An ink tree maybe? This is water soluble suminagashi ink in water. I use this ink because of the very reason these images sometimes get constructive criticism about focus. That is that the ink is dissolving rapidly into the water and therefore has a soft, ephemeral and surreal look. The inks are dropped in at different rates and through an oil barrier which provides some control. Then I flip the final image to be 'trees'. Enjoy!
