For the Blandia water theme competition I took lots of different kind of images just to try out stuff (see here for my official submissions
). Above you see one of the experiments. It fairly simple: a water stream from the water tap falling down into a black colored sink filled with water. Now days a tap mixes the water with air resulting into a nice and airy stream. When taking a snapshot you clearly see the air bubbles in the stream.
TECH-INFO: behind the sink I placed white cardboard and lit it with two speedlight flashes from both sides of the camera. The short pulse of the flash (less than 1/1000s) freezes the fast motion of the stream. During RAW conversion I worked on getting maximum detail. In Photoshop continued that process using masked adjustment layers of the curves tool. In the original image there was almost no color so at the end I added a deep blue filter to tone it a tiny bit. The image is also slightly cropped.
