Pinhole Master is a light meter and exposure timer for pinhole photographers, or anybody else photographing with long exposures. Use your iPhone/iPad camera to determine the light level (Exposure Value). Tap on the preview display to localise a reading then fine tune the result with the slider. Alternatively insert a Lumu device for incident light measurement or enter an EV measurement manually.
Maintain a library of cameras you own and films/papers you use, together with optional fully customisable reciprocity failure compensation. Tap to Hold a light reading for when you're ready to make the exposure, if desired. Then tap on Start Timer at the same time as you begin your exposure. A record of all settings used along with the preview image is automatically written to a Log for future reference.
Supports apertures from f/1 to f/999, Exposure Index (ISO) from 1 to 9999, (optional) filters up to 10 stops
Fast and accurate EV readings displayed to one decimal place or thirds (computed as 64-bit internally)
Calibrate your device camera sensitivity in Settings with minimum and maximum EV levels to avoid bogus readings, especially in low light
Preview overlays of the EV level and camera/film parameters (which can be turned off in Settings)
Film/paper-specific reciprocity failure compensation from your own testing, manufacturer specifications or measurements you've found on the web
Sophisticated smoothed interpolation used in determining the compensated exposure time
Coordinates of your capture written to the log, along with a map of the location
Judicious use of GPS to conserve battery life
A modern user interface designed for efficient use in the field
Support for the original Lumu (now Lumu Lite, see www.lu.mu) for precise incident light measurement
