For accurate absorption‐correction calculations, a precise knowledge of the crystal shape is essential. A least‐squares determination of the coordinates of the crystal apices according to the analytical expressions derived is obtained by taking a series of silhouette photographs of the crystal directly on an X‐ray diffractometer with a pinhole in the incident beam and using soft continuous X‐radiation.
