Loading my 35 mm SLR with slide film. Most likely this is to take end of the semester slides of student work during the final grading. Slides of student work are useful when explaining a new project to a class, allowing them to see successful examples. Also needed when applying for teaching jobs. In 1993 I was still more than a year away from worrying about that, but it was time to start building up a collection of good student slides in preparation for job seeking.
