  • To display the suggested time exposure for one of the solar eclipse events, select the event, the sensitivity (ISO) and the lens aperture (f/number). The altitude of the Sun and elevation of the observer do have a measurable influence on the exposure time, just as the sky conditions. The time exposure will then be displayed and computed every time you modify one of those parameters.
  • The time exposures are only given as a guide. They will help you choosing a film matching your equipment and the event you are shooting. An automatic sequence can also be build accordingly. However, on the day of the eclipse, you should bracket your exposures one or more stops (±1EV or more) to take into account the actual sky conditions and the variable nature of these phenomena. If the sky is not clear or hazy, then lengthen the exposures.
