Our group of photographers met up on Saturday in time to cover the 'so-called' Blue Hour when it is possible to balance the light in the sky with any artificial lighting. On a sunny day, it happens when the sun's elevation is between -4 degrees and -6 degrees, just below the horizon line either before sunrise or just after sunset, ranging between 20 and 40 minutes, depending on the weather. Here are my series of images taken between 16.15 and 17.15 on an overcast day.
