Workers hang hundreds of color-dyed sheets of cloth on a bamboo framework to dry in a dyeing factory in Narayanganj, Bangladesh on May 23, 2023. The drying process usually takes 4 hours, with each set of 200 pieces at a time to dry in temperatures over 42 degrees Celsius. Workers use hats for protection from the scorching heat because they have to constantly turn the colorful fabrics so that they dry perfectly in the sunlight.
