"Capture and share at least two images demonstrating your ability to control depth of field to achieve desired photographic effects.
The important point is that you should have a go at testing the theory and practice controlling depth of field as appropriate in your own images. You may wish to try some of these ideas:Close-up macro shots showing extremely narrow depths of field to pleasing effect.
Portrait or still-life shots with very narrow depths of field (it is fashionable in portrait photography to have, say, just the eyes in focus and the hair out of focus. This requires a large aperture.
Landscape shots where you have maximised depth of field.
Sports action or wildlife shots with a narrow depth of field on the subject to give a pleasing composition."
I didn't get many landscape shots for this one, everything seemed to have cranes or office buildings in it, but I'm quite pleased with the close ups. The one of the ball of wool is included as I wanted to achieve that effect with the previous set of yarn photos but didn't know how.
