Lichen

I thought I'd try a macro but rather than showing the first practical application in the shape of proving the nature of the deckchair assembly failure I thought I'd post some lichen on the birch tree. I think I probably won't be using this for macros because I have better possibilities with the 7d in general.

It's a bit too hot to think and I have to at the moment. This posting is late because I tried to post it in the future. I'm not exactly sure how that happened.
