I just started playing with Photosphere on my tablet about two weeks ago. Basically you take a picture and it lights up a series of blue dots of additional shots that need to be taken. You keep moving around/up/down until you get all of the dots. When they are done the phone/tablet will stitch them together into a photosphere. With people, if they are pretty close, you may need to take 2-3 images to get all of them in. If they move between the shots then you can end up with headless/missing torso, etc. I did some at my sister-in-law at Christmas and got her feet and no head. Kind of funny, but the rest of the room looks great.
Note, you can click on the opposite side of the creek to see what it was like from the Confederate side if you like.
