Light Meter helps you measure exposure in real time and find the right camera settings faster. Designed for photographers and filmmakers, the app turns your iPhone into a practical exposure meter for everyday shoots, studio work, portraits, landscapes, and low-light scenes. Quickly read the light in front of you, lock the settings you want to keep fixed, and let the app calculate the missing exposure value automatically. Whether you are shooting with a digital camera, film camera, cinema camera, or manual lens, Light Meter helps you work with more confidence before you press the shutter. โ€ข Live Exposure Reading Measure light in real time and instantly calculate camera-ready exposure settings. โ€ข Lock Any Two Controls Choose which two settings stay fixed - ISO, shutter speed, or aperture - and let the meter calculate the third automatically. โ€ข Shutter Priority Freeze motion or create blur while the app calculates the right aperture. โ€ข Aperture Priority Set your depth of field and let the meter solve the matching shutter speed. โ€ข Auto ISO Keep shutter speed and aperture fixed while the meter adjusts ISO automatically. โ€ข Spot Metering Tap the preview to meter a specific part of the scene with more precision. โ€ข Built for Real Shoots Use it for portraits, landscapes, studio lighting, street photography, film photography, and video exposure planning. Light Meter gives you a fast, visual way to understand exposure before shooting. It is especially useful when working with manual cameras, adapting to changing light, checking mixed scenes, or planning a consistent exposure setup. Simple enough for beginners, precise enough for advanced photographers. Terms of Use: https://www.optionalchaining.com/terms-of-use Privacy Policy: https://www.optionalchaining.com/privacy-policy
