Ultra-realistic photograph, extra high resolution, 16:9. Cairo, late 18th century, morning in the dyers' quarter. Large clay and brick vats of indigo, madder and saffron dye; long strips of freshly dyed cotton and linen hanging from wooden poles across the lane in deep blue, red and yellow. A master dyer with blue-stained arms lifts dripping cloth from a vat; apprentices wring fabric; a cloth merchant in a striped kaftan and turban checks the color against daylight; a Coptic customer waits with folded cloth; a donkey carries bundles of undyed linen.
