Thanks all !
Yes wish the birdie was a little bigger . Yes Shiva , our idea would have worked well here ! Maybe something to try for later. I need to figure out if I can take my own time between shots or like film, rewind and expose again
But, on the Nikons there is away to merge two RAW files, into a third and, in camera. I should try that and report back ...
Honestly I did not see the face while shooting. But I felt there was something in the interrelation of the mountain and the Kestrel, when I took the shot. Then I saw it clearly when I was post processing and adjusted the crop accordingly.
Spot on Arati, it is a kestrel ! Yea, that was one crazy , memorable morning !
