Even Longer is a professional long-exposure camera for iPhone and iPad — and the first long-exposure app on the App Store to shoot 48 MP and Apple ProRAW. You set the exposure — a duration or a frame count. The camera captures a continuous frame sequence to that target and merges it live on the GPU, under full manual control. Thirty seconds or three hours is a number you enter, not a shutter you hold. What lands in your library is a real RAW. iPHONE 18 PRO VARIABLE APERTURE Supported from day one: an aperture button and ruler on the camera screen, every stop the lens offers, and the f-number in your files. On iPhones with a fixed iris the control simply stays hidden. 48 MP AND APPLE PRORAW Long exposures at the sensor's full 48-megapixel readout, and merged results written as Apple ProRAW. Maximum resolution works in frame averaging with ProRAW, TIFF, HEIC or JPEG on iPhones with a 48 MP sensor; ProRAW needs a ProRAW-capable iPhone. RAW OUTPUT, AND SHADOWIQ Merged results save as RAW (DNG), Apple ProRAW, TIFF, HEIC or JPEG — with a fallback order you control. When a lens or mode can't produce the format you picked, the camera saves the next one it can and tells you why, without ever changing your choice. The RAW is worth the wait: dramatically more detail in the shadows and cleaner blacks than any earlier version, and ShadowIQ goes further still: shadow detail with even less noise, and no need to bracket exposures any more. WHAT YOU CAN SHOOT • Frame averaging — silky water, cleaner night shots, crowds that fade away (a computed ND filter) • Light Trails — traffic, light painting, fireworks • Star Trails — with a celestial overlay that projects the pole, constellations and the expected trails onto your viewfinder before you commit FULL MANUAL CONTROL ISO, shutter, focus, white balance, EV and aperture — with live histogram, grid and spirit level overlays, tap-to-focus and a loupe. Per-lens focal length, sensor size and crop factor are measured on your hardware, so your metadata is right. PLAN AND AUTOMATE Schedule a capture for sunset or astronomical night on the built-in sun-altitude timeline, run the intervalometer for sequences, and let interim saves protect long exposures against interruptions. REMOTE CONTROL AND APPLE WATCH Pair the Even Longer Remote app (iPhone, iPad or Mac) and control the camera from a distance: live viewfinder, full manual control, live progress, and finished files delivered to the controller. Pairing is TLS-secured on your local network; an off-grid hotspot mode works in the field without any router. The Apple Watch app — live viewfinder, shutter, progress — comes with the app. THE APP, AND PRO — READ BEFORE BUYING Even Longer is a paid app: one purchase, no ads, no data collection, nothing sold on. It gets you the whole camera — every accumulation mode, JPEG and HEIC output including 48 MP, variable aperture, histogram, grid and spirit level, the Apple Watch app and the iPad layout. PRO is an optional in-app purchase that upgrades this app — monthly, yearly, or once and forever. These features are NOT included without PRO: RAW (DNG), Apple ProRAW and TIFF output, ShadowIQ, the celestial overlay, remote control, scheduled capture, the intervalometer, interim saves and anamorphic desqueeze. They are marked PRO in the app. Entitlements are checked on device, so PRO keeps working where there is no signal. TWO APPS, ONE CAMERA • Even Longer — this app: the camera, paid, with the optional PRO upgrade. • Even Longer Remote — the controller for iPhone, iPad and Mac. It needs an Even Longer camera with remote control (PRO) switched on. Built for photographers who plan the shot — and want the file to be worth the wait.
