The light at the beginning and end of the day can be very similar, with the low sun casting long shadows and revealing form and texture in the landscape and warm colours. There are slight differences in the light and colour, however. With cleaner air at sunrise, colour is less diffused and can be more intense than at the other end of the day. At sunset, the colour can be less vivd but there are more particles in the atmosphere, which can scatter the light across a larger part of the sky, rather than being focused around the sun.One weather condition to look out for at sunrise is mist. Although thick fog will kill off any hope of early colour, a low-lying ground mist can really enhance a sunrise, hiding clutter and simplifying the landscape below, as well as adding tonal contrast to the scene.
