I wanted to create an image that had multiple layers to it but did not want to use Photoshop to make the layers. This is an image of a drop of oil on a glass panel with a colorful scarf below and out of focus. the black swirls are from a drop of ink added to the oil drop. Captured with a Nikon D800e and Nikor 105 mm macro lens on a Gitzo ball head and Manfroto tripod. The camera was fired using a Nikon Cable release and the flash is off camera SB-800 on the ground lighting the scarf.
