A rainy night I wondered that if the rain can be at different forms which we can not see with our eyes. So I took my camera and started to shots behind the window glasses. The light source was night lamps at the garden and on the street. First I was trying long exposure then I started to shake the camera up and down and left and right at the same time. When I finished it I opened them via photoshop and turn to b&w. There it was! Rain drops was completely in different forms.
