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.
