Widely considered the most beautiful times of day, sunset and sunrise are also probably the most difficult to photograph

Capturing the right composition of light and camera settings while racing against the movements of the sun can be an unforgiving enterprise, but, if you get it right, the results are often spectacular.

Fifty stunning sunset and sunrise-themed photos – selected from nearly 20,000 submissions – are now vying for victory in #GoldenHour2020, an international competition put on by free-to-use photography app Agora.
