Frame it for your camera. Meter it for your intention. Choose your camera format and focal length, then highlight what matters with Custom metering. Evlume is a reflected-light meter for photographers who want to decide what matters in the frame. FRAME FOR YOUR EQUIPMENT Choose your camera format and focal length to preview the corresponding field of view. Meter the framed area as you plan your photograph. HIGHLIGHT WHAT MATTERS In Custom mode, use your finger to highlight the areas you want included in the reading. A yellow mask shows your selection. Choose a finer or broader highlighter, clear the selection and start again, or save a frequently used mask as a preset. FOUR METERING MODES • Spot: measure a selected area. • Weighted: place greater emphasis toward the center. • AVG: meter across the frame. • Custom: highlight the areas that matter to your photograph. EXPOSURE CONTROLS Set your ISO and work in aperture-priority or shutter-priority mode. Take a reading to calculate the corresponding exposure setting. Adjust exposure compensation, dial increments and calibration to suit your workflow. MADE FOR USE IN THE FIELD Tactile dial controls, visible metering masks, Quick Start guidance and a searchable manual help you find your way around. No app account is required, and light measurement is processed on your device. Evlume measures reflected light using your iPhone camera. Results depend on the scene, device and calibration. Use your photographic judgment when choosing exposure for your subject and medium.
