Apple iPhone App of the Year, 2019 Introducing Spectre, from the makers of Halide, one of the top camera apps in the App Store. Spectre uses AI to help you make amazing long exposure photographs. Spectre can remove crowds, turn city streets into rivers of light, make waterfalls look like paintings, and much more. Until now, it was difficult to take long exposures: from keeping the camera steady to guessing the amount of light you need. Spectre takes care of all of that! WHAT YOU CAN DO • MAKE CROWDS DISAPPEAR: Spectre helps take photos of crowded, touristy places. Simply set a medium or long duration and take a shot to erase the crowd from a location. Capture the those special moments like you remember them. • RIVERS OF LIGHT: At night, AI scene detection automatically switches modes to draw beautiful light trails, for stunning nighttime city photography or light painting. • GORGEOUS WATER: Capture waterfalls, ocean waves, fountains and more with beautiful ghostly water. LIVE PHOTOS AND VIDEO Spectre’s intelligent computational shutter takes hundreds of shots over the span of a few seconds, and saves them in an accompanying live photo. That means you can pick a different frame as your photo, apply live-photo effects, and even use the long exposure as a live-wallpaper! ENDLESS SMARTS Spectre is a packed with powerful technology from by the team that brought you Halide. From machine learning-based scene detection to computer vision aided image stabilization, Spectre is jammed full of impressive technologies to get the best possible image. DESIGNED FOR HUMANS Spectre is meticulously designed. Its dark UI is gentle on the eyes when you shoot at night. Gorgeous glowing highlights infuse it with a unique style. Custom typefaces and iconography combined with unique, smooth controls make it as tactile and delightful as an actual physical camera. Like its sister app Halide, the app is easily usable with one hand, even on the largest iPhones. HIGH-TECH SHOWCASE Build with the latest tech, Spectre isn't just a long exposure camera — it’s the cutting edge technology showcase of one of the App Store’s foremost camera apps, Halide. Here’s just a few of the latest technologies that we use in Spectre: - DCI-P3 Wide Color Pipeline - Live Photos - Metal Graphics Acceleration - Tripod Detection - Siri & Shortcuts - AI Stabilization - Machine Learning & CoreML - Computer Vision COMPATIBILITY: Spectre’s smart Automatic Scene Detection requires iOS 12. AI-based stabilization features are available on iPhone 6S and later.* For the best experience, we recommend iPhone 8 or later. On iPhone 6, Spectre captures in lower resolution.
