Coherent diffraction imaging (CDI) with 8 keV X‐rays is used to image a gold nanostructure. Experimental details are given and frequently encountered problems such as missing low spatial frequency information and parasitic slit scattering are discussed. As a possible remedy, hard X‐ray Fourier transform holography (FTH) is presented and its robustness with respect to the diffraction pattern quality is demonstrated. It is shown that even with a few‐second exposure to an unfocussed beam, the object structure can be clearly recognised. FTH in combination with CDI is ideal for single‐shot imaging of micron‐sized objects using femtosecond flashes of hard X‐rays at the upcoming free‐electron laser facilities in the USA, Japan and Germany.
