How to use:
1. Download and open Photometer, then allow camera access for metering accuracy.
2. Optionally set your preferred units (EV or lux), choose Photo or Video mode, and add a camera preset for consistent results.
3. Point the camera at your subject, select spot or average metering, and read the suggested ISO, aperture, and shutter values in real time.
4. Lock a reading to hold exposure, then apply the recommended settings on your camera; for video, set frame rate and shutter angle to get the correct shutter speed.
5. Add ND filters or adjust ISO to see automatic compensation, use the histogram to avoid clipping, and save presets for quick reuse on future shoots.
