"This photo meets requirement 4, plants, as well as requirement 1, focus on the foreground. I used an aperture of f/5.6 and a shutter speed of 1/125 to achieve this field of depth. I tried to keep the tops of each of the flowers in focus, with their stems and backgrounds completely out of focus."

"This photo fills requirements 1 and 5, being a man made object and having the focus on the foreground. The background is completely blurred out, and even the distant rope is out of focus. For this photo, I used an aperture of f/8 and shutter speed 1/320 to capture both the highlights and shadows on the rope."

"This photo fills requirements 2, 3, and 4 by focusing on the midground, and being of both a plant and a bug. I had to increase my shutter speed to 1/200, as the bee was fluttering around a lot and it was very difficult to catch him in one spot. My aperture was at f/8, allowing me to blur both the foreground and background of the image."

"This photo fills requirement 2, focus on the midground, as well as requirement 4, plants. I used a 1/125 shutter speed and f/8 aperture to create the depth of field that allowed me to blur both the foreground and the background."

"This photo fills requirements 1 and 4--focus on the foreground and plants. I used a 1/125 shutter speed with a f/8 aperture to avoid motion blur because it was a windy day. I like it because only the one flower is really in sharp focus, with the stem and the other small flowers out of focus in the background."
