That's the greenfinch again!
Man, he had to model for you all the time while he was with you, hm?
And you had great fun with your new camera and shallow DOF, it is more than obvious .
yes I had a lot of fun testing the use of a reflex camera, and of my macro lens!! about the DOF, it's often because I don't managed to get the good one....
about the bird, I let him alone and quiet during the 3 weeks he stayed at home (I didn't want him to be afraid and disturbed); I took portraits (a lot!!!) few hours before giving him freedom, because he was able to fly for 3 days!
I hope he's well now!
