The (low budget) advertising brief called for a swimmer in competition....a reference to the summer Olympics. In a small town in the dead of winter finding a swimming pool (let alone a heated one) was an impossibility. We found a half empty pool in someone's backyard ... scrubbed it clean and filled it with water. Our crew cleaned the snow away from the angle of view and we persuaded the client to invest in a brilliant model who was former military and a scuba diver of note which translates to someone with superb discipline. He braved the hyperthermic conditions for shot after shot. In case you were wondering about the use of Photoshop - it was in it's infancy and securing the services of a decent retoucher was dicey given our time restraint.
