2 - Blur

Out-of-focus pictures are often seen as mistakes, but blur can also be a creative, artful choice.

1 - Zebra Crossings

Crossings marked with stripes are a favourite haunt of street photographers. I know them as zebra crossings, but you may call them marked crosswalks. They differ worldwide, but everybody halts and waits at them, bringing together an infinite variety of colours and patterns and shapes - so much is possible.

Wait along with others to cross a road, and size up your potential subject from behind. Look for patterns that complement or clash with the crossing - from spotted dogs to striped shirts.
