These two photos were both taken to test the use of ISO settings on a photo, in order to make the photo look grainier than the other. The more ISO, the grainier the image becomes, leaving the one with less ISO to appear smoother. The first was shot at 100 ISO, making the photo look smoother in comparison to the second, which was shot at 3200 ISO.
These three photos were each taken on different aperture settings in order to set different objects in the photo in focus. With aperture control, the higher the number, the smaller the hole, meaning that only a small amount of light will be allowed in. This puts only a front subject in focus, as seen with this clock which Robson is holding. As you can see, on the aperture of 22, only the clock is in focus, and Robson and the van behind is out of focus.
With this photo, the aperture setting was at 11, making it a medium aperture level. This allowed part of the background (aka, Robson) to come more into focus as opposed to how out of focus it was in the aperture 22 photo.
Finally, shot as aperture 3.5, it is clear that the background and the foreground of this image is in focus and can clearly be seen. This is because the hole in the camera allows more light to come through the lens.
