Store description excerpt
Match light to your camera before you roll. Kelvy turns your iPhone or iPad into a practical white balance meter for filmmaking, photography, lighting setups, and location scouting. Measure Kelvin and green/magenta tint, identify likely light sources, and get settings tailored to your camera—not just a generic number. CAMERA-READY GUIDANCE Choose a profile for ARRI, Blackmagic Design, Canon, DJI, Fujifilm, GoPro, Nikon, OM System, Panasonic, RED, Sony, or Generic. Kelvy rounds each reading to the Kelvin and tint increments your camera supports, helping you move from measurement to setup quickly. WHAT KELVY SHOWS • Estimated Kelvin color temperature • Green/magenta tint shift • Camera-specific white balance and tint settings • Likely light-source category • CTO/CTB gel suggestions for balancing mixed lighting • A live color-temperature graph BUILT FOR THE WAY YOU WORK • Capture and save readings with thumbnails and location details • Export branded photos with measurement overlays • Copy Kelvin values with one tap • Apply an offset to match a trusted meter or camera body • Choose to open Kelvy directly to the Light Meter FREE TO USE Kelvy includes 5 captures every week at no cost. Kelvy Pro unlocks unlimited captures. Measurements are camera-based estimates and may vary by device, reference surface, exposure, and mixed lighting. For best results, aim at a neutral white or gray reference under the light you want to measure. For critical color work, compare with a calibrated meter.
