Teeny tiny

This week’s Photo Challenge is called What is it?. The idea is to take an extreme close up of something, so it’s hard to tell what it is.

I’m still getting to grips with my new Canon 450D, but I bought a set of macro extension tubes and I’ve been experimenting.

I may or may not enter one of these, or another one, into the Challenge itself. So I’m not going to say what these are 😛
