With aperture, the lower the aperture the shorter your focal distance is. The first photo is an aperture of f/22, and the second is an aperture of f/5.6. As you can see, the larger aperture has more of the background in focus. Typically for portraits you want a smaller aperture, and a larger aperture for landscapes.


Raising your ISO will brighten your image, at the cost of image quality. The first photo is an ISO of 26000, and the second is an ISO of 100. Raising your ISO should be a last effort.


Typically, in order to get a blur motion photo, you would need a shutter speed of 1/250 sec. In order to get freeze motion, you would need a shutter speed of 1/500 sec.
