Both dawn and dusk are ideal moments to shoot photographs. Light is soft and it doesn't generate so much contrast. They also have that orange tone which makes any photograph look incredible.
Both moments in time are called "golden hour" by photographers. Light conditions are almost perfect for any type of photograph. Generally, the ‘’golden hour’’ is consider to be the first and last hour in which there is sunlight. It won't be exactly 1 hour because this will vary depending on the season of the year and the location on the globe.
This photograph was taken at dusk, facing the sun. The photograph has a warm colour which makes the landscape more interesting than it really was. Actually, being honest, the star of this photograph is light itself.
At dusk and dawn, the sun is below the horizon. This means we can control the direction of light from where the object/subject is being illuminated. In simpler words: if we are shooting photographs of a person, we can place this person in front of the sun, giving his/her back to the sun or sideways. Basically, we can change the direction in which light reaches the subject. To achieve this, we need to move the subject until we find the illumination we want.
Every photograph will be different and it will have a different sensation or mood. It is us, the photographers, who need to decide how to position the subject in relation to the light.
