When I was in high school, I dreamed of being a filmmaker. I owned a Super 8 camera which shot little rolls of 8mm film—with no soundtrack—and would last about 3-4 minutes. Later, when I went to college, I was able to use the school lab to add sound and final edits by hand (that is, scotch tape and a razor knife), then convert to 16 mm.
Great fun and full of so many possibilities!
But it was expensive. A ten-minute film might run $100 or more, and this was when minimum wage was about $1.50 per hour. At any rate, I would then show the movie to other students in my film class and, if brave enough, outside on the dormitory wall.
