Something that doesn't really help is Elka's natural ability to move at the very second the picture is taken, so that what would have been exactly the shot I want it instead, well, something else.
So, for your amusement, a series of these attempts. Really, I see so many beautiful pictures of dogs "in the field", I didn't realize the amount of casual skill those photographers were displaying. Although, I am working on teaching Elka a "stop" command, meant to be like "freeze" when we humans play freeze tag: stop and stay in your tracks! Maybe that will help.
Eventually, I either get a picture that's reasonably close to what I want, or I just give up. Either of these results in the camera being put away, and the walk resuming, which is really what Elka wants.
