We compare the effect of 3-D poststack versus 3-D prestack imaging on seismic coherence, seismic amplitude, and seismic amplitude variation. We find that the improved resolution and amplitude preservation of the prestack imaging result in more sharply defined terminations and hence better delineation by coherence and amplitude gradients even though the (macro) velocity models used in both imaging approaches are laterally invariant [v(z)].
