ArchCam vs Jeju Filter

ArchCam keeps buildings upright, horizons level, and people looking more natural near the edges of wide photos. See corrections while you shoot, then refine them in Studio Editor. Your original stays recoverable. AUTOMATIC VERTICAL PERSPECTIVE Point the camera up or down at buildings or interiors. Verticals uses camera orientation and lens information to straighten converging upright lines, similar to the shift movement of a perspective-control lens. MORE NATURAL WIDE PHOTOS Reduce stretching of faces and figures near frame edges in group photos and selfies. Wide uses a curved, fisheye-like projection, so straight lines may bend. It works with front and rear cameras, not just ultra-wide lenses. LEVEL HORIZONS Automatically straighten tilted horizons. For most everyday photos, this is the only correction you need. Turn it off for deliberately angled compositions. DOCUMENT AND ARTWORK MODES Document mode straightens flat subjects photographed from above with the rear camera. Artwork mode adds manual horizontal perspective for paintings, posters, and building facades photographed from one side. PREVIEW OR OUTLINE See enabled corrections live in Preview, or use Outline to show the future corrected frame with less processing and typically lower battery use. Both save the same enabled corrections. REFINE IN STUDIO EDITOR Edit ArchCam or library photos with Horizon, Vertical and Horizontal perspective, 4-Corner, Wide, and Color tools. Live Photo editing retains motion and sound; geometry edits preserve the chosen Portrait appearance. COMPARE AND KEEP Compare Original and ArchCam versions, save either, or keep both as separate photos. Review actions are free. Studio Editor and Artwork capture share 10 free saves; an optional one-time purchase removes the limit. LIVE PHOTO CAPTURE Capture motion around the full-resolution still photo, with optional sound. APPLE WATCH REMOTE Frame shots with a live view on Apple Watch, zoom with the Digital Crown, toggle Wide correction, and use a shutter timer. Keep ArchCam open on your paired, unlocked iPhone. CAMERA CONTROLS Adjust exposure and white balance, pinch to zoom, switch cameras, and shoot with either volume button. Tap to focus or touch and hold for focus and exposure lock. PRIVATE PHOTO PROCESSING Photos are processed on your iPhone, with no ArchCam account, advertising, analytics, tracking, or image-processing backend. Apple handles Studio purchases; Photos may sync through your iCloud settings.

Any landscape, Jeju-style. Jeju Filter is a landscape-only camera that turns the scene in front of you into the moods of Jeju Island. Filters apply live in the viewfinder, and after the shot you can fine-tune with sliders and save your own filter. ■ Four Jeju moods • Foggy Jeju — fog that thickens with distance. Near things stay crisp, far hills and buildings fade away. • Jeju Sunset — detects the sky and replaces it with one of five sunsets (red, golden, purple, cloudy, blue hour). The foreground goes dark like a backlit scene, and only lit surfaces glow warm. • Gotjawal Forest — deep forest greens with light haze between the leaves. • Jeju Sea — turquoise and cobalt that make the water come alive. Plus Camellia, Stone Wall, Cinema, Mono, Vintage and Night. ■ A smart camera • Recognizes the scene and puts the best-matching filter first. • Detects people automatically and keeps them out of the fog and sunset effects. • Depth estimation, scene recognition and person segmentation all run on your device. Photos never leave your phone. ■ Fine-tune and save Intensity, exposure, contrast, saturation, warmth, grain, bloom, halation and vignette sliders. Save a combination as "My Filter" and reuse it on the next shot. ■ Your photo data stays EXIF shooting data and location (if allowed) are kept in the saved photo. Results carry a small JEJU FILTER watermark. Made for landscapes, so the front (selfie) camera is intentionally not supported. Free, with occasional interstitial ads.
