Get lost. Wander down alleys. Sit in cafés and watch life pass by. Don't eat where the tourists do, but where you see locals. Just set off down a street and see where it leads. Look around the bends, over the rises. Get away from the crowd. I find that if I meander away from the tourists and tourist sites, away from what is too familiar and comfortable, it's much easier to adapt to the rhythm of a place, and to be more observant.
We are unlikely to long remember the smell and buzz of a flower garden in spring, the awe of gazing for the first time at the mountain we intend to climb, the caress of a tropical breeze, the thrill of a huge roller coaster, the wonder of our first wild bear, or the adrenaline of rafting white water. Our photographs need to bring these and other sensations back, to trigger our memories, and to communicate how we felt to others. To do this, we need to think and feel as much as look when setting out to make photographs.
