I made this self portrait holding the camera in my left hand, and controlling it with my right hand on the iPad (out of frame, mounted on a floor stand). (I had to use a 2-second self-timer, to get time to get my right arm down.)
I am in my favorite reading spot, propped up on my space foam bed, with the iPad hands-free. Damn relaxing.
This is of course just the merest beginning, there are many vistas of use, for example shooting birds without spooking them, and so on.
