## Light Meter LuMe Description
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).

### ***** "The best light meter app"
I love how quick and easy it is to spot and zone meter. For spot I can add points instantly by tapping around the screen and then lock the positioning, and for zone I can move the shadow, mid, and high points step by step to see the effect on the final photo. I’ve never been able to do complex metering this fast before, but matrix and center metering still stays simple to use and read.
-- cfanaic, 2026-05-30

### ***** "Best In Class"
