I took this photo during an evening walk with my iPhone. I used no filters. I did nothing to it in Photoshop.
The weird colors were just part of the manhole cover. I’m not sure who painted the edges green or how rust seeped through the white paint to give a pinkish tinge.
My point is to always bring your camera with you. If you have a smartphone has a decent camera, all the better – you’ll have it with you to get that shot you would otherwise miss.
