Just a drop
This was 3 images stacked in PS to get the water drop really sharp. I know the composition isn't great with the drop being central but I am still happy with the result considering its my first photo stacking attempt. When I said water drop its actually Eye Drops bought from Boots (chemist) as I heard that it beads better (although it took several attempts as it kept rolling off). The light was all natural with a homemade reflector (aluminium foil) and a house plant was placed in the background to give it a more natural look.
