This image is really working for me. I just LOVE nesting images and this one is special. Your exposure throughout, esp the bird, looks spot on. The bird's crest and head show up so well. There nest is expertly laid out, wire and all. You have it all here.
I like everything here William and to my eye it is one of your best. The exposure on the bird is spot on, as is the colour of the bird and IQ. I like also that the bird is not imaged as the ubiquitous caricature that cormorants and shags seem to present (though nothing wrong with such images). It is just refreshing to see the bird looking quite casual.
Very nice Will. Agree with everything that has been said by others. The only thing that slightly spoils it for me is the black area top left, but there was not much you could have done about that.
Hi Will, you have absolutely nailed the exposure on the Shag, as one can see a variety of different hues of green. Lovely eye, raised crest, and you even managed a great HA too. Well captured.
