Evios is a professional-grade reflected-light meter that provides precise exposure readings normalized to EV100.
Designed for photographers who need a dependable reference for manual film or digital cameras, Evios offers full transparency into your device's auto-exposure data.
Key Features:
Live & Manual Modes: Meter automatically using your camera sensor or input EV values manually for "what-if" scenarios.
Standardized EV100: View brightness as a single, standardized exposure value (EV) normalized to ISO 100.
Advanced Transparency: The Advanced panel reveals live shutter speed, aperture, and ISO reported by the camera, showing exactly how the EV is derived.
Minimalist Design: A high-contrast, distraction-free interface built for quick adjustments in any lighting condition.
How to Use:
Point the camera at your subject to fill the frame.
Adjust the ISO and Aperture sliders to find your desired settings.
Evios calculates the perfect shutter speed instantly.
Privacy First: Evios uses the camera strictly to measure ambient light. No photos or videos are ever captured, stored, or transmitted.
