What howard carter improve as an archaeologist between 1892 and 1899

Although only 17, Carter was innovative in improving the methods of copying tomb decoration. In 1892, he worked under the tutelage of Flinders Petrie for one season at Amarna, the capital founded by the pharaoh Akhenaten. From 1894 to 1899, he worked with Édouard Naville at Deir el-Bahari, where he recorded the wall reliefs in the temple of Hatshepsut. So most likely the apprenticeship was what helped Howard Carter improve as an archaeologist.
