Aerial view of workers processing dried fish in Chittagong, Bangladesh. Food drying is one of the oldest methods of food preservation. Sun-drying, a specific type of food drying, involves placing food in the sun to remove water. This prevents the growth of microorganisms and slows down the decomposition process. In Bangladesh, many fishermen families have taken up sun-drying fish as their profession. Photographed on 12 February 2024.
