Scrim: Light Meter & Level

Check clipped highlights and horizon tilt before taking a photo. Scrim turns the live camera preview and motion measurements into a clear framing guide, including when a reading is uncertain. FRAME: See a framing recommendation, horizon angle and clipped-highlight proportion. LIGHT: Explore the brightness range visible in the preview and its measurement limits. VERTICALS: Estimate perspective convergence after selecting your lens’s half vertical field of view. DELIVERY: Compare HDR headroom using a gain ratio you enter and example display assumptions. This is a manual planning tool; it does not import or analyse photo files. The paired Apple Watch displays the iPhone’s current framing decision. Keep Scrim open on the iPhone for live measurements. Scrim is a guide, not a camera or a calibrated lux meter. It does not take photos or determine exposure settings. Results depend on the camera preview and device motion. No account or subscription. One purchase. Camera frames are processed on your device and never saved. Measurement results and framing guidance can be sent to your paired Apple Watch. For iPhone, iPad and paired Apple Watch. Available in English, German, Spanish, French, Japanese and Turkish.
