These images are created by manually dropping cream or water, coloured with food dye, into a small aquarium filled with water. The images are then rotated 180 degrees . Some are altered using the mirror and flip technique. In 2013 I completed "The Ultimate Guide to Water Drop Photography" Ebook. It is quite descriptive and explains this technique in detail.
