The blue hour is an important time of day for photographers. It is a period of twilight in the morning and in the evening when the sun is at a significant depth below the horizon and when the residual, indirect sunlight takes on a predominantly blue shade. On a clear day, blue hour can be a colorful spectacle, with the indirect sunlight tinting the sky yellow, orange, red, and blue.
That is why it suited me very well that an hour of rest was built into the program of the project meeting one hour before sunset last Monday in Alkmaar. It was a very cold day with a strong eastern wind and almost 8 degrees below zero but the result counts.
