This picture is not mine. I found this picture to be very interesting because you can prevent kids from being distracted while taking a picture.It come in two versions, one with a 7-inch articulating arm and another with an 11-inch arm for use with longer lenses. When taking a picture of children, it is not easy to have them concentrate on the camera, I think this will probably the solution.
