Hi empeejay
Thanks for the tips. I find keys very difficult, partly because of the terminology but also, sometimes my pictures may miss one specific area even though all other areas have been photographed.
Is there any reference that is more picture/illustration based available?
I'll take a look at the facebook group, though I am not a great fan of facebook. Though I could see a benefit it this case.
Thanks again to you and Eric. Gareth
