With the use food dye, a vase of water, and a macro extension tubes, I was able to snap these cool ink swirls. The process is simple, I used speed flash, remote trigger water, food dye of various colors and my Nikon D5100 camera. You have to set your camera setting to manual and focus in manual. My camera setting for almost all of these shots were 1/200 shutter speed, f/10 ISO 100 with the flash setting for the white balance.
