Serious stuff!

It was the second meeting of the new village photography group this evening. After some discussion on apertures, depth of field and other technicalities, we went out into the garden to try out our cameras with some macro shots.
This is not one of them!
Here two of our more knowledgeable members are having a technical discussion! 
One of my macro shots can be seen in my extra.

(There seems to be an awful lot to learn!)
