I am photographing the tangent point of a circle in which I am the center, the horizon is as far as I can see. At a framed point the horizon is flat, I cropped the image back to the original shape at which it enters the lens, the shape of the Earth, a Circle. To not only inform that the Earth/Horizon is curved but that the camera frames reality like our brain frames reality. There is an altering to meet a standard idea of what something is, what reality is.
