Prompt
A real photograph in the observational documentary genre, captured on 35mm film with a 35mm lens at f/5.6 for generous depth of field and open visible grain. A single soft overcast daylight key from high front falls evenly across surfaces with loose open shading gathering lightly under ledges and folds, finished in a plain desaturated grade with honest midtone contrast and unpolished texture.
Wide 16:9 frame. In dim blue water a broad stone stairway descends into deep sediment with only its upper steps clear and the rest disappearing into the silt floor, seen from above at a shallow angle and framed as a medium shot. No people, hands or faces appear; no readable words, numbers or logos appear and every sign, plate and facade marking on the structures is blank or plain colour.
