8、1877) in 1841. Talbots calotype was the firstnegative-to-positive process and the direct ancestor of the modern photograph. The calotype was revolutionary in its use of chemically treated paper in which areas hit by light became dark in tone, producing a negative image. This negative, as Talbot call
9、ed it, could then be used toprint multiple positive images on another piece of treated paper.The two processes produced very different results. The daguerreotype was a unique image that reproduced what was in front of the camera lens in minute, unselective detail and could not be duplicated. The cal
