Your photographs must clearly show the use of "extreme" shutter speeds and apertures. You are free to choose whatever subjects interest you.
Photo #1:Slow shutter speed. Try anywhere between 1 second and 1/60 second, depending on light. The subject (person or object) should be moving / blurred. This is best photographed with the camera on a tripod. Examples: Waterfall, sports, traffic flowing.
Photo #2: This image is of frozen movement. This is done with a very fast shutter speed. Try to capture something dynamic and interesting that really looks great frozen in time. Examples: Sports, animals running, jumping, skateboarding tricks.
Shutter speed = 1/250 or faster. You will need a lot of light. This photo would work best taken outside on a sunny day.
Photo #3: The third picture uses a large aperture. Try using the largest aperture available (f/4.5 or so for a regular lens). The goal is to have a clear foreground and blurred background. Both the background and the foreground should be interesting / beautiful. Examples: Portrait, flowers, pets, close-ups.
Photo #4: The fourth photo uses a small aperture. Try f/16 or smaller. You need good light to take a picture with a small aperture; or a long shutter speed; or both. Examples: Landscapes, city view, forest.
Try to find an expansive landscape with something interesting close to the lens and an attractive vista off in the distance. Both foreground and background should be in clear focus.
Photo #5: Photographer's choice. Get creative with your favourite method. Try a long exposure (1 second or more). Or try a zoom blur (zoom in or out during the exposure). Or try layering two shots of the same subject at different shutter speeds.
