Light Meter LuMe vs Meter One

LuMe is a pro-grade light meter and exposure calculator built for film photographers. Whether you're shooting medium format on a Mamiya, large format on a 4×5, or 35mm on a Leica, LuMe gives you the exposure intelligence your film camera doesn't have. METERING MODES FOR EVERY SITUATION • Matrix — averages the whole scene for balanced exposures • Center-weighted — emphasizes the middle, like a classic SLR meter • Spot — measures a small area you tap, just like a 1° spot meter • Zone System — Ansel Adams' tonal mapping (Zones I–IX) right in your viewfinder MULTI-POINT SPOT METERING Place up to four spot markers anywhere on your scene. Read each EV at a glance, evaluate contrast range, and place tones with intention. LIDAR SPOT DISTANCE (on Pro devices) See the physical distance to any metered spot — useful for hyperfocal setup and verifying focus on rangefinders and manual-focus lenses. RECIPROCITY CORRECTION FOR EVERY FILM STOCK Long exposures don't behave linearly on film. LuMe applies the Schwarzschild exponent for your stock — Tri-X, TMax, Portra, Ektar, Velvia, and more — so you don't need printed tables in your bag. DEPTH OF FIELD CALCULATOR Hyperfocal distance, near limit, far limit — for 35mm, APS-C, medium format (6×4.5, 6×6, 6×7), and large format (4×5). One tap. FLASH GUIDE NUMBER CALCULATOR GN, distance, power fraction → f-stop. Solved. LIVE EXPOSURE TOOLS • Histogram overlay • Highlight/shadow clipping warnings • ND filter compensation • Aperture priority & shutter priority • Exposure compensation dial • ISO and shutter range constraints (cap at your film speed) BUILT FOR THE WAY FILM PHOTOGRAPHERS ACTUALLY SHOOT • Spot meter a high-contrast scene; place highlights on Zone VII • Apply reciprocity for a 30-second exposure on Tri-X • Calculate hyperfocal for landscape work on Portra 400 • Verify a flash setup before burning a frame LuMe replaces your handheld meter, reciprocity card, DoF chart, and flash calculator with one tool that fits in your camera bag. Available in 16 languages: English, German, French, Spanish, Italian, Portuguese, Dutch, Swedish, Polish, Turkish, Russian, Arabic, Japanese, Korean, Chinese (Simplified & Traditional).

Meter One is a reflected light meter for film photographers. Point your iPhone at the scene. Meter One reads the light and gives you practical exposure settings: shutter speed, aperture, ISO and exposure compensation. It is built for real analog gear. Manual cameras. Vintage lenses. Medium-format systems. Bodies with missing, broken or unreliable meters. Meter One does not work like a generic exposure calculator. It lets you define the limits of your camera and lens, so the recommendations match the gear you actually use. Features: • Live reflected-light metering with the iPhone camera • Aperture Priority, Shutter Priority and Manual modes • ISO and exposure compensation controls • Recommended shutter speed and aperture • Camera body shutter-speed limits • Lens aperture limits • Hold reading control • Analog-style exposure dial • Saved readings and film roll log • Calibration tools • On-device metering Use Meter One with manual 35mm cameras, medium-format cameras, vintage SLRs, rangefinders and classic systems with limited shutter speeds. Meter One Pro is a one-time lifetime unlock. It includes unlimited gear profiles, saved readings, calibration tools and future film workflow features. Privacy: Meter One uses the camera preview for live metering. It does not need to save photos for exposure measurement, and camera frames are not uploaded. No ads. No account. No tracking. Meter One is a practical reflected-meter aid for film photography. Readings can vary with scene contrast, lighting conditions, camera behavior and device characteristics.
