I’m still getting the hang of this new bird photography technique; my problem at the moment is getting the shutter speed, depth of field and angle right. Obviously, since it is by remote, I have to plan it ahead. Birds being birds, they’re never quite where you want them to be for a photo, and some – but not all – species get frightened by the shutter, so they scarper as soon as they hear something.

So that’s why the remote images are not so sharp. I had this suspicion that perhaps my lens needs calibrating, but other things are sharp, so it probably means that my shutter speed is too low for the rapid movements of birds, or the point of focus isn’t quite where it needs to be in any given photo relative to the subject (the bird in the photo).
