Available light photography exposure calculator

Enter a film speed (or digital equivalent) and ambient lighting conditions. We will give you a table of apertures (f/stop) and shutter speed for the given exposure value (EV). This table allows you to use a camera with manual control in conditions outside the range of the built-in light meter, which is common in available light photography. The table does not account for reciprocity failure which reduces the sensitivity of film for very long exposures (this does not apply to digital sensors).
