## What is Kelvin?

Kelvin reads your camera's white balance sensor to measure color temperature in real time — no gray cards, no guesswork.

Unlike apps that sample pixels from a photo, Kelvin taps into your device's auto white balance hardware for fast, accurate CCT readings from 2000K to 10000K.

PRO FEATURES
- Gel Calculator — instantly find the right CTO/CTB gel to shift between any two color temperatures
- Color History — log and compare readings across locations
- White Balance Lock — freeze the sensor for consistent measurement

BUILT FOR SET
Designed for gaffers, DPs, and photographers who need to match light sources without carrying a dedicated meter. Reads the sensor, not the screen.
