Summer solstice bars

Each vertical line is the average of a frame from this Helsinki summer solstice timelapse video, the first midnight on the left, noon in the middle, and the final midnight on the right.

 

The wide bands of colour represent the different directions the webcam points to during the day, but you can still see the change in daylight.
