I had been photographing seascapes in the evening using relatively long exposures in order to capture movement in the sea. When removing the camera from the tripod, I accidentally triggered the shutter while a flock of birds were taking off from the rocks.
The slow shutter speed, combined with the movement of the birds and also the camera has created an ethereal image where the birds looks almost like angels or ghosts rising into the air.
