There is also a serious catch in terms of what you can photograph - the fastest speed you can coax out of a Daguerrotype plate is less than that of printing paper - let's say maybe ISO 0.1 in terms of modern film ISO ratings. That alone introduces other limitations. But a silver iodide modern film of the same size would have about the same resolution, if you could keep it in place for the long exposure times.
