This is the second project that I worked on this year.  I initially started with water and food coloring, but didn't like the results.  I wanted something a little bit more dramatic so I wasted the last 1/4 of my girlfriends milk.  She wasn't too happy about that. Haha. The white of the milk and the red food coloring gave the photo a nice pop.  I was shooting at 125mm zoom - 100 ISO - f stop at f5.0 - shutter speed 1/200.  Remote flash set at 1/8.
