France, Paris. Shoot from the hip. Beforehand, think of your composition, then adjust your camera settings, like focal length and exposure. Using a wide-angle lens gives you more depth of field and a larger image to crop.
This is a fun technique to use when walking through crowded streets. Also, try holding the camera over your head, an especially good way to expand the foreground.
These two techniques are more naturally used with smart phones, where image taking is less serious and more spontaneous.
