It is shown that anomalous X‐ray diffuse scattering can be treated as a hologram providing information on the local environment of the anomalous scatterer. In contrast with standard holography with atomic resolution, holographic oscillations of several percent of the total measured signal can be achieved by choosing suitable photon energies. The problem of virtual images can be solved very easily in the case of both centrosymmetric and non‐centrosymmetric structures. Moreover, these holograms are not overlapped by dense and strong Kossel line patterns.
