For this lesson, it is assumed that the student probably has heard the basic raps on the theory of holography and how it’s different from photography has followed directions either from this site or some other source and has the necessary equipment (laser, beamspreader, isolation table, object, holographic film and chemistry) to set up the necessary optical configuration to record a hologram, (preferably the type known as Single Beam Reflection) (the Googling is left up to the reader, start with Single Beam Reflection Hologram or Denisyuk hologram) and is ready to load the holographic film into the set up.
By the time the student holographer is ready to make an exposure, they will have built the optical configuration. It is probably unlikely that they have worked in a photographic darkroom, which is the void that this unit will try to fill. Unless the students have no interest in the process and have been coerced into the lab, they will have a positive mental attitude toward the whole thing, and the only danger is that they might be so over-enthusiastic that they might not want to go through the discipline of a systematic shakedown of the exposure and development process. But even if their exuberance overpowers common sense, they will come back to this lesson when they want to make the best possible result.
