There IS a way

Must learn it sometime.
Now and again it get this urge to shoot off up on to Beacon Edge. Just like that Bear ... "To see what I can see"
Due, of course, to the prevailing circumstances; I get the odd uninspired day. where Rockall gets shot at. 
This in not so much an emergency as a day nothing much was shot. Having got up the metaphorical mountain I liked the sky. I just fell out of love with it on screen.
I'm fully aware that there exists a way, other than my obvious ham-handed attempt, to selectively manipulate bits of a shot. It would be an awful lot easier if I knew what to call the facility I'm seeking.
