Raw Hirum! Hit it!

生ヒルム・ん！打々

The raw film (undeveloped) is placed in a hand-cranked projector and scratched and melted using an electric drill or soldering iron. The differences between the front and back of the raw film are displayed simultaneously in a multi-image display, and the differences between the image projected on the screen (transmitted image) and the image from the lamp side (reflected image) are observed, as well as the frame boundaries.
