Perhaps you enjoy taking pictures of feet or are fed up with the mundane angle of view one usually sees. And it gives me a state of peace, the feeling of a pause. Main reason: maybe it's inborn autism.....
The world below my head…can further enable the view and the formed pattern of the graphic design one usually comes across. The possible layout is different from that of ordinary shooting.
And the world below my head…will inevitably confront my own feet. Why not embrace them in the picture, shoot from the top of ‘my very own’ height to capture the view below my feet above the ground; or, with some weird composition in mind, make it an issue of special record of my own.
Of course, it also leaves a bit of memory of the shoes of their clothing-maniac owner!
