Rectangles, Olympus XA2
Where do you see rectangles, everywhere? If you can imagine the world in front of you as a flat two dimensional plane it can be an interesting exercise to look for ways to divide it. It can be helpful to look through the viewfinder to generate that flat view and frame a scene but with practice you can spot images without the camera. So why would you want to do this? Like any exercise in seeing it helps to broaden your visual acuity.
