Theres are really lovely JB. I love the serene look and sharpness of the first it was well taken as for the second well thats them in all their glory isn’t it right place right time and you had your camera along.
The first is a fine shot, love the dropplets, but the long straight neck is a problem for me. I would prefer a curved or the classic S shaped neck.
The second is grand except that the bird was moving into shadow and there is a very distinct shadow line across the breast.
They are easily photgraphed, the trick is getting a shot that stands out from all the normal ones, these for me are normal swan shots.
