• Enter the aperture and time from your external light meter
• Converts the reading to your pinhole’s aperture, then applies reciprocity to the converted time
• Manufacturer-published data for popular black and white films, with the source shown in the app
• Add your own film or paper, including paper negatives, with your own reciprocity exponent
