MeterGlass is a professional light meter for film and digital photographers. • Average and spot metering: wide-angle averaging or a ~1.5° reflected spot — pinch to zoom in to ~1°, with a live acceptance-angle readout. • Zone System: sample multiple points to see scene contrast, shadow/highlight placement, and N± development suggestions. • Metering calibration: align it to a meter you trust or a gray card for dependable readings. • Full exposure info: EV, aperture/shutter pairs, exposure compensation, illuminance (lux), and color temperature. • Instrument-style UI: compact viewfinder with large, clear readouts, AE-L exposure lock, and single-shot or continuous metering.
