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.
