Large‐radius Weissenberg cameras equipped with image plates have become popular for the collection of X‐ray diffraction from protein crystals. However, it is not always easy to ensure in either design or practice that the image plates assume cylindrical geometry with respect to the crystal rotation axis. This article describes an algorithm that is capable of correcting for general distortions in image‐plate or camera geometry on these instruments.
