This is inside an old player piano. These wooden and felt knobs hit the strings to produce sound from the piano.
This is George Armstrong Custer’s gravestone. Though I do not believe he was buried here, in the Black Hills, this is the place where he died.
The lighting for this picture was dim, so my shutter speed was 1/50 of a second, and my ISO was about 500 . My f-stop was at 3.2, which also brought more light into the picture. This was taken with my Canon 60D and Tamron macro lens.
