This photo is taken at a shutter speed of 1/1, aperture of F25, and ISO 320.  The focus of this photo is the typing hand. When I attempted to take the photo at different shutter speeds, I found that 3 seconds make the photo really blurry rather than showing movements, and 1/2 seconds make the photo not as blurry as I want it. While I like the photo for showing motion, I did not like how the photo is composed. I felt like there are too many objects in the frame, and the hand position in the photo seems awkward. I would probably remove a lot of the objects and give more room for the arm, putting the hand at the intersection between the line dividing the left third from the rest and the line dividing the bottom third from the rest.
