Camera Light Meter

Glowdex is a precise, intuitive light meter designed for photographers.

Measure reflected or incident light, calculate exposure combinations, and quickly find suitable aperture and shutter speed settings for your selected ISO and stop increment.

With AI Analysis, Glowdex turns measurement data into clear, practical guidance:

In Reflected Light mode, AI considers both the measured values and the captured scene.
In Incident Light mode, AI analyzes readings collected through the diffuser—no scene image is sent.
Each report provides a concise summary and subjective optimization suggestions that account for real-world lighting, subject tone, dynamic range, and creative intent.
Measurements provide a reliable baseline. Glowdex helps you interpret that baseline and adapt it to the photograph you want to create.
