I love rusty old things that are lying around in all sort of places. These horse shoes are on this rack at a farm that I sometimes pass on my walks.
Think about what details you want to show. I took this at a wide aperture (a low f number) so that I could get the details on the first horse shoe. I got in close to see the detail and reminded myself to consider the length of focus of my lens.
What rusty thing can you find today to show the details?
