generate a device-sized gradient wallpaper from your photo’s colors.

• Privacy Mosaic Mask areas manually or use on-device detection to locate faces, license plates, QR codes, and sensitive text.

• Photo Ticket Create Horizontal Classic, Vertical Travel, or Minimal Credential tickets with barcodes or verification QR codes. Customize public details, colors, width, messages, and device seals.

• Photo Sketch Turn photos into pencil, charcoal, or watercolor artwork with adjustable strokes, color, strength, and paper texture.

More tools: • Video to Live Photo Choose a three-second video segment and select its key photo frame by frame. Compatible video and audio are preserved whenever possible to avoid unnecessary recompression.

• Color Relationship Compare two photos through shared, contrasting, or transitional colors. Save a visual comparison or a complete analysis with color metrics.

• Photo Album Create Travel, Family, Children, Animals, or custom albums in A5 portrait, square, or A4 landscape format. Edit photos, text, fonts, and pages, then export a digital or print-ready PDF.

• Scan Photo Tickets Scan verification QR codes locally to view the ticket ID, photo fingerprint, device seal, shared capture details, colors, and message. App Clip lets people view shared information without installing the full app.
