Taken for the "Full sprut/splash" challenge in Twitter Photo challenge Group.
EF-530 DG Super shoe cord OC-E3 cam left with DIY softbox. A reflecting surface (aluminum foil) on the right.
I used a black book as background (not quite) at a splash-safe distance.
I dropped ice cubes into the water, because I wanted to avoid the (even more) traditional piece of bright colored fruit. The ice cube (in the bottom) was removed with an overlaying image of the glass without the splash.
