Camerae vs Long Exposure

Camerae is a capture tool for documenting change, repeating photographic compositions, and revealing details of the night sky. With two specialized workflows — Repeatable and Astro — the app helps you plan, capture, compare, align, and export images while keeping you in control. REPEATABLE Document the same place over hours, days, months, or years. Use a reference image, composition grids, and device sensors to return to the original framing with greater precision. Create photo sequences, timelapses, or videos to follow construction, landscapes, growth, seasonal changes, and creative projects. ASTRO Plan and capture night-sky sequences with controls designed for astrophotography. Organize frames and process results directly on your device. CAPTURE AND ALIGNMENT • Reference image for repeating a composition • Photography grids and visual alignment tools • Orientation and positioning indicators • Camera and exposure controls • Portrait and landscape capture • Translation, rotation, and scale alignment • On-device processing and timelapse creation • Video playback and sharing PRIVACY BY DEFAULT Your projects, photos, videos, and capture information stay on your device. Camerae has no accounts, advertising, or tracking. Content leaves your device only when you choose to export or share it. Capture time. Return to the same composition. Reveal what the eye cannot see.

Long exposure photography, without the guesswork. An iPhone shutter physically cannot stay open for thirty seconds. So this app does what a long exposure actually is: it stacks hundreds of live frames on the GPU and blends them in linear light, the way the physics wants it done. The result is a real long exposure — and you watch it form on screen while it happens. THREE WAYS TO STACK Motion Blur — averages every frame into smooth, flowing movement. Waterfalls turn to mist. Clouds smear across the sky. Crowds become ghosts. Light Trail — keeps the brightest pixel from each frame. Headlights draw ribbons through traffic, sparklers write in the air, stars arc across the night sky. Low Light — adds frames together to gather light a single shot could never collect. The more frames land, the further noise falls away, and dark scenes come back clean instead of grainy. STOP WHEN IT LOOKS RIGHT Most long exposure tools ask you to commit to a duration up front, then leave you waiting blind. Here the exposure builds live in front of you. Watch the trails grow, watch the water go silky, and end the shot the moment it looks right. Not there yet? Pick the exposure back up and keep stacking from exactly where you left off. Nothing is thrown away until you say so. TOOLS THAT TELL YOU THE TRUTH • Live histogram that updates as the exposure builds • Zebra clipping warning marks blown highlights before you lose them • Running frame count and total exposure time, always on screen • Review the finished frame full size before anything is saved SEVEN SCENE PRESETS Waterfall, Traffic, Star Trails, Fireworks, Light Painting, Night Scene, and Empty the Street — the last one averages a busy scene until the people walking through it simply disappear, leaving the street to itself. Every preset is a starting point, not a cage. Adjust anything after loading one. MANUAL CONTROL WHEN YOU WANT IT • Lock exposure, white balance and focus so brightness and color never drift mid-stack • Manual ISO, or let the app work it out from the scene • Set exposure length, or hold the shutter open and decide by eye • 3 and 10 second self-timer for tripod work BUILT PROPERLY • 16-bit float accumulation, so nothing bands or clips partway through the stack • sRGB is linearized before blending and re-encoded afterwards — highlights stay honest instead of turning to grey mush • Saved to your photo library as HEIC with real EXIF: total exposure time, ISO, capture mode, and the exact number of frames stacked • Full resolution. No watermark. No account. • iPhone and iPad WHAT IT IS GOOD AT Silky waterfalls and coastlines. Car light trails on a night road. Star trails and the Milky Way. Fireworks caught as complete bursts instead of fragments. Writing in the air with a torch. City streets after dark, without pushing ISO until the noise eats the shot. Clearing tourists out of a landmark photo. A tripod or a steady surface will always give you the cleanest result — that is true of every long exposure ever taken, on any camera.
