I enjoy seeing beauty in things that my mind initially overlooks or judges negatively. I was struck by this manhole cover while I was walking on a road near our house in Sedona, and pulled my iPhone out of my pocket to make a photograph of it. I'd walked by it many times, but on this day something inside drew me to look at it more deeply. I realized that I was drawn to the textures and patterns of the metal grate and the contrasting gravel creeping over it at the lower edge of it. The vertical and horizontal bars also make an interesting contrast to the circular shape of the sewer cover, which is matched by the concrete edge of the sewer opening.
Once I got home and opened this image on my computer, I felt the impulse to convert it to black and white so that the textures and shapes had more prominence. Wow - that really made it come alive for me.
When I looked at this photograph as I was writing about it, I saw something else: the word "sewer" could also refer to someone sewing, and the horizontal and vertical bars then could be seen as the interweaving threads of a piece of cloth. A suit of armor, perhaps? :-)
While I don't encourage you to only look at the ground when you're out walking, perhaps you might glance now and then at the earth beneath your feet and see what you discover.
