Month: February 2020

Call sheets often list First Light/Dawn, Sunrise, Sunset and Dusk/Last Light times.

Best practice is to calculate them for your shooting location. I’ve provided Sydney for March 2020 below.

SYDNEY Lat=-33°52’00” Long=+151°12’00”
TIMES OF SUNRISE AND SUNSET (for ideal horizon & meteorological conditions)

AT Astronomic Twilight = Centre mass of Sun is 18° below the horizon. Light pollution prevents astronomy.
NT Nautical Twilight = Centre mass of Sun is 12° below the horizon. Horizon can normally be distinguished.
CT Civil Twilight = Centre mass of Sun is 6° below the horizon. Normally enough light to see without artificial light.
Transit Time when Sun is highest in the sky.
