Colours in your scene change throughout the day with the position of the sun
During sunrise and sunset, the light is warm and soft. colours will take on a warmer cast, with orange and red tones becoming more prevalent.
During the middle of the day, colours can appear washed out and harsh, thanks to the bright sunlight falling on them. A polarising filter will help to add punch and saturation.
twilight occurs twice a day, at dawn and dusk. colours are more subtle and subdued, as the earth’s upper atmosphere scatters and reflects sunlight to illuminate the lower atmosphere.
