KelvinCam — a real light meter in your pocket

Point your iPhone at any scene and instantly read color temperature, tint, and exposure value. Get shutter speed, ISO, and white balance recommendations for photo and video — all calculated live on your device.

Color & Exposure

Live Kelvin readout, green‑magenta tint, and EV100 with human‑readable light level labels from Candlelight to Full Sun.

Photo & Video Modes

Eight scene presets for photo. The 180° shutter rule applied automatically for video, with ND filter recommendations when you need them.

Lock & Solve

Lock shutter or ISO and let KelvinCam solve for the other value in real time — like semi‑auto mode for any camera.

Snapshot History

Save full readings with timestamps and notes. Log setups, annotate locations, and share as formatted text.

Privacy first. KelvinCam processes everything on‑device. No images, video, or sensor data are ever stored, transmitted, or shared.
