If you want to take a family picture or a picture of yourself you use a tripod, a monopod, and so on. But I do not. (Are you kidding me? $60 for this? Hell no).
I try to find the better position for my camera, from which angle it would be better, on what hight, etc. Sometimes I use a chair (like for this photo) with a bunch of textbooks, binders, you know; or I can just put it on the floor and again with this bunch of books create something like that http://godvinv.tumblr.com/post/144746144125/emptiness-is-filling-me-to-the-point-of-agony
Another thing, may be the most challenging for me is to find where to stay/sit. Well, I mean it is just how you pose for the photographer. I have never done this before, so to figure it out still takes time. Plus I need to know timing of my timer, and to bring all these details together, to find this “ok” combination is quite interesting and challenging.
I find these pictures kind of extraordinary, unusual, weird for me. I would not identify this type of pictures as a “selfie, because there is none in front of the camera in the moment of taking a shot.
