Luma : AI White Balance Meter

Turn your iPhone into a pro cinematic light meter! Get pinpoint Kelvin, CC/MG Tint & PDF reports using AI, LiDAR & Apple Watch telemetry. Perfect your white balance now.

Luma is the ultimate professional AI White Balance, Color Temperature, and CCT Light Meter. Turn your iPhone, iPad, and Apple Watch into a cinematic spectrometer for precise lighting data.

Ditch the bulky hardware. Whether you are a cinematographer matching multiple cameras on a film set, a gaffer dialing in practical LEDs, or a photographer hunting for the perfect skin tones, Luma gives you exact Kelvin and Tint readings in seconds.

Luma taps directly into your device's image signal processor, bypassing standard auto-white-balance algorithms to deliver a true assessment of ambient light, mixed practicals, and complex studio setups.

CINEMATIC LIGHT METERING & CCT ANALYSIS Stop guessing your white balance. Luma provides real-time, ultra-accurate telemetry to ensure your shots are perfectly balanced.

Real-Time CCT & Tint: Get instantaneous Color Temperature readings in exact Kelvin alongside highly precise Tint data.

Gaffer-Friendly Formats: Toggle your Tint display between standard Decimals (+0.00) or professional Gaffer CC/MG units (e.g., 2M, 3G) to quickly select the exact CTO or CTB lighting gels you need.

Dual Metering Modes: Use Matrix mode to read the overall ambient scene, or switch to Spot Metering with up to 5x digital zoom to isolate specific light sources or a subject's face.

Anti-Flicker Technology: Eliminate LED banding with hardware-level 50Hz and 60Hz shutter synchronization.

PERFECT CAMERA MATCHING & SYNC

Match WB Mode: Lock a reference reading from your primary setup, then move your camera to your secondary setup. Luma instantly calculates the exact Kelvin shift needed to match them perfectly, saving you hours of color grading.

Manual Compensation: Use the digital slider to dial in deliberate warm or cool biases (from -2000K to +2000K) to maintain a specific creative look across different locations.

ADVANCED AI & LiDAR SENSORS

AI Face Focus: Luma’s Vision AI automatically detects and tracks human subjects in the frame, prioritizing natural, accurate skin tones regardless of mixed background lighting.

LiDAR Depth Isolation: Map planes in 3D space using your hardware LiDAR scanner. Isolate foreground subjects from the background with a cinematic False Color peaking overlay.

Grey Card Smart Scan: Point your camera at a physical 18% grey card. Luma will instantly scan it and perfectly align the sensor to your scene’s true white point.

D65 Screen Match: Tap the D65 Align button to instantly sync the sensor to a 6500K baseline, ideal for matching Mac XDR displays and calibrated monitors.

PRO LOGBOOK & PDF EXPORTS

Luma's Logbook is the ultimate continuity tool for script supervisors and DPs.

Evidence Snapshots: Capture high-resolution photos stamped with exact Kelvin, Tint, the AI mode used, and specific device hardware models.

GPS Location Tagging: Automatically attach precise coordinates to your logs for seamless location scouting.

Production Notes: Add custom setup names and detailed text notes to any saved reading.

Studio Reports: Export gorgeous PDF cinematic lighting reports or bulk CSV data sheets. Add your custom studio branding to the footer before handing the data off to post-production colorists.

APPLE WATCH COMPANION APP

Live Wrist Telemetry: Mount your iPhone on a C-stand and beam live Kelvin and Tint data directly to your wrist.

Remote Capture Trigger: Trigger a full-resolution log save from your Watch with a single tap.
