Tiny Tuesday: Tiny Bubbles

I had fun taking this macro shot. It's of some of the bubbles inside a little glass marble - even the biggest bubble can't be more than 0.5mm across.

(I'm not sure whether it should really be in Tiny Tuesday or Abstract Thursday! - I guess it could fit for either.)

The photo isn't cropped at all - I got really close with the camera, using 26mm of extension tubes along with an extra 20 dioptre lens stuck onto the front of the 60mm macro lens. It's fun to experiment!

The orange background colour is from the coloured swirl inside the marble.

Many thanks to dbifulco for hosting TT this month.
