NightRelight

Bad light should not erase a good night. NightRelight is a focused iPhone app for underexposed night photos. Choose a dark photo, let the bundled on-device model correct the lighting, compare the result with the original, and save only when you are satisfied. ON-DEVICE BY DESIGN Photo relighting runs locally on your iPhone with Apple Core ML. NightRelight does not upload your photos to a NightRelight server and does not need a cloud model for processing. FREE MEANS FREE There is no subscription, in-app purchase, paywall, advertising, or paid cloud inference. BUILT FOR NIGHT PHOTOS NightRelight is designed for dim and nighttime scenes where the main subject is underexposed but still visible. It is not a face generator, identity replacement tool, beauty filter, or general daylight editor. PICK, RELIGHT, COMPARE, SAVE • Select a photo with Apple's system photo picker • Process it locally on your iPhone • Compare before and after • Adjust the strength • Save a copy to Photos • Process several photos in a batch • Find dark portraits from a selected month, scanning up to 400 photos locally • Keep a local rescue history and local diagnostics PRIVATE BY DEFAULT Your selected photos, saved rescues, and processing details stay on your device. NightRelight does not require or offer an account. It has no account server and does not sync photo or history data between devices. NightRelight is designed to improve visible lighting, not to reconstruct missing detail. Model-based processing and noise reduction may alter fine details, especially at high strength. Always compare with the original before saving. Results vary by image and device.
