As a professional photographer, I constantly need to exercise my eyes to keep them fit for purpose. Some days I just go out and spend my time looking at the floor.
My brain and eyes are like a radar set: they scan the world around me, all the angles, searching out scenes or objects to zero in on and capture.
Restricting the radar beam can be a great exercise: looking up, looking down, looking for squares, circles, red things, blue things. Limitations help you train.
Looking down at the floor, especially with a camera or lens that focuses close-up, can be a hugely satisfying experience.
Textures, tiny things we normally walk past, patterns.. all take on a new feeling when you spend time to study them.
And then there is the process of 'collecting things'. I've said it many times before, moving to a small flat in Tokyo helped me redraw my attitude towards collecting stuff. I simply don't have the space anymore to hoard. So I collect things with my camera.
Numbers are one of those things.
