depth of field?

Well this isnt the picture I had hoped for, it was as you can probably guess a robin through the trees.
Only I was sitting on the floor looking up through them because I had been clearing the patch under some bushes when this little red chested fella came along and looked very interested in my warm damp worm populated bit of earth!
So grabbing the camera and still chatting to him took his picture (yes I did ask him first) then the lovely fella said right thats enough as I realised I have lovely pictures of twigs and no Robin...

Decided now I have at last got an internet connection I would add a few back blips in
