We describe two sets of Planetary Camera data for the same object. One was observed in such a way that it is adequately sampled (according to the Nyquist theorem) while the other was not adequately sampled. We discuss a variant of the ``roll deconvolution'' technique and demonstrate the advantages of this observing strategy for minimizing detector flaws. We show the results of attempting to restore each set of data using both the STSDAS ``Lucy'' and Weir's ``MEM'' routines. Our conclusion: The sampling theorem applies to WF/PC data, Surprise !?
