Designed by a photographer, for photographers. Built with a single goal: reliable and precise exposure, for both digital and analog workflows. Whether you’re shooting film or digital, this app gives you full control over exposure with a clean, professional toolset. Key Features . Extended sensitivity down to -2.5 EV (perfect for low-light scenes) . Incident and reflected metering . Two interface styles to match your workflow . Point metering directly from the camera view . Full manual control: aperture, shutter speed, ISO and exposure compensation (1/3 steps) . Range: from 4 hours to 1/8000s, aperture f/1.0 to f/512, ISO 0.8 to 6400 . Aperture priority (Av) and shutter priority (Tv) . Auto ISO or locked ISO . Save and review exposure data . Extract exposure data from photos in your gallery . Average multiple measurements for higher accuracy Advanced Tools . Hyperfocal distance calculator (supports 5 lenses) . Lens memory: aperture, focal length and sensor/film size . Infrared hyperfocal support (IR mode) . Maximum aperture limit based on selected lens . EV display (analog scale or numeric) . f/Tools integration Important For accurate incident metering, a diffuser must be placed over the front camera. Without it, readings will behave as reflected light metering. About This app is built and maintained by an independent photographer and developer. This is the tool I personally use and continuously refine. If you have suggestions or need help, feel free to contact me:
