  We consider four-point correlators in an excited quantum state of a field
theory. We show that, when the theory and state are holographic, a judiciously
applied Fourier transform produces high-quality images of point-like bulk
particles, revealing the geometry in which they move. For translation-invariant
states, the bulk Einstein's equations amount to local differential equations on
correlator data. In theories or states that are not holographic, images are too
blurry to extract a bulk geometry. We verify this for gauge theories at various
couplings and the 3D Ising model by adapting formulas from conformal Regge
theory.
