Understand the light

Dusk and last light

Dusk is the fading light after sunset, as the Sun sinks further below the horizon. Last light, or civil dusk, is the moment the Sun reaches 6 degrees below the horizon and usable daylight is gone; after that the sky darkens through nautical and astronomical dusk into full night.

Last light, civil dusk and the three dusks

Dusk mirrors dawn in reverse. Civil dusk, at 6 degrees below the horizon, is last light: the end of comfortable outdoor light. Nautical dusk follows at 12 degrees, when the sea horizon disappears, and astronomical dusk at 18 degrees, after which the sky is fully dark and the faintest stars appear.

How long dusk lasts depends on where you are. Near the equator the Sun drops steeply and night falls fast; at high latitudes dusk can stretch for hours, and in high summer it may never fully darken.

Dusk is not the same as sunset

Sunset is the instant the Sun's upper edge slips below the horizon. Dusk is the fading twilight that follows. For blue-hour photography or a last look before dark, dusk is the window that matters.
