Light Meter - Lite

Light Meter - Lite transforms your smartphone into a precision spot meter for film and digital photography, trusted by over 400,000 photographers worldwide.

Whether you're shooting film SLR, medium format, large format, or digital mirrorless, accurate exposure metering is fundamental to capturing perfect shots. This app delivers professional-grade metering tools without the need for expensive dedicated hardware. Tap to focus exposure points, compare multiple readings across your scene, and understand your dynamic range instantly. The Zone System metering feature lets you assign zones (0–X) to readings and see exactly how each area will render in grayscale, eliminating guesswork in high-contrast situations.

Beyond spot metering, Light Meter - Lite includes an incident light meter powered by your device sensor, plus exposure preview with compensation and neutral density offset calculations. Volume button controls let you start and stop metering without touching the screen, while live histogram display gives you real-time feedback. Use the exposure timer for long exposures, and switch between foot-candles and lux measurements. The app is calibrated against professional Gossen and Sekonic meters, ensuring your readings are accurate every time you shoot.

Your complete photography toolkit includes 12 specialized calculators: depth of field with hyperfocal distance, reciprocity tables for 40+ film stocks (Portra, Tri-X, HP5, CineStill, and more), exposure bracketing with custom step increments, pinhole camera effective f-stops, white balance correction, bellows factor for macro work, flash guide numbers, EXIF reader, angle of view, and the classic Sunny 16 rule. Cinematographers benefit from shutter angle mode for frame-rate-based calculations.

Customize your workflow with half-stop and third-stop increments, define your own ISO and shutter speed ranges, and create hardware profiles for different camera systems. The golden hour and blue hour calculator helps you plan shoots around optimal lighting conditions with sunrise, sunset, and twilight time alerts.

Organize your work by logging exposures with GPS coordinates and notes, then export and reference past readings to refine your technique. The entire app works offline—no internet connection required for metering or calculations. With support for 50+ languages, Light Meter - Lite adapts to your needs whether you're on location or in the studio.
