This is an example of what happens when taking the same picture with multiple different F-stop settings. The pictures required changing other settings to maintain a proper exposure. This shows the depth of field go from very narrow, to wide enough to get the entire field in focus.
The shutter speed test is similar to the F-stop, but instead it shows the affect that changing the shutter speed does on a moving subject. I chose Wynoochee Falls, a large waterfall in the southern Olympics.
