Filling the Frame

Our Photo Soc set this week's theme as 'Filling the Frame'.

Taking that literally, led me to come up with this idea.  Really, it is just proof of concept as I don't own some of the specialist gear that would give me better quality - no off-camera flash, no studio lamps and no fish tank.
I had to improvise with an empty coffee jar, jug of water and a piece of black card. Natural light came from behind and a window at the side, colour was added on the computer.
