With Pinhole Assist, you can : • Compute exposure time ; • Mesure light; • Locate your camera in the predefined list or compute its aperture; • Let the assistant automatically compensate for reciprocity of film (correction for long exposures), or use your own curves. Here is the main screen. You measure light directly. Estimate light or measure it directly with the camera (all EV used refers to 100 ASA) You can also use an external light meter with the manual EV scale.
