Understanding sunlight
A little light on
the details.
The Sun does not simply switch on and off. Its angle below the horizon creates distinct phases of light, each useful in its own way.
Golden hour
Soft, warm light while the Sun is close to the horizon—often favored for photography.
Civil twilight
Enough natural light for most outdoor activity before sunrise and after sunset.
Nautical twilight
The horizon remains visible at sea while brighter stars begin to appear.
